ESS Tech, Inc. (NYSE: GWH) (ESS, or the Company), a leading manufacturer of long-duration energy storage (LDES) systems for commercial and utility-scale today applications, today announced a collaboration framework with Salt River Project (SRP) and Google for Project New Horizon<\/a> to advance long-duration energy storage innovation at SRP\u2019s Copper Crossing Energy and Research Center<\/a> in Florence, Arizona.<\/p>\n\n\n\n

Project New Horizon is a five-megawatt (MW), 50 megawatt hour (MWh) system that will deploy ESS\u2019 iron flow Energy Base technology and represents a significant commercial validation milestone for the Company\u2019s next-generation, utility-scale platform. The pilot is expected to support SRP\u2019s evaluation of emerging non-lithium LDES technologies and, if successfully executed, could help unlock follow-on commercial opportunities with utilities and large energy users seeking scalable, LDES solutions.<\/p>\n\n\n\n

ESS\u2019s Energy Base is designed for utility-scale deployments and differs from prior containerized solutions by enabling flexible configuration across diverse use cases and is expected to deliver cost advantages at larger scale.<\/p>\n\n\n\n

The Project New Horizon pilot was awarded through SRP\u2019s competitive solicitation process for LDES technologies. Design is underway, with manufacturing expected to begin in 2026 and delivery targeted for December 2027.<\/p>\n\n\n\n

Under the agreement, SRP intends to partner with Electric Power Research Institute (EPRI) to support project operational testing under an initial, multi-year research scope, with potential for future work. All tests required per the Energy Storage Agreement (ESA) will be performed by SRP and ESS for the duration of the agreement term, with EPRI providing independent oversight.<\/p>\n\n\n\n

Google is a participant in the Copper Crossing project, funding a portion of the project\u2019s payments through a cost sharing arrangement with SRP<\/a>. The collaboration is intended to evaluate real-world operational performance of non-lithium LDES and generate learnings relevant to grid reliability, renewable integration, and broader LDES deployment pathways. SRP and Google have both stated goals to expand clean energy and help make reliable, affordable electricity available around the clock.<\/p>\n\n\n\n

\u201cThis phase of Project New Horizon represents an important commercial validation of Energy Base and a clear signal that utilities are actively pursuing scalable, non-lithium long-duration storage as part of long-term resource planning,\u201d said Drew Buckley, Chief Executive Officer of ESS. \u201cThe collaboration with SRP, along with Google\u2019s participation and cost sharing, reinforces the relevance of long-duration storage for grid reliability and for large energy users focused on carbon-free energy. Successful execution can serve as a blueprint for broader deployments and meaningful follow-on opportunities.\u201d<\/p>\n\n\n\n

\u201cProject New Horizon is part of SRP’s effort to evaluate the impact of long-duration energy storage technologies that could ultimately support SRP’s mission of providing reliable, affordable and sustainable power,\u201d said Chico Hunter, Manager, Innovation and Development at SRP. \u201cWe look forward to working with ESS, Google, and EPRI to assess performance in real-world conditions and advance our understanding of how long-duration storage can serve future system needs.\u201d<\/p>\n\n\n\n

\u201cLong-duration energy storage is needed to improve grid resilience and unlock around-the-clock clean energy,\u201d said Lucia Tian, Head of Advanced Energy Technologies, at Google. \u201cThis collaboration with SRP is intended to accelerate learning and innovation from real-world deployments of a portfolio of emerging long-duration energy storage technologies, including this first pilot with ESS. We\u2019re excited to work with a utility partner who shares our commitment to supporting a range of technologies and diverse supply chains that can bring reliable, affordable, and clean energy to Arizona and across the United States.\u201d<\/p>\n\n\n\n
