🔋Tokyo’s Tepco to Test Stem and Sunverge Behind-the-Meter Batteries as Virtual Power Plants.
Sunverge and Stem, two California-based behind-the-meter battery startups, have landed their first international projects in Japan, joining mutual investor Mitsui in a series of virtual power plant projects for massive utility Tokyo Electric Power Co.
The projects, announced Monday, are relatively small-scale, considering Tepco’s scale as Japan’s biggest utility.
Stem’s Tepco project will involve three commercial-industrial building sites with about 750 kilowatt-hours of battery capacity, one of which, a recycling center in the Tokyo suburb of Yoshikawa, started operations two weeks ago, Stem CEO John Carrington said in a Tuesday interview.
