Peak Energy announced it will establish a grid-scale sodium-ion energy storage manufacturing facility in Sacramento, California. The company has chosen a 183,000-ft2 facility in Metro Air Park that should accommodate a 4-GWh annual manufacturing capacity.
With more than 6 GWh of customer commitments already in place, Peak expects to enter production and begin shipments in Q1 2027.
“America needs energy storage that is lower cost, more affordable, more reliable and purpose-built to meet the demand coming onto the grid,” said Landon Mossburg, CEO and Co-founder of Peak Energy. “This facility is proof that America can lead not only in inventing the technology, but in building it at scale. With our manufacturing facility in Sacramento, we’re enabling American energy innovation to lower electric bills while creating high quality jobs.”
Peak Energy will invest $71 million into the Sacramento site and create 239 new local jobs. Peak chose Sacramento following a competitive nationwide site selection process, citing the region’s manufacturing talent, proximity to California’s growing energy storage market, strong state and local support and the Greater Sacramento Economic Council’s leadership in bringing together workforce, utility and economic development partners. Peak’s growth in California is supported by a $10.5 million CalCompetes tax credit, which was awarded in May 2026.
Peak plans to commercialize the first fully passive grid-scale energy storage system, engineered to operate for more than 20 years without scheduled maintenance and designed as a drop-in replacement for today’s battery energy storage systems. In California alone, eliminating battery refrigeration costs could save ratepayers an average of $100 million annually, Peak says, while helping lower the overall cost of energy storage and deliver more affordable electricity.
To date, Peak has secured customer agreements with Jupiter Power, Energy Vault and RWE Americas and recently announced a strategic partnership with General Motors, including an investment from GM Ventures, to pair GM’s next-generation sodium-ion cell technology with Peak’s proprietary energy storage platform.
