EDF Power Solutions, NV Energy Sign 25-Year Agreement for 400 MW Solar and 1,600 MWh Storage Project
EDF power solutions North America has announced the execution of two 25-year Power Purchase Agreements (PPAs) with NV Energy, marking another significant step in the development of large-scale renewable energy and battery storage infrastructure in Nevada. The agreements cover the combined electricity output of the Winston Energy Project, a planned hybrid facility that will pair 400 megawatts alternating current (MWac) of solar generation with a 400 MW/1,600 megawatt-hour (MWh) battery energy storage system.
The Winston Energy Project is planned for private land in Lyon County, Nevada, and is expected to begin delivering electricity to NV Energy in October 2029. By combining utility-scale solar generation with long-duration battery storage capacity, the project is designed to provide renewable electricity while improving the flexibility and reliability of the power supplied to customers.
The agreements represent a long-term commitment between EDF power solutions North America and NV Energy and highlight the growing role of integrated solar-plus-storage projects in supporting the evolving electricity needs of Nevada. The project will contribute new renewable generation to the state while providing energy storage capacity that can help manage electricity supply beyond periods of peak solar production.
“We are delighted by our continued partnership with NV Energy and ability to contribute paired solar and storage solutions which provide efficient, sustainable, and reliable energy to its customers,” said Jacqueline de Fresart, Associate Director of Origination and Power Marketing at EDF power solutions North America. “We look forward to more opportunities together and to accelerate decarbonization in North America.”
Once operational, the Winston Energy Project is expected to generate approximately 1,110,000 megawatt-hours of renewable electricity each year. According to the companies, that annual generation would be sufficient to provide electricity for approximately 100,000 Nevada homes.
The project is also expected to deliver measurable environmental benefits. Its annual renewable generation is estimated to avoid carbon dioxide emissions equivalent to the emissions produced by more than 187,000 passenger vehicles driven for one year. The combination of renewable generation and battery storage is intended to support Nevada’s transition toward a lower-carbon electricity system while helping meet increasing demand for dependable power.
The development is expected to produce economic benefits for Lyon County and the surrounding community as well. During the peak construction period, the Winston Energy Project is expected to employ more than 400 workers. Construction activity will therefore create opportunities for local employment and businesses involved in areas such as construction, engineering, equipment supply, transportation and other project services.
Beyond the temporary employment generated during construction, the project is expected to contribute approximately $100 million in tax revenue to the local community over its operating life. Such revenues can provide a long-term economic contribution to the region and support public services and community priorities.
The planned facility also reflects a broader industry trend toward combining renewable generation with battery energy storage. Solar power provides a substantial source of electricity during periods of strong sunlight, while the integrated battery system can store energy for later use. This configuration can increase the usefulness of solar generation and help align renewable electricity production with periods when customers require power.
For utilities, solar-plus-storage projects can offer a way to expand renewable generation while also addressing some of the challenges associated with variable renewable resources. Battery storage can provide additional operational flexibility and allow stored electricity to be delivered when solar output declines, including during evening periods when electricity consumption can remain elevated.
The Winston Energy Project therefore forms part of the broader expansion of renewable energy infrastructure across the United States. Nevada, with its strong solar resources, has become an important market for utility-scale solar development, while the increasing deployment of energy storage is helping transform how renewable electricity is integrated into the power system.
For EDF power solutions North America, the agreement with NV Energy further expands its portfolio of renewable and energy storage projects and reinforces the company’s focus on delivering integrated energy solutions for utilities and other customers. The company has more than 35 years of experience in the renewable energy sector and has developed 26 gigawatts of wind, solar and storage projects in North America.
EDF power solutions North America works across multiple areas of the energy transition, including grid-scale renewable power, energy storage and electric vehicle charging infrastructure. Its approach is focused on developing projects that can support customers’ carbon-reduction objectives while addressing the need for reliable and scalable electricity supplies.
The company’s portfolio includes renewable generation and storage technologies intended to help meet changing energy requirements across North America. As electricity demand increases and utilities pursue cleaner generation resources, projects that combine renewable power with energy storage are expected to become increasingly important to the development of resilient power systems.
The Winston Energy Project is also expected to support NV Energy’s efforts to expand access to renewable electricity for its customers. Through the two 25-year PPAs, NV Energy will secure the project’s combined solar and battery output under long-term agreements, providing a framework for the development and operation of the facility.
The October 2029 target for initial electricity delivery provides a multi-year development and construction timeline for the project. During this period, the project will progress through the necessary development, engineering, procurement and construction activities before moving into commercial operation.
The project’s scale underscores the increasing importance of utility-scale renewable energy and storage as the electricity sector continues to evolve. A 400 MWac solar facility paired with a 400 MW battery system represents a substantial investment in clean energy infrastructure and demonstrates how generation and storage can be developed together rather than as separate resources.
With its expected annual renewable generation, significant battery capacity, construction employment and projected tax contributions, the Winston Energy Project is positioned to provide environmental, economic and energy benefits to Nevada. Its long-term agreement with NV Energy also demonstrates the continued development of partnerships between utilities and renewable energy developers to bring large-scale clean energy projects to market.
EDF power solutions North America said it remains committed to developing solutions that address customers’ carbon-reduction goals while supporting reliable energy supplies. The company views its continued work with NV Energy as an opportunity to expand the use of paired solar and storage resources and contribute to the broader decarbonization of the North American energy sector.
As the Winston Energy Project advances toward its planned 2029 delivery date, the development will represent another major addition to Nevada’s renewable energy infrastructure and demonstrate the growing role of solar-plus-storage projects in the region’s future power supply.
