Peak Energy, a U.S.-based company focused on developing low-cost, large-scale energy storage solutions for the electrical grid, has entered into a multi-year, phased supply agreement with Jupiter Power LLC, a prominent operator of utility-scale battery energy storage systems. Under the terms of the contract, Peak Energy will deliver up to 4.75 GWh of its sodium-ion battery energy storage systems for deployment between 2027 and 2030.
Peak Energy’s sodium-ion technology offers several advantages over conventional lithium-ion systems, including reduced degradation over the battery’s operational lifetime and lower operations and maintenance costs. The cells are designed for minimal performance loss, which can decrease the need for capacity augmentation over time. The storage systems also incorporate a fully passive cooling architecture, eliminating active thermal management components that require routine servicing and lowering auxiliary power requirements by up to 97 percent.
“From day one, we have believed that sodium-ion will be the winning technology for grid-scale storage, which is absolutely essential to meet increasing demand from hyperscalers and AI. Deploying the world’s largest sodium-ion energy storage system with one of the nation’s top Independent Power Producers proves that sodium is ready for today and will dominate the future,” said Landon Mossburg, CEO and Co-Founder at Peak Energy. “Jupiter Power has always been on the cutting edge of technology adoption and development, and their team deeply understands the need to invest in and deploy technology solutions that will deliver long- term financial and operational savings to customers. We are thrilled to partner with them to bring Peak Energy’s technology to the market.”
“Jupiter Power is excited to support domestic battery energy storage manufacturing as we continue to increase the deployment of firm, dispatchable energy when and where it’s most needed,” said Mike Geier, Jupiter’s Chief Technology Officer. “Peak Energy’s approach to battery innovation is a potential game changer for the industry and we applaud them as a first mover in domestic sodium-ion technology.”
Under the initial phase of the agreement, Peak Energy will supply approximately 720 MWh of storage capacity in 2027—marking the largest single deployment of sodium-ion batteries to date. The contract also includes an option to deliver an additional 4 GWh of capacity from 2028 through 2030. At full scale, the agreement could be valued at more than $500 million, underscoring the industry’s momentum behind sodium-ion solutions.
This supply deal follows Peak Energy’s recent launch of its proprietary NFPP grid-scale sodium-ion system, which delivers nearly 30 percent better cell degradation performance over 20 years compared to current market offerings. The company continues to advance its goal of establishing a domestic sodium-ion supply chain and driving down the total cost of ownership for utility-scale energy storage applications.
