DataCentersaremore relevantthanever

In an increasingly digital world, data is the cornerstone for both business and societal functions As data generation and consumption surges, data centers have emerged as the backbone of the digital economy. Adhering to stringent standards for physical and cybersecurity, data centers play a crucial role in ensuring the secure storage, processing and dissemination of critical information for business and government

As digitalization, AI, and quantum technology advance, the future role of the data center industry will become increasingly pivotal, transforming businss operations and interactions This evolution has significant socioeconomic implications, impacting society and our global competitiveness Modern data centers enable flexible working methods, support the future healthcare system and contribute to the development of a welfare society

An uncertain world calls for bold solutions With a new national AI strategy, unstable geopolitical conditions, and AI changing the game for almost all sectors, data centers are more relevant than ever

Sustainability and energy efficiency are key focus areas as the industry prepares to support future highdensity AI applications Whilst AI undoubtedly will use more energy, it can also be part of the solution.

In Denmark, we started to see new investments popping up in 2024 after a dry spell in 2023 and 2022. As predicted in the past few market reports, uncertainty regarding AI has put a damper on new investments, as hyperscalers and colos alike have been figuring out the consequences. What will AI mean for design, power, and cooling? What are the consequences for networks and fiber cables to be able to handle the growing amount of data? What will future business models look like when it comes to investments in land and data centers? There is no definitive answers, but they are questions we seek to address in this magazine and at Data Centers Denmark 2025

Denmarks new AI strategy: like building an electric car without a battery

At the end of 2024, the Danish government launched a new national AI strategy Despite containing positive elements and ambitious objectives, the new AI strategy lacks focus on infrastructure and energy The Danish Data Center Industry encourages digitization and the development of green power to be integrated, so that Denmark can succeed in the double transition, where we are ambitious in the digital as well as the green areas

This will continue to be a focus area in 2025, in close cooperation with TSOs, energy companies, and the members in the data center ecosystem

In this magazine, you can read our input to the national AI strategy, input we encourage being incorporated into future evaluations of the national strategy

Focus on energy, power and grid connection Energy remains essential for our industry, and DDI will address it across events throughout the year in close cooperation with our Nordic partners

At DataCloud Global Congress 2025, the Nordic associations will come together in a panel about renewable energy and “what to learn from the Nordics” sharing our experiences, challenges and success stories with the broader industry

At DDI we are determined to support initiatives and projects that will truly help decarbonize the data center industry.

DDI has grown significantly over the years. We have expanded our secretariat significantly this year to support our members and provide them with high quality content, events and networking opportunities With the help of our board of directors, I am excited to continue building on the great foundation we have built in the past 8 years

Mario Draghi's report from September 2024 paints a bleak picture of Europe's competitiveness under pressure. Draghi also points to new technology and artificial intelligence, particularly generative AI, as a major opportunity for improved competitiveness and innovation

Recommendations from the Danish Data Center Industry

In November 2024, The Danish Data Center Industry recommended that the following principles be incorporated into a national AI strategy The strategy published in December 2024 did not include infrastructure and energy, but our recommendations still stand

Infrastructure and Capacity:

The strategy should recognize the importance of digital infrastructure and data center capacity to handle large amounts of data in a secure and sustainable manner, and to provide the necessary computing power required by modern digitalization and AI utilization This includes access to green energy, a robust and future-proof power grid, and network connections

Energy Efficiency and Sustainability:

The strategy should create access to green energy sources that can be integrated into our energy systems The expansion of renewable energy is too slow, and the permitting processes should be accelerated At the same time, Denmark should promote investments in data centers that are as energy efficient as possible The use of surplus heat for district heating and industry should also be promoted by removing the price cap on surplus heat The goal should be for Denmark to be a leading and exporting country for green data center innovation. The Net Zero Innovation Hub in Fredericia is a good example of the role data centers can play in collaborations.

Education and Skills Development:

The strategy hould ensure investments in education and training of current and future workforce so that employees can meet the technological demands of AI and data center operations This can be achieved through strengthened cooperation with and prioritization of technical schools, universities, etc , that educate employees for critical infrastructure

Regional Development:

The strategy should consider how future AI data centers can further contribute to regional development and create economic growth throughout Denmark Data centers bring new and well-paid jobs to local communities

Collaboration and Partnerships in Research and Innovation:

The strategy should support cross-sector collaboration between public, private, and academic institutions so that data centers can function as research and innovation centers for the development of sustainable AI technologies and participate in public-private partnerships (PPP).

Datacenters are frontrunners in innovation of green and secure solutions

As cloud solutions develop, global companies such as Google, Microsoft, and AWS are investing in energy efficiency for their hyperscale data centers, which are now some of the world's most sustainable facilities According to the International Energy Agency, data centers worldwide have managed to keep energy consumption down despite the explosive data growth over the last 10 years

Data centers are investing in new and green energy sources such as solar and wind through Power Purchase Agreements (PPAs) to reduce their carbon footprint This also paves the way for more renewable energy in Denmark For example, Google's PPA agreements have led to the construction of five large solar parks with a capacity of 167 MW of green electricity, which is added to the Danish power grid.

Denmark is a leader in utilizing surplus heat for district heating, industry, and agriculture with larger installations such as Meta in Odense, GlobalConnect and Microsoft in Høje-Taastrup, JN Data in Silkeborg, and Penta Infra in Albertslund However, there are still structural, geographical, technical, and business barriers to fully exploiting the potential in Denmark and Europe, and the potential for surplus heat must therefore be assessed from data center to data center

The industry collaborates on innovation and new solutions, including through the Net Zero Innovation Hub in Fredericia, which is a unique collaboration across the industry with participation from companies such as Microsoft, Google, Data4, Danfoss, Vertiv, and Schneider Electric

Jobs,

Education and Local community

The data center industry creates growth and development in various areas of the local community:

Job creation:

Data centers create a range of direct and indirect job opportunities, from temporary jobs during the construction phase to permanent jobs such as craftsmen and electricians, technicians and engineers, security guards, operations managers, and IT specialists The long-term presence of high-tech companies can help brand and attract other industries to the local area, thereby creating additional indirect jobs and growth in the area

Infrastructure:

Data centers often invest in upgrades to local infrastructure that benefit the community, including roads, electricity, and internet connections. Data centers also invest significantly in projects and activities within the local community.

Education, skills development, and research: Data centers work closely with educational institutions In Denmark, institutions such as Fredericia Maskinmesterskole, University College Lillebælt, and Mercantec have close collaborations with several industry players, including Google, Apple, and Meta, to develop and promote targeted education and training programs From 2020-24, Microsoft has reached 200,000 Danes with digital upskilling as part of its data center investment

Data centers are also involved in research and development, which helps create additional educational and research opportunities for students and researchers In Denmark, DTU, Aalborg University, and SDU are among those working on the development of optimization technologies for the data center industry

2025MARKETREPORT ExecutiveSummary

European market outlook:

The European data center market is undergoing a major transformation, driven by institutional investors and private equity targeting the growing colocation segment As Europe prepares for an AI-powered future, data center demand is projected to grow from 10 GW today to 35 GW by 2030 potentially accounting for 5% of the continent’s total power usage

Danish data center market outlook:

In Denmark, the data center sector is maturing rapidly, with hyperscale operations currently representing 60% of all workloads However, a minor temporary slowdown in hyperscale buildouts is expected by 2026 At the same time, the colocation market is accelerating, forecasted to reach 40% of workloads by 2028 This segment is becoming more fragmented, with domestic players expanding and new entrants emerging

Impact of AI on data center investments:

To support growing AI and high-performance computing demands, operators are deploying highdensity racks (100 kW+), which require advanced power and cooling systems Limited land and grid capacity in traditional markets are shifting investment focus toward Tier II and III locations, with an emphasis on on-site generation, microgrids, and hybrid energy solutions.

