NRG Subsidiaries

NRG Energy is a Fortune 500 and S&P 500 Company that owns and operates one of the country’s largest and most diverse power generation portfolios. Our power plants provide more than 24,000 megawatts of generation capacity and include nuclear, wind, solar, natural gas and coal. In addition to our generation assets, we own and operate the below subsidiary companies:

Nuclear Innovation North America (NINA) is a partnership between NRG (88%) and Toshiba (12%) focused on developing new nuclear expansion projects using Advanced Boiling Water Reactor (ABWR)—the only advanced nuclear technology certified by the Nuclear Regulatory Commission that has been built on time and on budget.




NRG Bluewater Wind is our offshore wind energy development company. Bluewater finds the best locations for building and operating clean, reliable offshore wind farms. Offshore wind has tremendous potential in North America’s coastal regions, where energy demand is high and on-shore wind sites are scarce.

NRG Energy Services is a sole-source provider for engine maintenance and parts, serving municipal, institutional and industrial power customers—including utilities, universities, landfills, offshore platforms and U.S. military bases.

NRG Solar is NRG’s subsidiary company responsible for developing, constructing, financing and operating a multi-technology portfolio of solar power assets in North America. NRG Solar owns the Blythe solar facility, California’s largest photovoltaic power plant, and is building commercial-scale solar thermal generation at sites in California and New Mexico.

NRG Thermal is one of the largest third-party steam providers in the United States, operating downtown heating and cooling systems in cities such as Pittsburgh, San Diego, San Francisco and Harrisburg, Pennsylvania. NRG Thermal is also pioneering a Combined Heat and Power Plus (CHP Plus) program that integrates conventional, proven energy sources and leverages them with leading efficiency and environmental technologies.

Reliant Energy is NRG’s retail electricity business, providing electricity and energy related products to more than 1.6 million customers in Texas. These customers range from homes and small businesses to the largest commercial, industrial and institutional clients in the state. The company is known for its high-quality customer care and commitment to delivering innovative products and competitive pricing.
