Energy Solutions for the Grid

The future of power is here. Today.

Over the next decade and beyond, power sources and utility providers such as yours will be required to achieve dramatic, and at times formidable, improvements to satisfy increasingly demanding industry standards and practices. At the same time, consumer demand for more effective, efficient and environmentally conscious utilities continues to drive research and development to transform and transition the power utility marketplace, and the grid as a whole.

and actions of all users connected to it – generators, consumers and those that do both – in order to ensure an economically efficient, sustainable power system with low losses and high levels of quality and security of supply and safety.”

Due to environmental concerns, the recent trend towards environmentally friendly and green-energy generation, coupled with the general need to improve efficiency without decreasing reliability of electricity distribution, there will be an increase in the interconnections between geographical regions, and a rapid rise in the number of distributed generation plants.

As a result, several applications for smart solutions continue to emerge in the everevolving grid ecosystem, where the market is being driven by an insatiable and irreversible demand for reliable, available and clean power.

To meet these emerging challenges, innovative systems such as intelligent monitoring and control are being developed to create a smart grid, defined by the European Union as, “an electricity network that can cost-efficiently integrate the behavior

Maxwell’s proven high-voltage products are already deeply embedded in the grid – where they have worked diligently and intelligently to achieve smart results for the past century. And our innovative ultracapacitor technology is at the very forefront of the exciting new developments that are helping to shape the future of the smart grid.

How Ultracapacitors Work PRIMARY ENERGY SOURCES, like internal combustion engines and fuel cells, work well as a continuous source of low power. However, they cannot efficiently handle peak power demands or recapture energy in today’s applications because they discharge and recharge slowly.







ULTRACAPACITORS deliver quick bursts of energy during peak power demands, then quickly store energy and capture excess power that is otherwise lost. They efficiently complement a primary energy source in today’s applications because they discharge and recharge quickly. In addition to enabling increased energy efficiency, they help customers reduce emissions and lower costs.

Ultracapacitors = Ultra availability for Grid Energy Storage Maxwell ultracapacitor products are uniquely suited to deliver excellent cost-of-ownership value by providing a long service life and excellent reliability.* Within the context of a hybrid ultracapacitorplus-battery energy storage solution, ultracapacitors perform fast response functions and extend battery performance, efficiency and operational life. Combining the power of ultracapacitors with the energy of batteries provides superior performance, operating range and life. It also dramatically increases the overall performance and safety of your grid system and overall organization. Ultracapacitors ease or eliminate the need to overhaul your grid infrastructure on a regular basis.

Today, ultracapacitor energy storage provides a wide range of benefits to independent energy generators and utilities alike including traditional fuel energy generation and renewable generation such as solar and wind.

Renewable generation applications may include: • Wind Pitch Control • Frequency Regulation • Voltage Control and Power Quality • Renewables Capacity Firming/Ramping • Peak Shaving and Load Leveling • Spinning Reserve

Change is in the wind.

Trust in the wind. Trust in Maxwell. Utility providers want to know that their equipment is not only reliable, but also long-lasting. When it comes to questions of real change today – and well into the future – many real answers can be found blowing in the wind. The benefits of wind pitch control systems are many, and include reduced maintenance, greater reliability and fail-safe operation. The value derived from wind pitch control systems is not just immediate, it is longlasting. Not only do they boost power and provide fail-safe backup power, but they reduce the total cost of ownership over the life of a wind turbine. Ultracapacitors have been used in wind turbines since 1999, and more than 30,000 turbines across the world rely on ultracapacitors to maintain peak performance and longevity. In fact, ultracapacitors can dramatically reduce battery-related costs over the life of a turbine (including replacement, maintenance and downtime).

In the years since, we’ve continued to refine our insight and expertise in wind pitch control systems. And we look forward to even more growth and development to come.

When the sun takes a break, Maxwell goes to work.

Solar and wind firming and ramp rate control solutions. Solar and wind firming and ramp rate control are equally impactful, and invaluable solutions to employ on the grid. Solar and wind firming and ramp rate control provide increased power quality from intermittent renewable resources. Added value comes in the increased ability to add even more renewable assets to the grid, thereby complying with legislative mandates and incentives. Of course, with great opportunity comes great challenge. As an increased amount of intermittent solar and wind renewable energy penetrates the grid, output becomes increasingly unstable. And handling this increased intermittency can lead to a spike in peak power reserves along with an increased capacity charge for the ratepayer.

Maxwell was recently awarded a project by the California Energy Commission to address this exact issue, demonstrating an energy storage system that showcased the capability of ultracapacitors to fill in short-term solar power intermittencies and provide ramp rate control for longer intermittencies. A more detailed case study can be found on our website at

By the wayside.

When talk turns to something “falling by the wayside,” it’s not often that a very positive conversation ensues. But when it comes to wayside rail brake energy recovery, power stabilization and frequency regulation, there are a wide range of positive charges an organization and grid provider can plug into. The benefits of wayside rail brake energy recovery, power stabilization and frequency regulation are many, and include reduced grid-energy consumption. Immediate and enduring values of implementing these practices include lower electricity charges to customers and grid upgrade cost deferral for the utility provider. In other words, you’ll be able to get more mileage out of your existing grid structure even when more customers are using your rail services. And your satisfied and everincreasing customer base will have to pay less to use those services. Talk about a win-win.