End-user strategies:

AI is prompting IT leaders to adopt hybrid strategies leveraging colocation for training and cloud for inference while reassessing infrastructure design and energy flexibility To remain competitive, colocation providers must embrace modular infrastructure, sustainable design, and participation in reserve energy markets

AI is prompting IT leaders to adopt hybrid strategies, leveraging colocation for training and cloud for inference, while reassessing infrastructure design and energy flexibility To remain competitive, colocation providers are increasingly turning to modular infrastructure, sustainable design, and participating in reserve energy markets Denmark offers a unique positioning for sustainable data center investments, given the favourable market conditions

Energy infrastructure developments: In Denmark, the TSO anticipates significant growth in data center power demand, reinforcing the need for new sourcing strategies Data centers are expected to contribute to the national green transition by supporting hydrogen, grid balancing, and waste heat reuse. Regulatory pressure is also increasing, pushing hyperscalers to improve emissions reporting and energy tracking.

More data centers are expected to reuse their excess

2025MARKETREPORT MarketComposition

The estimated installed capacity stands at 264 megawatts (MW), reflecting an increase of 44 MW from the previous year.

Around, 139 MW is under construction (Q1), with completion expected within the next 1-2 years. Some projects initially scheduled for 2024 have been delayed and are now expected to be completed in 2025.

With several projects going live this year, the total installed capacity is expected to potentially reach an estimated total of 406MW by the end of 2025

DDI’s investment outlook in Denmark is based on the following premises:

In the short term, upcoming data center construction with an additional power capacity of 139 MW to be scalable within the next 1-2 years In the long term, potential for an additional +526MW in reserved data center power capacity, in the pipeline by the end of 2028.

The current capacity distribution in Denmark derives largely from hyperscale workloads, which includes both hyperscale enterprise and hyperscale cloud activity The Danish market continues to be primarily driven by hyperscale capacity at 60%, colocation 30% and enterprise 10%

The colocation segment has been steadily growing in Denmark, and is expected to increase significantly over the next few years By 2028, the colo segment is projected to make up 40% of of the total workload in the country.

Robust,scalableand adaptable AI Infrastructure

Kasper Tjørntved Davidsen joined Topdanmark as CIO in 2023 to implement an industry-changing digital transformation His task: Make it easier to be a customer while also strengthening the underlying infrastructure and operations One of the goals: To be able to handle 80% of all customer inquiries in under 20 seconds AI would later come to play a key role in this mission

As part of this transformation, Topdanmark has announced massive investments into consolidating policy platforms and digitalization of its core business

Q: How has your role as CIO at Topdanmark evolved since you took on the position in 2023?

Kasper: Since taking on the role of CIO at Topdanmark in 2023, my responsibilities have evolved in many ways, including making sure that Topdanmark takes a leading role in driving digital enablement for customers.

The rapid growth in AI has been a significant factor in this evolution, as it presents both opportunities and challenges. We possibly have a “once in a lifetime” emergence of a new technology that can significantly increase our operational efficiency while developing innovative solutions that benefit our customers right at the engagement level

At the same time, we live by the trust of our customers, and ensuring that we build compliant and secure solutions that operate with maximum operational stability is pivotal to our strategy, and to our success, in this rapidly changing technological landscape

“Stable & secure” is, and will always be, at the core of what we do This includes staying ahead of compliance requirements such as DORA and GDPR, which are critical for protecting our data and systems In my view, it really boils down to striking a balance between maintaining our daily operations while still positioning us to drive innovation, introduce change and capitalize on emerging technologies

Stable and Secure at the center Topdanmark was one of the first insurance companies in Denmark to work with AI, in particular Machine Learning, as well as being early adopters of ethical principles for the use of AI These principles ensure that the use of AI is reliable, fact-based and unbiased, so that the models can be used safely and only for the intended purpose

With growing investments in AI and IT infrastructure also comes an inherent need for increased focus on security across the stack

Q: What strategies do you employ to maintain robust security across your IT infrastructure?

Kasper: Our security strategy is built on several key elements We ensure compliance with relevant laws and regulations, such as DORA and GDPR, to protect data and systems to the highest standards. Security is integrated with both our IT and overall business strategy, supporting our goals and ensuring continuity and growth. We base our strategy on thorough risk assessments and an understanding of the current threat landscape, tailoring our measures to address the most pressing threats. Additionally, we consider our organization's security maturity level, ensuring our strategies are realistic and achievable while continuously improving our security practices

Moreover, we maintain an active test regime to ensure that our governance and test policies are effective in practice This involves regular testing and validation of our security measures to identify any gaps or weaknesses

By continuously monitoring and evaluating our security controls, we can make necessary adjustments and improvements, ensuring that our policies are not only theoretically sound and “look good on slides”, but are also practically effective in protecting our organization

Topdanmark’s on-premise data center setup is an essential part of the framework behind their IT strategy to support a rapidly growing digital business footprint It is meant to ensure enhanced network segmentation, enhanced workload segmentation, updated hardware, and improved security

Q: What are the key challenges you face in managing your on-premise data center, and how do you address them?

Kasper: One of the primary challenges in managing our on-premise data center is maintaining "full-stack" competencies, as we do not benefit from having parts or all of the infrastructure delivered as Infrastructure as a Service (IaaS) or similar solutions

To address this, we ensure that competencies are maintained either through sourcing or internally

Another significant challenge is the cost and inflexibility associated with both horizontal and vertical scaling, which are both time-consuming and expensive This is a condition we have to accept as a consequence of staying on-premise

About Kasper Tjørntved Davidsen

Kasper Tjørntved Davidsen is a seasoned leader in the field of information technology, currently serving as the Chief Information Officer (CIO) and member of the Group Executive Management at Topdanmark, one of Denmark's leading insurance companies

With +15 years of experience in leading IT strategy, digital transformations, and innovation, Kasper is driving Topdanmark's technological initiatives and InsurTech agenda to build the digital insurance company of the future, where he has positioned the company as a frontrunner in GenAI with the launch of TopGPT, one of the first customer-facing GPTenabled chatbot in European insurance

Prior to his role at Topdanmark, Kasper served as Group CTO of PayTech powerhouse, Nets/Nexi Group, where he led large-scale integrations across Europe after years of heavy M&A activity while ensuring stable & secure operations for critical payments infrastructure in the region Kasper has also held leadership positions in LEMAN and KMD

"Digital First" is a key focus of Topdanmark's strategy, prioritizing the use of digital opportunities and AI before looking into traditional methods This approach is crucial for achieving their ambitious digital goals

Topdanmark's AI strategy is built on three key pillars: the implementation of Copilots for internal operations, the development of TopGPT to increase efficiency and satisfaction in customer interactions, and a forwardlooking perspective on the evolving role of AI within the company

Q: How do you ensure that your IT architecture remains scalable and adaptable to future technological advancements?

Kasper: When Topdanmark embarked on the next leg of its datacenter journey, we faced a significant 'lifecycle management' challenge regarding our datacenter infrastructure. To avoid a scenario where multiple infrastructure renewals would occur simultaneously, we defined our preferred future lifecycle management approach before starting the hardware refresh. This structured implementation approach ensures that our IT architecture remains scalable and adaptable to future technological advancements

Additionally, we have adopted a “cloud-right” strategy in our architecture, ensuring that our platforms are increasingly adaptable to migrate to the cloud while also being capable of absorbing workloads This strategic optionality allows us to leverage the benefits of cloud where we see fit, such as scalability and flexibility, while maintaining control over our infrastructure By continuously evaluating and updating our cloud strategy, we ensure that our IT architecture can adapt and continue to support our long-term business goals

Q: Looking ahead, what trends or challenges will shape your 2025-2026?

Kasper: As we continue to advance our AI capabilities over the next few years, I believe that the critical questions we are asking ourselves now will evolve with the increasing global demand for compute to power AI models and new regulatory paradigms

One of these questions is how we establish an AIcapable infrastructure setup that effectively balances the on-prem hosting of specialized Large Language Models while utilizing the largest models that we take for granted today, where cost tradeoffs are necessary

This involves finding ‘the right balance’ between maintaining control and security with on-premises solutions, where potentially fine-tuned, smaller, more specialized models are best fit, while continuing to tap into the performance, flexibility, and scalability offered by cloud-based models where relevant

A significant challenge ahead lies in understanding and scoping the necessary raw compute power required for running in-house models Of course, there is a limit to the investment size we would like to undertake, but I believe that we need to explore whether to secure and control our own compute capabilities when we see AI becoming even more deeply integrated into our core business.

