WHO WE ARE
Sonnedix is an international renewable energy producer with over 15 years of sustainable growth. We develop, build, and operate renewable energy projects for the long-term, with a focus on providing green, affordable electricity to our customers, and acting as a true social citizen where we operate.
The Sonnedix Group is majority owned by a fund of institutional investors.
Powering a Bright Future
Clean energy’s potential to transform daily life drives and inspires us to build renewable power plants for the long term. We use the most current technologies available and work with partners that share our commitment to producing a continuous, reliable, and efficient supply of green and affordable electricity to our customers.
Key Player in the Energy Transition
We are constantly evaluating multiple regulatory regimes at different phases of integration in the renewable energy market, to uncover new opportunities that allows us to provide reliable and efficient clean energy and sustainable solutions for the world we want to live in.
Diverse and Inclusive workplace
We are working to become a truly diverse and inclusive organisation. We promote a culture of listening to each other, educating ourselves, and implementing changes to improve our workplace. We want to ensure every member of our One Team feels and knows they belong.




GROWTH
WHAT WE DO
We are supporting and accelerating our sustainable growth strategy by combining a wide range of activities. We continue to add new projects (operational or in different development stages) to our portfolio, and develop partnerships with like-minded players within the renewable energy sector. Our Growth team performs project development - identifying, evaluating and de-risking all aspects of potential projects. They work with developers, brokers and relevant permitting bodies, landowners, and internal functional teams to bring our projects to a readyto-build stage. This includes the acquisition of operational assets, and strategic transactions that can allow us to further expand and enter into new OECD markets and/or develop new capabilities and technologies.
ASSET MANAGEMENT (AM) AND OPERATIONS & MAINTENANCE (O&M)
We conduct regular analyses and site visits to identify solutions that can ensure the plant’s optimal running. We work closely with O&M (Operations and Maintenance) in-house or external teams, as well as other local stakeholders. O&M teams are responsible for timely maintenance and repairs to reduce energy losses at our sites. A central Remote Operations Intelligence team takes care of monitoring, data analytics, and forecasting activities for our global portfolio.
PROJECT FINANCING
We organise debt and other non-recourse financing for newly developed or acquired projects. We also optimise financing for the company’s existing project portfolios. We work closely with lenders, investors and advisors, ensuring Sonnedix’s assets fulfil their required cash yields and rates of return over the long term.
POWER MARKETING
We manage energy price and volume risk exposure globally. We lead the strategy, origination, and execution of Power Purchase Agreements (PPAs), hedge transactions, and other off-take agreements across all our development projects.
ENGINEERING & CONSTRUCTION
02
Our team of engineers, PV designers, storage experts and project managers manage the construction process of our plants. We make sure we stay up to date on technical and technological trends, local codes, rules and regulations, and overall region-specific construction costs.
A GROWING GLOBAL PLATFORM
Sonnedix currently has over 500 power plants in operation, construction or different phases of development across ten countries. We aim to grow sustainably and create value by leveraging our prudent capital structure and sponsorship, and investing in high-quality assets with predictable cash flows. We are also continuously building and executing upon a pipeline of new projects and M&A opportunities.

ENVIRONMENTAL, SOCIAL, AND GOVERNANCE (ESG)
Integrating responsible, forward-thinking corporate policies into our daily business practices is key to us achieving our goal of providing green, affordable electricity to our customers. It’s what allows us to behave sustainably, ethically and accountably as we develop, build, and operate renewable projects around the world. It’s also what ensures that we have a positive impact on our people, environments, and communities where we work.
We focus our corporate policies on three specific areas:
Environmental Social Governance
Protect, enhance, and care for the environments where we build and operate our plants.
Support the communities we work in with social and developmental activities, job opportunities, and essential provisions.
MARKET LEADER IN ESG

Ensure our employees and partners are committed to integrity in action, fairness in conduct, and respect for all.

Our efforts have had an impact with GRESB (Global Real Estate Sustainability Benchmark), an independent, investor-driven organisation, committed to assessing the ESG performance of real assets globally, awarding Sonnedix Infrastructure Sector Leader for 2024.
