An ex-project finance banker and former NRG Energy finance official has joined a utility-scale battery storage developer as cfo.
The official, Krish Koomar, left his role as vice president and assistant treasurer at NRG last year and joined esVolta in Orange County, Calif., this year, according to his LinkedIn profile.
The start-up, backed by Australian asset manager Blue Sky Alternative Investments, develops, owns and operates storage projects across North America. Its portfolio of operational and contracted projects totals 450 MWh.
Before joining esVolta, Koomar had worked in finance and treasury departments at NRG Energy, Edison Mission Energy and InterGen.
He is also an ex-WestLB banker, having originated and structured energy project finance transactions out of the firm's Houston office from 2007 to 2008. He began his career at The Williams Companies and then Shell Trading.
His latest employer, esVolta, is in the process of developing the 75 MW/300 MWh Hummingbird lithium-ion battery storage project in Coyote Valley, Calif.
The project is due to begin operations by 2020 to replace generation that Pacific Gas & Electric receives from Calpine's 605 MW Metcalf Energy Center gas-fired plant, which had filed to withdraw from the CAISO market due to poor economics but has continued running under an above-market reliability-must-run contract.
The contract for Hummingbird is one of several that emerged from a subsequent request for proposals that PG&E conducted at the behest of the California Public Utility Commission.
