Commercial energy storage solutions provider Stem Inc has won out in a competitive Request for Proposals (RFP) to manage a 345MWh fleet of commercial and municipal energy storage systems in Los Angeles, California.
The company said last week that it has been contracted to operate 87 systems using its Athena advanced artificial intelligence software platform, including 25 at newly acquired customer sites, by SK E&S and SUSI Partners. SK E&S is a South Korea-headquartered power provider which has mostly focused on generating electricity from liquid natural gas (LNG) plants. Meanwhile Switzerland-headquartered sustainable infrastructure investment manager SUSI Partners is likely a familiar name to readers of this site for its energy storage activities in key markets including Ontario, Canada. In April 2019, Energy-Storage.news reported that SUSI Partners had acquired a 50% stake in a 340MWh portfolio of California commercial and municipal energy storage projects developed by Advanced Microgrid Solutions from owner Macquarie. This site has made enquiries as to whether this deal, which at the time was cited as 60MW/340MWh across 90 projects, refers to the same portfolio Stem will now be managing.
SK E&S is latterly rolling out a clean energy business, including solar power and fuel cell technology. SK E&S CEO Daejeon Choi said that Stem Inc had been evaluated alongside other companies in a “highly competitive RFP process” and “stood out”.
“We were extremely impressed with the company’s technical and operational capabilities as well as the superiority of its software and services solution,” SK E&S CEO Daejeon Choi said.
The multinational pair are partners in owning the 345MWh energy storage portfolio in LA, which all sits in the service area of investor-owned utility (IOU) Southern California Edison (SCE). SCE is one of three major IOUs in California and was therefore bound by mandate AB2514 to procure a large amount of energy storage by the start of this decade, which in many ways kickstarted the ongoing mainstreaming of energy storage.
