Glendale Water & Power has received approval from the Glendale City Council to repower the aging Grayson Power Plant with a combination of approximately 260 megawatts of renewable energy sources, energy storage and a limited amount of thermal generation. The decision comes after GWP was directed by the Council in April 2018 to re-evaluate the energy sector and find viable clean alternatives to its original proposal, which consisted primarily of thermal generation with battery storage.
Most of the facilities at the Grayson Power Plant, located at 800 Air Way, Glendale, Calif., were completed between 1941 and 1971—all except Unit 9 and the only one that will not be demolished.
The approved project’s capacity consists of:
- a 75-megawatt, 300 megawatt-hours battery energy storage system
- 50 megawatts of distributed energy sources that include solar photovoltaic systems and energy efficiency and demand response programs
- 93 megawatts of thermal generation from up to five internal combustion engines.
GWP’s announcement follows General Electric Co.’s announcement to demolish The Inland Empire Energy Center, a 750-megawatt gas-fired power plant, which has become too expensive to operate and maintain.
