Sodium-ion Battery plant Sacramento is moving from plan to reality as Peak Energy prepares to open a new grid storage factory in Metro Air Park. The company announced the project on July 8, 2026, alongside Sacramento leaders and local partners. Moreover, Peak Energy says the site will become the first sodium-ion battery manufacturing plant of its kind in the United States. The factory will support low-cost, large-scale grid storage and strengthen energy reliability across California and beyond.
Sodium-Ion Battery Plant Sacramento Brings Major Investment
Peak Energy plans to invest more than $70 million in the Sacramento County project. In addition, the facility is expected to generate seven-figure tax revenue and create about 240 new jobs. Local leaders see the plant as a major win for the regional economy. They also view it as another sign that Sacramento continues to grow as a clean energy hub.
Congresswoman Doris Matsui said the region is taking another big step toward becoming the clean energy capital of America. Likewise, Barry Broome of the Greater Sacramento Economic Council said the project supports climate goals while expanding advanced manufacturing in the area. As a result, the new factory could bring both economic growth and energy innovation to the region.
Why Peak Energy Chose the Sodium-Ion Battery Plant Sacramento Site
Peak Energy searched across the country before choosing Sacramento. The company selected Metro Air Park for several practical reasons. First, Sacramento sits close to Silicon Valley, where Peak Energy was founded. Second, the region offers a strong pool of skilled workers. Third, the site gives the company easy access to utility customers and major infrastructure.
Cameron Dales, co-founder of Peak Energy, said the company will launch its first gigafactory in Sacramento. He explained that the site will produce four gigawatt-hours of large-scale grid batteries each year. Those batteries will support electricity systems in Sacramento and in other parts of the country. Therefore, the project has both local and national importance.
Sodium-Ion Battery Plant Sacramento to Produce 4 GWh Annually
The factory will produce enough battery capacity each year to support energy needs on a massive scale. Peak Energy says annual production will equal four gigawatt-hours. According to the company, that amount of storage can provide enough energy annually to power four million homes. That figure highlights the scale of the project and its role in future grid planning.
At the Natomas-area site, Peak Energy will manufacture and store large battery units that measure about 30 feet long. These systems are designed for grid storage rather than consumer electronics. In other words, the plant will focus on utility-scale energy solutions. That focus fits well with growing demand for battery storage as power providers add more renewable energy to the grid.
How the Sodium-Ion Battery Plant Sacramento Supports the Grid
Peak Energy says its sodium-ion batteries will help utilities improve grid resilience, lower system costs, and manage electricity demand more efficiently. For example, battery storage can hold energy when supply is high and release it when demand rises. As a result, utilities can balance the grid more effectively without relying as heavily on new power plant construction.
Dales said the batteries can augment existing capacity and improve the resiliency of the electric grid. He added that this approach can help reduce costs over time. Meanwhile, SMUD has emerged as a key local partner in the effort. The utility believes that adding more renewable energy sources and storage can help drive customer bills down. SMUD board president Dave Tamayo said the region aims to lead the country in reaching zero carbon and showing the electricity industry how to get it done.
Sodium-Ion Battery Plant Sacramento Creates Jobs and Workforce Pathways
The project will also expand job opportunities in Sacramento County. Peak Energy and regional leaders expect the facility to create around 240 jobs. Those positions could offer steady, high-wage work for people entering advanced manufacturing. In addition, local workforce efforts are already helping prepare residents for battery-related roles.
Broome said retraining efforts are underway for workers affected by layoffs in other industries, including former Blue Diamond employees. He emphasized that battery manufacturing can create accessible career paths for people from underserved backgrounds who gain basic technical skills. Consequently, the plant may support both economic mobility and industrial growth.
Sodium-Ion Battery Plant Sacramento Timeline and Partnerships
Peak Energy plans to have the Sacramento site operating by the end of 2027. The company is also building momentum through partnerships. Most notably, Peak Energy recently announced a partnership with General Motors. That agreement adds another layer of visibility to the company’s expansion plans.
With support from SMUD, regional leaders, and industry partners, Peak Energy’s Metro Air Park project could become a defining energy development for Sacramento. The planned factory combines large-scale battery production, job creation, and clean energy goals in one site. As construction moves forward, Sacramento is positioning itself at the center of the next phase of grid storage manufacturing in the United States.
