Mitsubishi Power and Powin LLC are partnering up for the development of two battery energy storage systems (BESS); that, together will have a capacity of 640 megawatt-hours. Both projects will enhance California’s grid reliability with additional flexible resource capacity for integrating intermittent renewable energy into the grid.
Firstly, the teaming up became a reality after the Southern Power awarded both companies with the contracts for the projects. The BESS are among the first collocated solar and storage projects in California; they are also among the largest retrofits of solar and storage in North America to date.
Secondly, the BESS are designed to have a 20-year life cycle and around four hours pf energy storage duration. Two solar facilities of Southern Power will receive the extra power from these projects. These are the 205 MW Garland Solar Facility in Kern County; as well as the 204 MW Tranquility Solar Facility in Fresno County.
Thirdly these projects will receive 88 MW and 352MWh of energy storage; and 72 MW and 288 MWh respectively. Both projects are scheduled to come online in 2021. The BESS developed by Mitsubishi Power and Powin will be owned by AIP Management and also Global Atlantic Financial Group.
Moreover, Southern Power will continue to operate them, as it has been doing since they began commercial operations in 2016. The company will also be responsible for operating the energy storage projects upon completion.

Mitsubishi Power to add lithium iron phosphate to BESS projects
Consequently, these two energy storage projects align with Southern Power’s growth strategy of developing and acquiring projects covered by long-term contracts with strong credit counterparties.
In addition, Tom Cornell, Senior VP of Mitsubishi Power’s NEXT said. “Mitsubishi Power is excited to leverage our network of capabilities in the Americas and globally to bring low carbon solutions to Southern Power.”
He also added. “These battery storage projects will use lithium iron phosphate technology, fit within our vision to provide short- and long-term energy storage solutions that include lithium ion; also, hydrogen, and other emerging storage technologies.”
Finally, Geoff Brown, CEO of Powin, said. “This award highlights the fact that large-scale solar PV paired with energy storage is cost competitive. We also applaud Southern Power for taking this step toward helping California meet its clean energy goals with energy storage.”