Maxwell recently joined forces with ABB for a project at the Southeastern Pennsylvania Transportation Authority (SEPTA) to help the time-honored transit authority recover lost braking energy – and thereby reduce system-wide energy consumption. The development and implementation of a hybrid ultracapacitor-battery storage system allowed SEPTA to recycle the braking energy from many of its trains, optimize the use of their energy storage and decrease the payback period for their equipment among many other benefits. In fact, the cooperative effort resulted in a 10-20% reduction in SEPTA rail vehicles’ consumption of grid-supplied electrical energy. You can read more about this compelling case study on our website at

We put the new in renewables.

Maxwell ultracapacitor energy storage delivers a wealth of benefits to independent energy generators and utilities that make the move to implement our resource- and cost-efficient ultracapacitor technology. This is especially true when it comes to renewable generation applications such as solar and wind.

Renewable generation applications on the grid today may include: • Wind Pitch Control • Frequency Regulation • Voltage Control and Power Quality • Renewables Capacity Firming/Ramping • Peak Shaving and Load Leveling • Spinning Reserve

From reduced maintenance and lower total cost of wind turbine ownership in wind pitch control applications to a reduction in both fuel consumption and emissions in peak shaving and load leveling applications, implementation of our ultracapacitors will continually renew your confidence and investment in renewable generation applications.

Traditional values.

Renewables aren’t the only generation applications that stand to benefit from the implementation of Maxwell ultracapacitor energy storage solutions. Traditional fuel energy generation applications, such as combustion turbine and diesel generators, can also expand their power bases with our help. Genset starting with ultracapacitors mitigates battery failure during startup and lowers the total cost of ownership. Ultracapacitor usage as spinning reserves reduces fuel consumption, operating costs and the need for traditional peaker plants. Frequency regulation with ultracapacitors also reduces fuel consumption and operating costs, and lessens the overall dependence on traditional generation resources.

These are just some of the many ways that Maxwell’s ultracapacitors help energy generators, utilities and grid providers restore faith in traditional values – and kick-start entirely new traditions on the grid.

CONDIS high-voltage products. 速

Generation. Distribution. Transmission. At Maxwell, our high-voltage products have been helping define and drive the grid for the past century. We classify our renowned CONDIS ÂŽ products into three distinct categories and classifications. Generation. Distribution. Transmission. The following is a closer look at each category and the Maxwell CONDIS products contained within.

Power Generation and Voltage Transformation: CONDIS high- and medium-voltage capacitors serve as key components in multiple applications for electrical power generation systems and their local substations.

Electrical substations, which transform voltage from high to low (or the reverse), must sustain severe voltage conditions. CONDIS high-voltage grading capacitors enable multi-chamber circuit breakers to equalize voltage distribution across the breaking-unit during normal and fault switching operations. CONDIS transient recovery voltage (TRV) capacitors enable circuit breakers to raise switching power, and CONDIS capacitive voltage dividers (CVDs) used in capacitive voltage transformers (CVTs) enable voltage measurement of high-voltage overhead lines within the electrical substation.

In the field of power generation, CONDIS coupling capacitors are used in partial discharge (PD) measurement systems sensors to evaluate the condition of generators’ insulation systems. CONDIS high-voltage capacitors are a dependable choice for network operators seeking to improve the efficiency of their electrical power generation and voltage transformation systems.

Grid stability. Grid reliability.

Integration of Distributed Power Grids: The shift from centralized power grids to distributed power grids is creating new challenges for electric utilities at the distribution level. Power generation from renewable energies must now be integrated into systems that were primarily designed for larger and more predictable power plants – such as nuclear or coal power plants. To guarantee the stability of such distributed power grids, the main challenge will play out at the boundary (or “grid edge”) and on the mid-voltage existing network of traditional stable and well-understood territories. CONDIS high- and medium-voltage products are placed at these boundaries, or grid edges, for metering or power line communication (PLC) systems. Coupling capacitors for PLC applications are used with onboard electronics, where the supply of distributed generation (such as solar and wind plants) into the grid can be disconnected by the network utility for

maintenance and repair without introducing risks to grid stability. The PLC couplers are additionally used for broadband power line communication for smart grid deployment and enable data transmission rates of up to 30 mbps for network communication. As an added advantage, CONDIS damped voltage dividers are part of lightning overvoltage monitoring systems, which monitor the grid to improve power quality in smart grid systems. Reliability, high electrical performance and resilience in extreme temperature (Arctic Technology) environments are the main features of CONDIS products, providing our customers with first-class capacitors in the power grid market.

in wider networks at a continental or intercontinental scale. The reliability of the transmission lines and their ability to deliver high-quality power are major challenges in the operation and development of networks. In the field of power transformation, Maxwell’s CONDIS capacitors improve power quality and guarantee reliable AC/DC conversion.** CONDIS capacitors are key components in many different applications, such as circuit breakers, voltage metering and PLC systems.

High-voltage transmission lines transport electrical energy – from large power generation plants to the substations linking

In high-voltage direct current (HVDC) power transmission, CONDIS capacitors filter high frequency harmonics due to power electronic converters, and therefore improve power quality of the transmission line. CONDIS dry MV capacitors are used in HVDC converter stations as thyristor valve capacitors for reliable function of the HVDC conversion.

these lines to the medium-voltage distribution system. Operating in either AC or DC, highvoltage transmission lines are interconnected

High-Voltage Transmission Lines:

Flexible. Reliable. Solutions.

Emerging energy storage solutions and products must fit seamlessly into the equally conservative and conscious environment of the energy marketplace. Energy storage products and infrastructures must provide multiple solutions and serve as truly flexible and dynamic resources. They must provide power where and when it is needed. At any and all times. That’s where Maxwell and our industryleading ultracapacitor and high-voltage products plug in. Maxwell ultracapacitor products have been meticulously and brilliantly designed to increase efficiency and reliability across all areas of the grid.