Ensuring our competitive edge by running models for workflows requiring on-prem processing and potentially achieving cost advantages by planning batch workflows that require heavy computing but are not time-critical is essential This also requires experimenting, upskilling, and identifying the optimal position required for opensource models and eventually fine-tuning on-prem, continuing to balance the dependency on cloud-based closed models

Ultimately, we need to ensure that our AI infrastructure is robust, scalable, and adaptable to achieve our strategic objectives without setting us on a trajectory towards irreversible vendor lock-in

Achaoticandcrazyworld withbrandnew opportunities

Among many other titles, Anders Kjærulff can also list techno-critic, IT provocateur, and co-founder of the think tank "Analogiseringsstyrelsen" (ed: Analogisation Agency) on his business card He describes himself not as a Luddite but compares himself to a literary critic –someone who loves literature but remains critical of it He urges us to think and talk much more seriously about how digitalization and AI actually impacts our society and human relationships

His presentation began with a tour de force through the vast range of possibilities and mishaps that digital development has brought about A lot has happened since humanity set foot on the Moon in 1969 with the assistance of a computer boasting just 4 KB of RAM From the Eliza effect and the anthropomorphization of machines to dreams of transhumanism and singularity, we now face a present and future with, among other things, Neuralink and artificial intelligence.

“Throughout history, many have asked whether humans are even competent enough to inhabit the future. Will we be saved as a species, or simply eradicated because machines find us to be in the way?" Anders Kjærulff reflected, though he is primarily focused on future opportunities.

"Your industry will gain great benefits from all of this –self-driving cars, for example, will be a major advantage for the data center sector Personally, however, I don’t think they will become popular until all manually driven cars are removed at once Otherwise, they will perform maneuvers that self-driving cars cannot comprehend," he assessed

The IT debater generally encouraged the industry to adopt a self-critical and proactive stance, particularly regarding the massive energy consumption of data centers

“Google and Microsoft each consume around 24 TWh globally – more than many nations This will only increase in the future, and it will likely trigger protests We are already seeing this in Ireland, where data centers now account for more than 20% of electricity consumption, leading to ‘brownouts’ that cause periodic power outages for regular consumers," Anders Kjærulff pointed out.

Throughout history, many have asked whether humans are even competent enough to inhabit the future. Will we be saved as a species, or simply eradicated because machines find us to be in the way?

At the same time, he advocated for more robust backup systems for the most essential societal functions –ideally with local and preferably analog emergency systems

"For instance, the U S Navy uses sound-powered telephones that require no electricity, and they have now become so advanced that they can be used over several kilometers We need to think about backups that are not overly complicated – they need to be simple," he emphasized passionately

Overall, the techno-critic is skeptical about the vulnerability of our digital society.

"Part of the problem is that much of the support is outsourced – perhaps to India – and for various reasons, you might suddenly find yourself in a situation where you cannot access it That’s why it is extremely important that we in Denmark maintain local support competencies Do you have local support?" Anders Kjærulff asked rhetorically

He also recommended taking an interest in complex yet pressing issues such as data security

"We actually have a declared goal of digital sovereignty in Europe – I think it’s time for people to take this seriously, especially now that Trump has terminated the joint data agreement between the EU and the U S , " warned Anders Kjærulff, who is also aware of the ethical issues within the data center industry

If you want to avoid public shaming, ensure complete transparency regarding your energy and water consumption We need the numbers on the table; otherwise, people will start protesting! And do you have policies or ethical guidelines in place if, for example, the government suddenly demands access to your data?" he posed as one of many difficult questions for the audience to ponder.

As mentioned, Anders Kjærulff primarily focuses on opportunities, and despite everything, he remains optimistic about the future

"I believe things will work out – but not if we just continue to go with the flow We need to start making demands and building better infrastructure with improved security in Denmark Some of that infrastructure must be analog – we must have the ability to pull a big red lever and revert to what we previously had in analog form," he recommended "I believe many of these changes are already underway –and I also believe it will be a good business opportunity for you "

Before Anders Kjærulff's presentation, the Danish Data Center Industry set the stage with a 'fireside chat,' where CEO Henrik Hansen highlighted the significant and rapid changes occurring

"It’s a crazy, crazy world right now, and every single day, something happens that impacts our industry A lot has changed for us as an association as well – now we’re being invited to everything because people have truly realized how important our industry is," said Henrik Hansen

"That’s why we also need to carefully consider how we best interact with our surroundings We have become a crucial part of almost everything that happens in modern society "

INTERVIEW: JOAKIM PETERSEN

Poweringthefuture: Investmenttrendsand challengesintheNordics

Picture: Joakim Petersen (left) joins the ribbon-cutting ceremony on a new data center site in Copenhagen.

The Danish Data Center market is expected to double within the next few years From being a predominately hyperscale-based data center market, analysts are now expecting an increase in colocation workloads This is changing market dynamics, as new investors and players are entering the market at a pivotal point

Q: What do you see as the key trends and factors that will drive data center investments in Denmark and the Nordics over the next 1-5 years?

Joakim: I see several trends and factors poised to influence investments in Denmark and the Nordics over the next 1-5 years

Notably, the retail and wholesale colocation sectors, along with cloud availability zones, are experiencing significant expansion across the Nordics, with ongoing developments in both major cities and tier-2 locations. As workloads continue to grow, mainly due to the increasing demands of AI, the need for additional capacity is becoming critical. A significant trend in the Nordics is the heightened focus on AI, prompting a shift in industry priorities. Whereas previous considerations emphasized factors like power capacity, time to market, zoning, and buildability with respect to latency, the AI landscape requires a reevaluation of these metrics There is a stronger emphasis on power requirements, with data centers needing to accommodate up to gigawatts of power per campus

This shift leads to considerable operational expenditure (OPEX) related to power costs, making even slight savings per kilowatt-hour impactful for data providers

Investors will carefully assess these classic external factors when deciding on new projects Additionally, macroeconomic considerations, particularly government incentives for AI development - whether direct or indirect - will play a crucial role The extent to which countries and communities support the growth of the industry and the establishment of data centers that facilitate AI operations will also influence investment decisions

Short-term concerns include the availability of AI chipsets and the speed and scale of their deployment, both of which are critical for organizations aiming to leverage AI technologies.

And of course, how will Europe react in a new global geopolitical dynamic? With developing assets for cloud sovereignty and maybe an accelerated regional AI play?

Q: How do you see the Danish/Nordic (investment) market evolving in terms of technology, sustainability, and infrastructure?

Joakim: The investment landscape in the Danish and Nordic markets is evolving significantly, driven largely by the increasing demand for AI large language model (LLM) training workloads This trend is propelled by the region's abundant power resources, characterized by a low CO2 footprint and comparatively favorable energy costs relative to other areas in EMEA While extensive construction activity is still emerging, substantial land banking is taking place to prepare for future AI developments

As we anticipate heightened density and energy demands from these systems, the exploration of advanced cooling solutions such as direct-to-chip and immersion cooling technologies will likely become more prevalent. From an infrastructure perspective, the focus must extend beyond the data center itself to encompass how these facilities generate and source power. Key considerations involve whether energy is exclusively sourced from the grid or if there's a shift toward onsite generation methods. The potential development of nuclear energy, including microreactors and small modular reactors (SMRs), raises important questions about implementation strategies and their implications for competitiveness across countries, regions, and communities

Furthermore, advancements in connectivity, such as the introduction of hollow core fiber, could significantly influence data center location decisions, as this technology has the potential to extend the reach of availability zones and enhance performance across wide-area networks

Sustainability remains a core aspect of the Nordic value proposition, exemplified by our low CO2 energy grid and strong emphasis on optimizing the use of "waste" heat generated from data processing Integrating this waste heat into existing district heating systems and circular industrial symbiosis initiatives is essential An illustrative example is Denmark's Kalundborg Symbiosis, a model of resource sharing that has been operational since 1972 This commitment to sustainability is poised to evolve, delivering economic benefits while promoting responsible resource utilization in society.

Q: Looking forward, what do you see as the primary risks associated with data center investments? How will we see companies mitigating these risks, particularly in terms of power and land availability?

