Key ESS product will get a first-time test with PGE

ESS says it will deploy an Energy Center — the utility-scale energy-storage product that it’s banking on to drive growth — for the first time in a demonstration project with Portland General Electric. ESS (NYSE: GWH) raised $246 million in a SPAC IPO in October based on a promising long-duration storage technology developed over the course of 10 years, but with virtually no revenue. In filings, the company has said it would use the proceeds from going public to speed deployment of the Energy Center, which it called “core to our long-term growth plan.”
