Avangrid Renewables’ thermal generation consists of two natural gas-fired plants in Klamath Fall, Oregon totaling more than 600 megawatts of generation: the award-winning Klamath Cogeneration facility and its companion Klamath Peaking plant.

Avangrid Renewables worked closely with the City of Klamath Falls to develop the 506 MW Klamath Cogeneration Plant, one of the most energy-efficient advanced gas-fired power plants in the West. When commissioned in 2001, Klamath became the cleanest fossil-fueled power plant ever constructed in the US in terms of greenhouse gas emissions. In addition, Klamath uses up to 3 million gallons per day of treated municipal wastewater provided by the City to meet 100% of its cooling needs.

The highly flexible 100 MW Klamath Peaking plant was added adjacent to the Cogeneration Plant to provide Avangrid Renewables customers with additional capability to meet peak summer and winter power needs.