Joakim: Power remains a critical determinant in data center investments, and this focus is unlikely to change in the foreseeable future Investors are increasingly prioritizing securing substantial power resources, often quantified in three-digit megavolt-amperes (MVAs) In situations where off-grid power solutions are viable, a crucial consideration is the ease of implementation and the establishment of supportive public frameworks that ensure swift access to power This can be effectively integrated with grid-based workloads, allowing seamless transitions to the grid when intermittent renewable sources, such as solar and wind, are unavailable.

Additionally, incorporating provisions for island-mode operations - utilizing gas turbines or other nonintermittent energy sources - can enhance resilience and potentially reduce overall energy costs. As a result, regions with diverse local and regional power generation facilities will be particularly attractive to investors

On the matter of grid connections, which are a top priority for investors, there is a pressing need for assurance regarding security, uptime, and capacity The Nordics face competition from other European regions in terms of time to market, making proactive engagement from Transmission System Operators (TSOs) essential during the due diligence process

On the land availability front, a smooth and transparent zoning regime is crucial The maturity of land, ideally pre-zoned for industrial or data center use, is a significant consideration for investors For sites lacking pre-zoning, investors will evaluate zoning frameworks and their potential pathways to secure the necessary approvals efficiently Across various countries, regions, and municipalities, investors diligently analyze risks to minimize external influences that could jeopardize timelines before finalizing investment decisions

In Denmark, we have demonstrated a strong capability in navigating the planning and zoning systems, which positively contributes to the investment climate. Historically, our agility in these processes has positioned Denmark favorably in the competitive data center investment landscape.

Q: Access to powered land has become a vital factor for data center expansion and investment. In your experience, how are companies navigating the challenges of land acquisition, and what strategies are being employed to secure land and prime locations?

Joakim: Access to powered land is indeed critical for data center growth, with various factors influencing different market segments For instance, retail data centers in capital regions may not require hundreds of megawatts (MWs) but still need adequately zoned land with accessible power, typically in the range of 20 MW+ However, securing such land and immediate power in cities like Oslo or Stockholm can pose significant challenges

Currently, we see considerable land banking activities in suburban and rural areas of the Nordics, particularly for AI and cloud applications. Companies engage in land banking to ensure they can navigate the zoning and permitting processes successfully while securing reliable power ramp-up agreements with grid operators. Power Purchase Agreements (PPAs) aligned with corporate sustainability goals and cost management, along with agreements for utilizing residual heat in district heating systems or with neighboring industries, are also essential components of this strategy

It is vital to recognize that land suitable for data center development often commands a premium price compared to its current usage as farmland or for other industrial purposes Consequently, clients typically seek demonstrable proof of potential future data center use before finalizing transactions To mitigate risks during this process, many companies prefer to secure exclusive options on powered land, which allows them to meet all necessary criteria and ensures they can effectively plan their construction and operational rollout

Additionally, certain investor types, such as colocation providers, often require the securing of one or two anchor lease tenants before making final investment decisions However, as we have observed in the Nordics, it is crucial to temper expectations regarding the short-term development of all land acquisitions. The industry operates under its own dynamics, and not every land deal will translate into immediate project construction.

Q: What are you most excited about in terms of new developments, technologies, or projects on the market in 2025-2026?

FromsmallDanish manufacturertoleading datacentersupplier

While NOVENCO’s data center journey started with Meta in 2013, the true breakthrough happened five years later In 2019, NOVENCO announced that they had been awarded a major contract by Meta to supply advanced cooling solutions for two new 175 MW data center sites in the United States

It took five years to be approved as a strategic partner by Meta for US-based data center projects, but today, NOVENCO is still the only non-American manufacturer to supply cooling solutions to Meta’s data centers in the United States

After continued growth since 2019, NOVENCO has invested in new production facilities and moved to a new domicile in December 2023 John Jørgensen summarizes:

“Data Center business has grown strongly, and we have therefore invested in a new factory with a dedicated production flow line that has enabled us to increase efficiency, thereby optimizing costs and ensuring on-time delivery with zero defects.”

Sustainability and energy efficiency are of the essence

Sometimes, you are in the right place at the right time Or, in NOVENCO’s case, you have the right product in a time with massive investments and growth in the data center industry

Jørgensen tells us that NOVENCO’s patented ZerAx® axial flow fans are the most energy efficient on the world market This, combined with a high recyclability rate (98%), helps ensure the product has a low carbon footprint

Energy efficiency is essential for the data center industry, and recent legislation has underscored the importance of minimizing energy usage in data centers

In addition, TCO is an important factor The technology utilized in NOVENCO’s ZerAx® ventilators ensures that they can run for 20+ years without service and maintenance This is important not just in terms of scope 3 emissions for NOVENCO’s customers, but also in ensuring zero downtime

Significant growth and increased market share

While it is difficult to be approved as a supplier to the major data center hyperscalers, it can make a significant difference for the business Since 2019, NOVENCO has delivered data center cooling solutions to hyperscalers with a collective capacity of appr 1 6GW, thereby gaining a significant market share In 2024, data center projects accounted for appr 50% of NOVENCO’s annual turnover

“For a company of our size, compared to our much larger competitors, this is a major success story,” Jørgensen concludes

DigitalRealty'sAI-Ready datacenterhosts Denmark'sSupercomputer

In this member spotlight, Pernille Hoffmann, Managing Director, Nordics, at Digital Realty, gives her perspectives on Denmark’s first supercomputer and the data center industry in Denmark.

The Novo Nordisk Foundation and EIFO have brought one of the world’s most powerful supercomputers to Denmark, and in 2024, the Danish Centre for AI innovation (DCAI) was established to operate the supercomputer

The supercomputer was officially inaugurated in October 2024 by NVIDIA CEO Jensen Huang, his Majesty King Frederik X of Denmark, and DCAI CEO Nadia Carlsten

Popularly known as ‘Gefion’, the supercomputer is hosted by Digital Realty in one of its AI-ready data centers in Denmark In Norse mythology, Gefion is known as the goddess for agriculture, fertility, abundance, and prosperity, and is often translated as “the generous one ”

Gefion is made up of 191 DGX H100 systems with a total of 1,528 NVIDIA H100 Tensor Core GPUs and 382 Intel Xeon Platinum CPUs connected by Quantum 2 InfiniBand.

I believe Denmark and the Nordics have the prerequisites to become an AI hub in the coming years. We have solid infrastructure, a highly robust ecosystem, and favorable conditions for sustainability. In my opinion, as a country we are ready for this.

Denmark’s solid infrastructure and robust ecosystem enables innovation. The Gefion project has come to life in a public-private partnership between Novo Nordisk Foundation, EIFO, NVIDIA, Eviden, and Digital Realty The Danish Centre for AI Innovation, which is supported by Novo Nordisk Foundation and EIFO, owns and operates the supercomputer Any generated revenue will be reinvested in the initiative

“I believe Denmark and the Nordics have the prerequisites to become an AI hub in the coming years We have solid infrastructure, a highly robust ecosystem, and favorable conditions for sustainability In my opinion, as a country we are ready for this,” Pernille comments

The project allows both public and private sectors to access the computer to complete research Incoming research projects will be evaluated on several parameters, including ethics

In October 2024 it was announced that a project from the Danish meteorological institute would be the first to run on the system, but researchers from the University of Copenhagen, Technical University of Denmark (DTU); Go Autonomous, a startup in the transportation field; and Teton, a healthcare startup; are also among the six winning proposals running as a part of Gefion’s pilot phase.

Why Digital Realty? Operational Excellence, confidentiality and discretion at the core

According to Pernille, three key factors influenced the decision to choose Digital Realty as the host for the supercomputer First and foremost, the need for an AIready data center Additionally, a strong focus on sustainability and operational excellence played a crucial role Pernille explains: “Sustainability has been a central theme throughout the entire process ”

In an industry where confidentiality, security, and discretion are critical, these factors were also essential in the decision-making process

From an operational standpoint, hosting the supercomputer is no different from serving any other customer Digital Realty provides hosting under standard colocation conditions, with minimal adjustments required.

