640 MWh of Mitsubishi and Powin energy storage is being retrofit to two California solar projects
Southern Power will use Mitsubishi Power Americas and Powin’s energy storage systems for two California projects totaling 640 MWh. The systems with a duration of 4 hours will be placed in the same location as already installed solar energy projects. They probably represent some of the largest solar energy + storage retrofits to date in North America.
The 205 MW Garland Solar Facility in Kern County will add 88 MW (352 MWh) of energy storage, and the 204 MW Tranquility Solar Facility in Fresno County will add 72 MW (288 MWh) of storage. Both additions to energy storage must be completed by the end of 2021.
The energy storage projects will be owned in partnership with AIP Management and Global Atlantic Financial Group, both of which have existing ownership interests in the Garland and Tranquility solar plants that went into commercial operation in 2016. Southern Power will manage the solar energy projects and will be responsible for operating the energy storage projects upon completion.
Geoff Brown, CEO of Powin, said: “We are delighted to continue our relationship with Mitsubishi Power and have been selected by Southern Power as a trusted partner to provide BESS for the long term for the Garland and Tranquility projects. This award underlines the fact that large-scale solar photovoltaic energy in combination with energy storage is cost-competitive. ”
Tom Cornell, Senior Vice President of Mitsubishi Power’s NEXT said, “Mitsubishi Power is delighted to leverage our network of capabilities in the Americas and globally to bring low-carbon solutions to Southern Power. These battery energy storage projects, which utilize lithium iron phosphate technology, are part of our vision to provide short- and long-term energy storage solutions that encompass lithium ion, hydrogen and other emerging storage technologies. “
