Eos Energy and Cerberus Launch $1.5B Insured Storage Platform to Scale US Battery Projects
Event summary
- Eos Energy and Cerberus Capital Management launched Frontier Power USA, a $1.5B insured platform to deploy 2GWh of long-duration zinc-based storage by 2026.
- Cerberus committed $100M in equity, while Eos plans a $150M rights offering to fund its contribution.
- Ariel Green underwrote a 15-year, $1.5B technology performance insurance policy to secure investment-grade project financing.
- Frontier Power USA will operate independently, separating project capital from Eos' corporate balance sheet.
The big picture
This deal marks the first application of capital-intensive deployment platforms—common in aviation and power generation—to long-duration energy storage. By combining Eos' proprietary zinc technology with Cerberus' institutional capital and Ariel Green's insurance framework, the partnership aims to compress project timelines and secure lower-cost financing. The move reflects growing investor confidence in long-duration storage as a grid resilience solution amid electrification and AI demand growth.