“Security and confidentiality are top priorities for our customers Hosting this supercomputer follows the same setup as any other customer no special arrangements are needed, as they seamlessly integrate into our existing operations This is possible because we already meet all necessary requirements ”

INTERVIEW:ALBERTO RAVAGNI

Innovativepartnerships drivesustainabilityat scaleindatacenters

The urgency for achieving Net Zero and transforming the global energy system to meet the 1 5°C goal has never been more critical Although 2023 was a landmark year for the energy sector, with the share of renewables rising to 14 6%, and, combined with nuclear, accounting for over 18% of total primary energy consumption, 2023 also saw record consumption of fossil fuels, highlighting the significant challenges that remain Meanwhile, 2024 marked the hottest year on record

In this context, Alberto Ravagni discusses the biggest challenges data centers face in becoming more sustainable, and the innovative solutions being developed to address these issues

Q: What are the biggest challenges data centers face in becoming more sustainable?

Alberto: One of the biggest challenges data centers face in becoming more sustainable is fulfilling the simultaneous requirements of exponential growth and decarbonization.

Data centers require high energy consumption to power and cool the vast amounts of computing equipment (Scope 1 and 2 emissions) This is compounded by the need for reliable, 24/7 power, which can be difficult to source entirely from low carbon energy Additionally, the environmental impact of scope 3 emissions: materials and electronic waste and the need for efficient water usage in cooling systems are significant hurdles, deonding on the data center location Balancing the growing demand for data processing with the imperative to reduce carbon footprints is a complex task

Addressing Scope 3 emissions is another major challenge Data centers must work closely with suppliers to ensure that materials and components are sourced sustainably and that the entire value chain is optimized for minimal environmental impact This involves rigorous reporting and management of emissions from construction, operations, and end-of-life disposal of equipment

Finally, ensuring reliable backup power while maintaining sustainability is crucial Data centers are increasingly exploring cleaner alternatives such as battery storage systems and renewable energy sources for backup power such as hydrogen and clean fuels These solutions help maintain continuous operations progressing simultaneously towards sustainability goals

Q: What are some of the most significant innovations in data center technology that are helping to achieve sustainability at scale? (Can you provide examples?)

Alberto: Several innovations are making a substantial impact on data center sustainability For instance, liquid and immersion cooling technology, where servers heat is removed by dielectric fluids, significantly improve cooling efficiency, reduces energy consumption and enable heat reuse. Another example is the use of software-defined data centers, AI supported optimization and infrastructure virtualization, leading to optimized resource utilization and reduced energy waste. Additionally, hyperscale architecture allows for more efficient scaling of data center operations, further enhancing sustainability.

How is the Net Zero Innovation Hub addressing these challenges through innovation and partnerships?

Alberto: The Net Zero Innovation Hub is at the forefront of addressing these sustainability challenges through a combination of innovation and strategic partnerships We are fostering collaboration between data center operators, suppliers and innovators to accelerate the development and deployment of sustainable technologies Innovative technologies must be de-risked before they can be scaled Our initiatives include pilot projects for clean backup power solutions, heat reuse systems, and the interaction of data centers with the electric grid By creating a platform for knowledge sharing and public engagement, we aim to drive the industry towards a net-zero future

Role of Partnerships

In an increasingly complex world, it is becoming increasingly clear that a new approach to colllaboration is needed The Net Zero Innovation Hub is just one example of cross-sector partnerships driving the industry forward

Q: How crucial are partnerships in driving the data center industry towards net-zero goals?

Alberto: Partnerships are absolutely vital in driving the data center industry towards net-zero goals The complexity and scale of the challenges we face in achieving sustainability require a collaborative approach By working together, data center operators, technology providers, and energy companies can pool their resources, expertise, and innovations to develop and implement effective solutions These partnerships enable us to leverage diverse perspectives and capabilities, accelerating our progress towards a sustainable future.

Q: Can you share some successful examples of collaborations that have made a significant impact on sustainability?

Alberto: One notable example is the collaboration between EcoDataCenter and CoreWeave EcoDataCenter, a Swedish company, has been building eco-friendly data centers that use renewable energy and innovative cooling technologies Their partnership with CoreWeave, a major AI compute provider, has led to the development of sustainable data centers that significantly reduce carbon emissions

Another example is the partnership between LuxConnect and various green energy providers, which has enabled LuxConnect to offer carbon-neutral data center facilities powered entirely by certified hydroelectricity These collaborations demonstrate the power of partnerships in driving meaningful progress towards sustainability in the data center industry

I also look forward to seeing the impact of collaborations such as the one between WA3RM and atNorth This partnership is poised to transform heat recycling at the new atNorth site in Denmark, enabling large-scale greenhouse operations and community heating solutions.

Future outlook

As the data center industry continues to evolve, sustainability and innovation is becoming increasingly critical Staying ahead of emerging trends in a rapidly changing landscape is crucial We asked Alberto Ravagni to share his perspectives on the industry's future, focusing on the exciting developments in sustainability and innovation

Looking ahead, what trends do you foresee in the data center industry regarding sustainability and innovation? How do you see these trends shaping the future of data centers?

Alberto: In the coming years, I foresee several key trends driving sustainability and innovation in the data center industry

First, the integration of renewable energy sources will become even more prevalent, with data centers increasingly relying on solar, wind, and hydroelectric power to reduce their carbon footprints. Data centers will become more integrated in the future energy systems providing grid services and supporting local communities. Additionally, advancements in cooling technologies, such as liquid cooling and immersion cooling, will significantly enhance energy efficiency The adoption of AI and machine learning for optimizing data center operations will also play a crucial role in improving sustainability

Edge computing will play a pivotal role in the future of data centers by bringing data processing closer to the source of data generation This approach significantly reduces latency, enhances real-time data processing, and optimizes bandwidth usage As the demand for low-latency applications like IoT, autonomous vehicles, and smart cities grows, edge computing will become increasingly essential It complements traditional centralized data centers by offloading some of the processing tasks, thereby improving overall efficiency and resilience This decentralized model will enable data centers to better handle the exponential growth in data and support the next generation of digital infrastructure

Q: What are you most excited about in terms of new developments, technologies or projects on the market in 2025-2026?

Alberto: I am particularly excited about the current advancements in AI infrastructure and the future implementation of quantum computing at scale These technologies have the potential to revolutionize data processing and analytics, enabling us to tackle complex problems more efficiently

Additionally, the development of hybrid cooling solutions that combine various liquid cooling methods with traditional air-cooling systems is a significant step forward in enhancing data center efficiency I am also enthusiastic about the increasing collaboration between data center operators and clean tech industries, which will drive innovative solutions for sustainability These developments will not only improve the performance and sustainability of data centers but also contribute to a more sustainable and technologically advanced future

About Alberto Ravagni and the Net Zero Innovation Hub

Alberto Ravagni is the CEO of the Net Zero Innovation Hub for Data Centers.

Alberto Ravagni brings over 20 years of experience in the energy industry and is a clean energy architect and industry expert in clean energy, energy storage, and fuel cell technologies

Danfossleadsthe waywithclimate friendlydatacenter

"Almost everything you can see from here belongs to Danfoss though not the church over there, but the founder of Danfoss is buried there In fact, he’s buried with his face turned towards Danfoss, so he can keep an eye on the company," shared the day's host, Director Jakob Jul Jensen, Data Center Business Development at Danfoss, in his welcome speech

The networking event included a review of Danfoss' digital transformation and a visit to the company's datacenter, both of which align well with the current trends in the industry, where several interesting developments are unfolding

"AI is taking up a lot of our attention right now, and we're in close dialogue with Energinet and the Danish Energy Agency, as there are several issues to address," said Henrik Hansen, Director of the Datacenter Industry, in a status update.

"A lot is happening right now including the availability of capacity in the power grid versus actual needs. There's much to manage here so all stakeholders are ready for the large-scale AI rollout."

