In addition to 100 MW of battery-based energy storage that Southern California Edison (SCE) will procure from AES Corporation, SCE has also awarded 20-year contracts for AES to provide 1,284 MW of combined cycle gas-fired generation.
This new capacity will be built at AES’s existing power plant sites in Huntington Beach and Long Beach, Calif.
These awards come as a result of SCE seeking a variety of new generating resources and creative energy solutions to replace the retired San Onofre Nuclear Generating Station and a number of older natural gas-fired power plants that are expected to retire in the near future to comply with California’s policy on the use of ocean water for cooling.
For the gas-fired capacity, financing agreements are expected to be finalized in 2016, construction is expected to begin in 2017 and commercial operation is scheduled for 2020. For the energy storage capacity, commercial operation is scheduled for 2021.
