Eos Energy Enterprises, Inc, America’s leading innovator in designing, manufacturing, and providing zinc-based long duration energy storage systems sourced and manufactured in the United States, today announced it has signed a memorandum of understanding with Frontier Power Ltd. (“Frontier”), a UK-based energy developer, for a 5 GWh energy storage framework agreement. The agreement marks Eos’ entrance into a new international market and supports Frontier’s plans to submit multiple bids utilizing Eos’ Znyth™ battery technology in the first application window of Ofgem’s new long-duration energy storage (LDES) cap and floor scheme.
“We are proud to partner with Frontier Power, a respected leader in UK energy development, to bring Eos’ safe and recyclable storage technology to a new market,” said Justin Vagnozzi, Senior Vice President of Global Sales at Eos Energy Enterprises. “The novel cap and floor scheme incentivizes investments in long-duration storage technologies that are critical for grid stability and renewable integration. Our participation in this scheme with an established global supply partner like Frontier furthers our commitment to scale our operations, expand our market reach and encourage the adoption of alternative technologies for the energy storage market.”
Under the agreement, Eos and Frontier will also look to expand the collaboration globally to new international markets. This partnership also opens the door to developing local manufacturing in the UK. Should significant LDES project volumes materialize using Eos technology, it could incentivize the establishment of manufacturing operations in the UK, supporting domestic supply chains and job creation.
“Our supply chain strategy was designed to be transportable,” said Joe Mastrangelo, Eos Chief Executive Officer. “We can co-locate manufacturing capacity near customer demand and not only provide innovative energy storage, but sustainable jobs in regions that have demand for our technology. As that demand grows, both domestically and internationally, we’ll expand our manufacturing footprint, and we’re excited to partner with Frontier to execute on that vision in the UK market and beyond.”
“This agreement reflects Frontier Power’s commitment to driving innovation in clean energy while fostering international collaboration,” said Humza Malik, Frontier Power Chief Executive Officer. “By working with Eos, we are advancing our portfolio of long-duration storage projects and strengthening trade relations between the US and UK. The prospect of local manufacturing in the UK could further boost economic growth and job creation.”
The UK’s cap and floor scheme, administered by Ofgem and the Department for Energy Security and Net Zero, is designed to provide long-term revenue certainty for innovative energy storage technologies and help incentivize investment in alternative technologies to lithium-ion in the UK market. Eos’ eight-hour technology is well suited for the program, which supports the UK’s broader goals of achieving grid stability and enables higher levels of renewable integration.
This agreement will be incremental to Eos’ pipeline numbers as of March 31, 2025 when the Company reports first quarter 2025 results.