For Danfoss, the goal is to become the preferred partner in reducing customers' carbon footprints This is a priority for the giant corporation, founded in 1933 in Nordborg, which now operates over 100 production sites in more than 100 countries and employs over 41,000 people

"Green transformation is our business, and we believe Danfoss is a key to the solution also when it comes to datacenters We aim to be number 1 or 2 in all our

business areas; otherwise, we believe it’s better not to participate," said Kasper Sckerl, Vice President, Head of IT Operations & Platforms at Danfoss

The climate agenda has also literally moved close to Danfoss' own datacenter in Nordborg The location was assessed to be at risk of flooding during cloudbursts, so in February 2019, they broke ground on a new climatefriendly datacenter Or rather, two centers, to ensure operational security, building an identical 2nd Node center 40 kilometers away

"Everything is redundantly connected in a 'Zero Outage Design ' Over the past 12 months, we haven't had a single second of downtime," stated Kasper Sckerl, whose team also seized the opportunity of the new construction to implement several green initiatives

"For us, it's important to take our own medicine, and we have a three-step strategy to become completely carbon neutral reduce, reuse, and replace. The campus you're in now is already carbon neutral, and in the datacenter, we use machine learning to minimize power loss in energy transformation and employ Danfoss' oil-free cooling compressor, which is 50% more efficient than traditional ones," he explained

Utilizing surplus heat is also an integrated part of the new datacenters, which are expected this year to provide 25% of the entire heating demand for the large Nordborg campus The expectation was for a slightly higher share, but with precise liquid-based spot cooling, the datacenter has proven more energy-efficient than expected, generating less surplus heat

After the presentations, the networking meeting participants enjoyed a site visit in the brilliant latesummer weather The datacenter is built in a container design behind a fence but without an actual building around the containers This decision weighed the security benefit of a closed building against the flexibility of easy and quick redesign in the future by simply swapping out one or more containers

The design is also modular, with 250 MW capacity in one container from the start, expanded to 500 KW in Phase 2 in 2022 Phases 3 and 4 are prepared for a total capacity of 750 MW and 1 GW, respectively, while Danfoss, as mentioned, runs an identical setup at a second location 40 kilometers away

In a building next to the datacenter, heat exchangers and heat pumps are used to recover the 24°C cooling water's excess heat This water is cooled to 19°C before being returned, and chillers are installed as backup cooling at the datacenter

The heat pumps raise the water temperature to 63°C, making it suitable for heating The system can connect to the public district heating network, but it currently operates in a closed loop with Danfoss' local campus district heating system, which can easily absorb the heat

On the green side, Danfoss has also invested in a stake in the Horns Rev offshore wind farms, and the company has its own 2 MW solar park right next to the Nordborg campus Plans are underway to establish a battery storage system to store power and smooth fluctuations.

Back inside, another Danfoss director, in his role as chairman of the Net Zero Innovation Hub, discussed the progress of this newly established pan-European organization

"We want to innovate collaboratively we can't do it alone, which is why we’re a hub aiming to make a difference through partnerships," said Chairman Dietmar Baro, Vice President, Systems & Technology, Danfoss

"It might seem strange that we have competitors like Google and Microsoft as founders and work with companies like Apple But they don’t see each other as competitors in this context," he emphasized

"We are looking for new ideas in collaboration with industry, universities, and others to bring together various competencies and cover all areas. We also aim to engage governments and other institutions to build a blueprint that can be used elsewhere, and we're exploring various funding options," Dietmar Baro shared.

Initially, the Net Zero Innovation Hub focuses on three initiatives: excess heat utilization, carbon-free energy for datacenters including in backup power and reducing CO2 in building materials

"We started with these three projects because we’ve been a small team from the outset We have tons of ideas, but we also want to achieve something I’m married and have kids, and if I try to please everyone, nothing will get done and they’ll all be unhappy," Dietmar Baro joked

He assured that many different ideas and possibilities are being explored in the longer term and praised the industry players for numerous inquiries with input and suggestions

The final item of the day was a panel debate with a single but highly complex question for the industry: Are we ready for AI?

"From the co-lo side, we're ready and not ready," said Sales Director Anders Hansen from Stack Infrastructure, referring to the need for much higher energy density.

“The density per square meter isn't even close to what AI requires today even in datacenters only a few years old If we want to use power, we must also move the heat We thought servers could handle more and more heat, but they can’t Let’s see what AI actually brings but as a co-lo operator, we’re challenged by AI in the short term," asserted Anders Hansen

Regional Business Lead Denmark Rasmus Bisgaard from NVIDIA pointed out that Denmark generally isn’t at the forefront of AI investments On the contrary, we’re losing ground compared to other Nordic countries, and the Dell representative on the panel shared the same concern

"We're lightyears behind and have been for the past two or three years We could have closed the gap with Asia, but we didn’t, because we don’t have the capacity for sustainable AI growth in Denmark," assessed Senior Server Specialist Thue Stahl from Dell.

"There is a need for infrastructure within the country's borders to protect IP rights that’s the impression I get from the customers I work with daily. Customers are skeptical and cautious."

The security issue was echoed by Stack: "Many large companies want to use AI, but they're reluctant to use the public cloud When you see security breaches on a daily basis, you want to use it in an environment you control We receive many price inquiries and so on, but the big boom hasn’t come yet, as electricity is required Few sites can provide what’s needed that’s also an issue here," said Anders Hansen

From Schneider, there was a reminder that only a few customers are truly engaged in AI and few understand the actual need

"There’s talk of AI as one entity, but AI encompasses many things And good luck designing something for an AI need you don’t actually know," said Country Sales Director Søren Schrøder from the Secure Power Division at Schneider Electric "When Rasmus from NVIDIA says they’re three months delayed with a project, it only affects three customers It’s not 100 customers, as very few actors are still leading the way in AI development."

atNorthCEO:Market dynamicsarechangingin thedatacenterbusiness

atNorth recently announced their newest data center project to date: a heat reuse enabled mega data center in Denmark With an initial capacity of 250MW, the site will have the ability to scale up to several hundred megawatts, implementing heat reuse to heat largescale greenhouses, local housing and opportunities for sustainable power production

Although the site will not be ready for a few years, the scale of the project puts atNorth in a position where it is set to be one of the largest data center providers in Denmark within a few years

DEN02 is atNorth’s second data center in Denmark

The first site, DEN01, which is located near Ballerup, will have a 30MW capacity and is due to open in April 2025

DEN02 - from project to implementation DEN02 will cater to colocation and build-to-suit projects and will be specifically designed for data-intensive businesses such as hyper scalers and companies running AI and High-Performance Computing workloads.

“In our mind it's a blueprint of how our future data centers will look, meaning that it’s a symbiosis project And of course, the building itself will benefit from the green electricity grids in Denmark,” Magnus explains

While a lot is still subject to the municipal process, the hope is to start construction of DEN02 no later than Q1 2026 When it starts, the goal is for the project to be a benefit to the local community; “We have a policy that we will leave as many jobs as possible within the local community or create as many jobs as possible This means that we will, where possible, prefer to use local contractors and local people for construction and for operation ”

The recent construction of an atNorth datacenter in Iceland is a prime example of this policy In an area with relatively few inhabitants, 93% of the workforce that was used on the construction came from the local community

As for DEN02, the goal is for the data center and adjacent industries to bring in local jobs: “The data center itself will of course bring in a lot of jobs, but the greenhouse project will bring further jobs in terms of the jobs related to the data center.”

In our mind it's a blueprint of how our future data centers will look, meaning that it’s a symbiosis project. And of course, the building itself will benefit from the green electricity grids in Denmark.

Construction of the greenhouses will not take place until well after construction on the data center has started, but Magnus adds: “The idea is that they will be ready to utilize the extra heat as soon as the data center is live ”

Heat reuse has great potential – but also challenges

When it comes to heat reuse, Magnus explains: “All our new projects are set for heat reuse

Unfortunately, we will be building DEN02 in an area with relatively few inhabitants, so local district heating will only benefit a couple thousand homes

Therefore, we have partnered with WARM who will build a greenhouse on basically the same plot, and they will benefit from the excess heat There will also be space for other heat off-takers, and we are already starting to investigate which companies that might be.”

There are, however, also challenges when it comes to heat reuse. As previously addressed by DDI, companies are facing challenges and roadblocks via regulation, in Denmark specifically via the price cap on excess heat.

When asked about the challenges atNorth faces regarding heat reuse, the message is clear: “Not related to this specific project, but we are facing a lot of challenges when it comes to heat reuse, especially on the regulatory side The regulators need to step in and make this an easier process ”

Denmark - a future hub for AI workloads

While atNorth has built data centers in Iceland, Finland and Sweden, they have chosen Denmark as the location for their biggest data center yet And while atNorth sees Denmark as a great option for future HPC workloads, Magnus does have some advice for the Danish market:

“For some reason, Denmark is not as well-known as a data center location Most of the hyper scalers have done self-built projects in Denmark, but as a colocation destination, Denmark is not that well-known I do not fully understand the reason for that I think that a lot of potential customers and industry players are not aware of how green the electricity grid is in Denmark ”

The main drivers behind atNorth choosing Denmark include access to renewable energy, being able to fulfill requirements in terms of heat reuse, and access to powered land.

