We develop and deliver renewable energy projects that support the United States’ transition to a more resilient and secure energy future. Our work goes beyond generating clean power—we create lasting value by driving economic growth, strengthening local communities, and promoting long-term environmental stewardship. By harnessing wind, solar, and other renewable resources, we provide reliable, domestically produced energy while advancing innovation, efficiency, and sustainability.
Our projects are built to deliver tangible benefits at the local level. We prioritize working with regional partners and supply chains to create high-quality jobs, support American workers, and contribute to the economic vitality of the communities where we operate.
Recognized since 2015 as one of the world’s greenest energy companies, we operate across 24 countries and six renewable technologies, supporting organizations across the U.S. in decarbonizing and optimizing energy use.
Our approach combines advanced technologies, integrated delivery capabilities, and collaborative partnerships with local stakeholders. From development and financing to construction, operation, and maintenance, we manage projects across the full lifecycle.
Guided by our commitment to sustainability, innovation, and community, we ensure that the benefits of clean energy extend well beyond the grid—supporting resilient communities, expanding opportunities for American workers, and building a more sustainable future for generations to come.
ACCIONA Energía is one of the world’s leading wind energy operators, with more than three decades of experience developing and operating wind projects. Since pioneering early wind power development in the 1990s, the company has built a strong track record of delivering reliable, utility-scale renewable energy across global markets.
In the United States, ACCIONA Energía has established a significant presence through the development, construction, and operation of large-scale wind projects, including the Tatanka Wind Farm in the Dakotas—one of the largest wind farms in the country at the time of its commissioning. This project reflects our long-standing commitment to delivering high-quality renewable energy infrastructure in the U.S.
Today, we continue to apply our global expertise to support domestic energy production, strengthen local economies, and create skilled jobs in the communities where we operate.
ACCIONA Energía brings decades of global renewable energy experience to the photovoltaic solar sector, delivering projects that combine performance, reliability, and long-term value. The company has been actively involved in the evolution of solar energy, supporting its growth into a key pillar of today’s energy mix.
In the United States, ACCIONA Energía has developed and operated large-scale solar projects that demonstrate its ability to deliver efficient, utility-scale generation tailored to local market needs. Building on early involvement in pioneering projects such as Nevada Solar One, the company has expanded its photovoltaic footprint with modern installations that leverage advanced technologies and optimized design.
Through its solar activities, ACCIONA Energía continues to support domestic energy production while contributing to local economic development and job creation, reinforcing its commitment to the communities where it operates.
ACCIONA Energía is building experience in battery energy storage systems (BESS) as part of its broader approach to supporting a more flexible and resilient energy system. By integrating storage with renewable generation, battery solutions can help manage variability, improve efficiency, and enhance overall grid performance.
In the United States, ACCIONA Energía’s experience includes the Cunningham Battery Energy Storage System in Texas, a 190 MW / 380 MWh facility and one of the largest projects of its kind on the ERCOT grid. This project reflects the company’s capability to deliver utility-scale storage solutions that support grid stability and energy reliability, particularly during periods of peak demand.
ACCIONA Energía continues to assess opportunities for energy storage that complement its renewable portfolio, responding to evolving market conditions and grid needs. Through this approach, the company contributes to strengthening domestic energy infrastructure while supporting local economic activity and jobs in the communities where it operates.
ACCIONA Energía's largest photovoltaic plant globally has begun supplying renewable energy to Texas, the heart of the U.S. oil industry.
ACCIONA ENERGÍA Is involved in the biggest photovoltaic challenge in its 30 years’ experience in the renewables sector: building solar plants in the United States consisting of more than two million solar panels on a total surface area equivalent to more than 1,600 football fields.
