Solar Electric Solutions, a solar project developer, and its affiliate second-life battery company B2U have completed installation of a 1.2 MWh pilot stationary energy storage system using 200 Nissan Leaf batteries. Final target capacity is 17 MWh and will use 2,000 batteries. The battery system is paired with a 8.5 MW solar facility and will provide firm capacity, arbitrage, and ancillary services to Southern California Edison. This is both companies' first second-life battery project. With its low-value LMO cathodes not meriting recycling and large sales volumes, Nissan Leaf batteries are a common second-life battery. Clients should expect second life to play a niche role, especially as more recycling options become available.