“There are many advantages to Denmark, for example proximity to central Europe, access to power and renewable energy, and potential for heat reuse projects.”

Magnus adds: “that is something very few are aware of, but our projects will benefit from that. And especially in Jutland, the grid is very green with very high renewability on the grids ”

“atNorth is focusing highly on high density workloads traditionally known as HPC (high performance computing) In terms of AI, we are currently in the era of machine learning, and that era will eventually transition to inference It is our strong belief that Denmark will be a great option as a location ”

There are many advantages to Denmark, for example proximity to central Europe, access to power and renewable energy, and potential for heat reuse projects.

AI workloads are changing the game What is the future for AI and HPC workloads in a world where demands for data center capacity are on the rise? And will the Nordics be able to keep up as a competitive region? Magnus tells us:

“Market dynamics are changing in the data center business and that is very interesting The market has been dominated by hyperscalers Due to AI, the market is changing, and this obviously changes how things are done to an extent ”

As for future outlooks in terms of living up to the demands for capacity? Magnus concludes: “We must live up to the growing demands, otherwise someone else will I feel that Europe is falling a bit behind, especially on the AI front, because we can’t cater to the demand, and Europe simply needs to step up their game and take part in this revolution”.

Children,sustainability, andourdigitalfuture

Nordic Data Center Week was held for the first time in September 2024 The event is a collaboration between the Nordic Data Center organizations aimed at promoting knowledge and understanding of the role of data centers in a digitized society

CEO Henrik Hansen reflects on the week: “This is the first time we have held Nordic Data Center Week, and the interest has been enormous We have learned that there is great interest in our industry – but we need to become even better at communicating the essential functions we fulfill This experience has given us the motivation to continue the good work of conveying the role of data centers in society ”

Head of Strategy & Operations, Merima Dzanic, elaborates: “The purpose of Nordic Data Center Week is to spread the message about the role of data centers in society and to create a framework for local communities, businesses, and data centers to work together to create optimal conditions for green transition and digitalization.”

Technological Understanding and Career Opportunities in the Curriculum

In Viborg, Fredericia, and Esbjerg, 150 students in 5th and 6th grades received an introduction to the essential functions of data centers in society

At Bulk in Esbjerg, two 6th-grade classes got an upclose look at the data center and the support functions that keep it running "You might be the only children in Denmark who have been inside a data center," said Site Manager Rune Bråten "It’s actually quite unique "

Security in the data center was the first thing the children noticed, and it was also the first item on the agenda "Security is very important in a data center," emphasized Rune Bråten "We must protect both our customers' data and each other to ensure no one gets hurt "

Data Centers Are Essential for Roblox and for Mom to Go

to Work

The Data Center Industry believes that data centers' role in digitalization and the green transition is a topic of great interest to Danish children Additionally, it plays a crucial part in their digital education and technological understanding

"I am impressed by the knowledge these children have and how quickly they understood the role a data center plays in their daily lives Now that they have visited a data center, they also understand that there’s an entire industry behind the internet," said Merima Dzanic, Head of Operations & Strategy at the Data Center Industry "For children of this age, terms like CPU (Central Processing Unit), hard drive, power supply, and coolers are already part of everyday life, perhaps because they were born digital This will be a big advantage when they enter the workforce."

For many children, it was eye-opening to realize that the everyday activities they take for granted like playing games and sending messages on their phones depend on a data center.

We have learned that there is great interest in our industry – but we need to become even better at communicating the essential functions we fulfill. This experience has given us the motivation to continue the good work of conveying the role of data centers in society.

Collaboration is key to securing tomorrow's workforce

The school visits also offered an opportunity to discuss job opportunities and career paths in data centers

During each visit, employees shared insights into daily life in a data center and the educational paths that led them to a career in the industry

In the coming years, the data center industry expects challenges in finding qualified labor, particularly in technical fields As a relatively new industry in Denmark, lack of awareness is a factor hindering its potential

In the Q&A sessions, there was widespread interest in how to get a job at a data center The children asked about salaries, when they could start working, and whether working in a data center is cool

In Fredericia, Business Fredericia's job ambassador Ruth Axø also expressed enthusiasm for Nordic Data Center Week: "As a job ambassador, I am excited to see bridges being built between young people, education, and the business sector. Knowledge of technological understanding, sustainability, and digitalization has become essential for Danish youth to be competitive in the future job market Close collaboration between tech companies and schools is essential to ensure these skills "

The Sustainable Data Center of the Future –Designed by school children?

As part of the program, all participating children were challenged to design the world’s most sustainable data center A prize for the class fund was up for grabs as motivation, and most children participated with great enthusiasm and creative ideas

The winning design from Kvaglund School in Esbjerg stood out for incorporating sustainable materials and for thinking creatively and outside the box in their solutions The design included using groundwater as a cooling solution, securing power supply with solar panels on the roof and wind turbines, and building the surrounding fence from recycled plastic and metal Finally, drones would monitor the area and predict natural disasters

On behalf of the Danish Data Center Industry, Rune Bråten (DDI board member) from Bulk Data Centers, visited Kvaglund School to present the prize to the delighted children.

DDIandBulkbring togetherkeystakeholders foradialogueonthe crucialroleofdatacenters

The roundtable featured discussions on the consequences of the rapid developments in artificial intelligence, which places much greater demands on design, infrastructure, and energy consumption, while also emphasizing the central role of data centers in modern digital societies

Participants in the roundtable discussion included leading figures from the district heating sector, Energinet, and the Danish Energy Agency, from the public sector's procurement and knowledge center, as well as from major international operators of and suppliers to data centers, in addition to the hosts from Bulk and the Data Center Industry

Rasmus Bisgaard, Regional Business Lead Denmark at NVIDIA, set the tone by providing a brief overview of how quickly AI development is actually progressing:

"Every six months, we double performance, and it requires twice as much computing power. So far, it is primarily humans who ask AI systems for help, but soon we will see AI agents asking another AI agent, who asks a third AI agent, and so on. This is where the huge data consumption will come," said Rasmus Bisgaard.

The roundtable discussion was based on this rapid development, which will lead to significantly higher energy consumption Transparency, flexibility, and integration were three key words in the debate, reflecting some of the common desires on both sides of the table – from both public and private actors The desire from, among others, the Danish Energy Agency and Energinet was for the data center industry to be more open – for example, about future plans and needs On the other hand, there was a call for clearer and more proactive announcements, for example, regarding the purchase of system services for balancing the power grid There was agreement on both sides of the table that more dialogue on specific issues is needed

The open and informal atmosphere at Folkemødet provided the perfect setting for the discussions, and although the participants were actually gathered around a square table in Allinge, the debate covered the relevant topics that had been set out in advance

"It was a very good and constructive discussion, where we also touched on some of the sore points – for example, in relation to various obstacles that need to be removed to achieve the common goals," says CEO Henrik Hansen, Danish Data Center Industry

Co-organizer Bulk Infrastructure, which operates overseas fiber networks and data centers in Norway and Denmark, was also very pleased with the outcome of the roundtable discussion

"At Bulk, it is an important focus that both customers and industry players are aware of the major upheavals the entire sector is facing with the development of artificial intelligence. Therefore, we also push for dialogues like this roundtable discussion, where we can bring people together on the right solutions across sectors," says Jon Gravråk, CEO of Bulk Infrastructure.

