United States-based grid-scale storage company Peak Energy Technologies will establish a sodium-ion battery energy storage manufacturing facility in Sacramento, California. Planned for Metro Air Park, the 183,000 sq ft plant will be capable of producing as much as 4 GWh of battery systems each year. Peak Energy expects to invest up to $71 million in the facility and create 239 local positions over the next 18 months, with average yearly pay exceeding $90,000.

The facility will produce passively cooled sodium-ion battery energy storage systems for grid-scale applications. Peak Energy expects production and shipments to begin in Q1 2027. The company said its systems are designed to reduce energy storage costs by 20%, provide 99% guaranteed uptime, and operate for more than 20 years without scheduled maintenance.

Peak Energy has more than 6 GWh of customer commitments already in place. Its customer agreements include Jupiter Power, Energy Vault, and RWE Americas. The company has also formed a strategic partnership with General Motors, including investment from GM Ventures, to pair GM’s sodium-ion cell technology with Peak Energy’s storage platform.

Following a search across the country, Peak Energy selected Sacramento as the preferred site. The company has based its decision on the region’s manufacturing workforce, closeness to California’s energy storage market, and backing from state and local partners. Support includes a $10.5 million CalCompetes tax credit awarded in May 2026, while the Greater Sacramento Economic Council assisted in coordinating workforce, utility, and economic development agencies.

Peak Energy was founded in 2023 and has secured more than $1 billion in commercial agreements. The company’s team includes personnel with experience at Tesla, Enovix, and Fluence. Its California expansion is expected to create 348 net new jobs across Sacramento and Burlingame by 2030.
