Summary

The announcement marks the latest in a string of sodium battery developments as utilities and customers look for new sources of grid-tied and behind-the-meter capacity. Other recent sodium-ion battery developments came from Colorado-based Peak Energy. Late last year, Peak said it would deliver up to 4.75 GWh of its sodium-based batteries by 2030 to an independent power producer, Jupiter Power. In June, Peak announced a manufacturing and design partnership to support General Motors’ stationary storage aspirations, saying it would build a 4-GWh manufacturing plant in Sacramento, California.