"It was very encouraging to hear the strong commitment from all sides with a strong willingness to come together and solve the common challenges It gives great appetite to continue the dialogue, and we have agreed to keep the topics on the agenda – both politically and in the broader public," says Henrik Hansen

Since Folkemødet in 2024, DDI has taken the initiative to continue the dialogue by bringing the relevant actors together on a regular and more binding basis

The price cap on the utilization of surplus heat has been a controversial issue in the energy industry since 2021

CEO Henrik Hansen comments, "It is good news that the price cap, which has been a major barrier to the use of surplus heat from, among other things, data centers, is finally being removed It has taken a long time, but we would like to thank everyone who, together with the Data Center Industry, has fought to stop this obstacle to the green transition "

The data center industry's position has been that the price cap had a negative impact on the green transition, as it has imposed increased risks and costs on district heating companies

At the same time, the timing has been incomprehensible, as Denmark has simultaneously proposed the implementation of the EU's Energy Efficiency Directive (EED) into Danish legislation. This directive specifically requires data centers, including those in Denmark, to utilize excess heat for district heating, among other things. Thus, the two pieces of legislation have directly contradicted each other.

By removing the price cap, it is now possible to prevent surplus heat from disappearing into thin air, but less coal, oil, gas and biomass can also be used to produce district heating for consumers

"Utilization of surplus heat is one of Denmark's strong green cards With the decision of the Danish Parliament to remove the price cap on surplus heat, it will be easier to use surplus heat from data centers in the district heating network Data centers are increasingly looking to Denmark and the Nordic countries when investing in new facilities, but it requires a stable and sustainable infrastructure to maintain the investments," explains Henrik Hansen

Now we can future-proof Danish sustainable investment

In practice, the price cap has meant that many projects to utilize surplus and waste heat from industry have been dropped, and investments in development have been put on hold or dropped altogether These projects are now ready to be realized, says Dansk Fjernvarme

Since its implementation, the price cap has been an unnecessary barrier to the use of surplus heat, including from data centers It has prevented and delayed the initiation of projects and has specifically resulted in district heating consumers facing more expensive and environmentally damaging heating supplies for a longer period than necessary, as pointed out by Viborg Varme in connection with a surplus heat project in Viborg Municipality

Surplus heat currently accounts for approximately 4 percent of Denmark's district heating production, but with this agreement, the government and the parties to the agreement want to support the fact that it can be much more in the future. Estimates suggest that existing surplus heat could cover approximately 20 percent of district heating production. But the potential is even greater as further investments are made in data centers and PTX facilities

"We are now removing a concrete barrier and providing a freer framework so that surplus heat can develop In return, the district heating companies have a greater responsibility to ensure that projects with companies on surplus heat are economically justifiable and beneficial to consumers The ceiling made sense to protect consumers, but we can now see that the framework has become too tight I am pleased that we, together with the parties, have agreed on a solution , " says Minister of Climate, Energy and Utilities Lars Aagaard to Ritzau

datacenter

With this new agreement, Microsoft will capture surplus heat within the data center through an air-to-liquid heat exchanger and redirect it in the form of heated water through a series of pipes to the local district heating network Heat pumps installed by VEKS will then boost the temperature, while a heat exchanger and underground pipes will deliver the heat to approximately 6000 homes and businesses that are connected to that system

The datacenter in Høje Taastrup is a part of Microsoft data center Region DENMARK EAST that makes services like Microsoft Azure, Microsoft 365, and Dynamics 365 available with low latency and data stored locally in Denmark It is one of the first locations where Microsoft will supply surplus heat to the district heating network The new agreement has been made possible due to existing district heating infrastructure close to the datacenter as well as a strong partnership with VEKS and HTF.

Mikael Mikkelsen, Data Center Commercial Director at Microsoft, tells DDI: “It is essential for Microsoft to contribute to the green transition in our local communities. Microsoft has ambitious sustainability goals of being carbon negative, water positive, and have zero waste by 2030, and with the projected growth of data centers in coming years, it is essential that our data centers continue to set new standards for energy efficiency ”

VEKS estimates that not only will this project contribute to the local green transition by reducing emissions (by reusing energy compared to using nonrenewable energy sources) it will also bring savings to residents in the district heating area

Henrik Hansen, CEO of Danish Data Center Industry adds; “Data centers have the potential to play an important role in the green transition Projects such as this one are the future of district heating and an important step for increased grid connectivity in Denmark ”

The first deliveries of this new project are expected to reach residents during the 2025-2026 heating season The Microsoft data center in Høje Taastrup is still under construction. It is expected to open in the fall of 2025.

Microsoft has ambitious sustainability goals of being carbon negative, water positive, and having zero waste by 2030, and with the projected growth of data centers in coming years, it is essential that our data centers continue to set new standards for energy efficiency.

TheAIrevolutionrequires asteadyhandatthehelm

Powerful forces are at play

The AI revolution brings steep learning curves, immense opportunities, and significant risks for those who fail to navigate it carefully This was underscored at a well-attended networking event on 26 November, hosted by the Danish Data Center Industry and Legrand at Stamholmen in Hvidovre

“There’s a lot happening in the industry right now The development is incredible not only in terms of new projects but also in the influx of capital from new sources Our industry has become a true darling for investors,” said Henrik Hansen, CEO of the Danish Data Center Industry

“This opens many opportunities but also places a great responsibility on us as an industry We must work diligently to improve our energy efficiency, optimize our energy mix, and collaborate more closely with surrounding industries particularly utility companies. This will need to be a significant focus in the coming years.”

Henrik Hansen highlighted that recent projections from Energinet indicate a sixfold increase in electricity consumption by data centers over the next decade, primarily in Western Denmark, based on known projects

“These are staggering numbers We’re in close dialogue with authorities to expedite the development of green energy to meet the anticipated demand,” Hansen emphasized

“We’ve also provided direct input to the minister regarding our perspective on the AI strategy There’s a need for much greater awareness at the political level, and we all need to contribute to educating lawmakers about our industry,” he urged

Preparing for the AI Wave

Michael Esmann, BtB Manager at Legrand Data Center Solutions, posed a rhetorical question to the audience: “Is the industry ready for AI?”

“At Legrand, we are ready But what does that actually mean? For us, it’s about delivering the components that enable this, such as transformers, UPS systems, racks, and cooling systems,” Esmann explained. He also addressed the challenges posed by the rapid pace of AI development.

“For us, the main issue is production capacity for certain components Since the infamous ship blocked the Suez Canal, we’ve faced challenges Delivery times have improved from 30 weeks to 12, but that’s still too long to meet customer expectations,” Esmann admitted

Academic Insights

Assistant Professor Raghavendra Selvan from the Department of Computer Science at the University of Copenhagen shared insights into his research on measuring CO2 emissions from machine learning models

“Our primary focus has been on the direct energy consumption of AI usage Some language models train on 18 trillion data points and the numbers are growing exponentially,” Selvan noted

For example, training a single model like Llama 3 for medical analysis consumed 23,746 MWh of electricity. Selvan called on the industry to share analysis data for research purposes.

We must work diligently to improve our energy efficiency, optimize our energy mix, and collaborate more closely with surrounding industries particularly utility companies. This will need to be a significant focus in the coming years.

“It’s challenging to distinguish between traditional data centers and AI in terms of electricity consumption But energy production for data centers is becoming a bottleneck The growth is equivalent to adding another Sweden or even another Germany to the grid,” Selvan illustrated

Part of the solution could lie in ‘green scheduling,’ pushing computations to periods with lower CO2 footprints

“However, this must be done without compromising user experience If users get a response saying, ‘It’ll be windy in three hours check back then,’ they won’t accept that,” Raghavendra Selvan said

Unlocking the Potential of Waste Heat

Frederik Rugaard from Høje Taastrup District Heating shared insights into projects utilizing waste heat from data centers, including a collaboration with Nordea that saves 57 tons of CO2 annually while heating 700 households.

Similar initiatives with GlobalConnect and Microsoft are expanding this concept, but challenges remain, such as the regulated price cap on waste heat. Rugaard called for flexible regulations to maximize waste heat utilization

Innovation Must Accelerate

The event concluded with a panel debate on whether industry innovation can keep pace with AI development Alberto Ravagni, CEO of Net Zero Innovation Hub, stressed the need for a shift:

“AI development requires a new approach slow, continuous growth won’t suffice We need innovation, particularly collaborative innovation within the industry ” The discussion highlighted modular solutions, such as container-based systems, as a potential way to accelerate development

“When you work with ‘Lego bricks,’ you can test quickly and later modify the components inside the box,” Ravagni noted

The industry faces a rapidly evolving landscape, and collaboration, adaptability, and innovation will be critical to navigating the AI revolution effectively.
