Frontier Power USA Formed to Accelerate Deployment of American-Made Long-Duration Energy Storage Infrastructure
Frontier Power USA ("Frontier" or the "Company"), a newly established long-duration energy storage development and investment platform, today announced its formation to accelerate the deployment of critical, utility-scale storage infrastructure across the United States
Frontier has received a $100 million direct equity commitment from Cerberus Capital Management L.P. ("Cerberus") and is expecting to receive an approximately $150 million equity investment from Eos Energy Enterprises (NASDAQ:EOSE), ("Eos") funded via a pro rata rights offering, allowing participating Eos shareholders to maintain proportional ownership in Eos' participation in Frontier Power USA
Frontier is expected to be a purpose-built independent development and investment company utilizing Eos' vertically integrated technology stack to accelerate gigawatt-scale deployment of American-made energy storage technology
Frontier has secured a ~$1.5 billion, project-based, 15 year-non cancellable technology performance insurance ("TPI") policy framework arranged with Ariel Green to accelerate multi-year project bankability
Frontier has entered into a 2 GWh take-or-pay Capacity Reservation Agreement with Eos, securing dedicated manufacturing capacity for the Company to meet significant demand expected from its current and future pipeline
NEW YORK, May 13, 2026 (GLOBE NEWSWIRE) -- Cerberus Capital Management, L.P. ("Cerberus"), one of the country's largest alternative investment firms, along with Eos Energy Enterprises, Inc., a leading U.S. manufacturer of American-made, zinc-based Z3 long-duration energy storage infrastructure, today announced the intention to form Frontier Power USA, an independent development and investment company established to develop, own, and operate a diversified portfolio of long-duration battery energy storage systems structured to deploy at scale with institutional capital and long-term ownership. Frontier Power USA was formed to solve the execution gap that has historically constrained long-duration storage — where proven technology, manufacturing capacity, and customer demand exist, but deployment is slowed by fragmented ownership, financing complexity, and misaligned incentives
Frontier Power USA is intended to address rapidly rising electricity demand and grid reliability challenges driven by the growth of AI-driven data centers and advanced computing infrastructure, while also supporting broader energy security objectives and the integration of renewable generation. The Company is expected to unify three core capabilities that have historically sat across multiple stakeholders: Eos' vertically integrated technology stack, Cerberus's institutional capital and operating experience, and a performance wrap to be provided by Ariel Green, which underwrites Z3 performance. The performance wrap underpins the structure and will allow project debt to achieve investment-grade characteristics at competitive terms. By aligning manufacturing access, development capital, insurance-backed performance, and project financing under a single platform, Frontier is designed to compress timeframes from commitment to commercial operation relative to traditional project-by-project development model
Manufacturers in capital-intensive industries, from aviation to power generation, have long invested into or partnered with development execution vehicles to accelerate customer deployment, and those platforms have generated significant value for stakeholders over time. Frontier USA is targeting to be the first application of that proven playbook to long-duration energy storage.
Accelerated Project Deployment
In connection with the expected launch, Eos and Frontier Power USA entered into a 2 GWh Capacity Reservation Agreement, with the American-Made, Eos Z3 batteries purchased through this agreement expected to be deployed across AI data centers, commercial and industrial applications, and utility-scale projects, drawing from Frontier Power USA's project acquisition pipeline. Approximately 5 GWh of the acquisition pipeline is under active development with a further 20 GWh of identified pipeline providing significant potential future growth opportunities. Dedicated manufacturing access is intended to provide a higher degree of delivery certainty for Frontier Power USA and supply chain security compared to merchant or opportunistic procurement strategies.
Firm Technology Performance Insurance (TPI) with Ariel Green
Technology Performance Insurance serves as a core enabler of Frontier Power USA's model, addressing one of the most persistent barriers to scaling non-lithium long-duration storage: lender confidence over multi-decade asset lives. Simplifying project bankability and accelerating asset deployment, Frontier Power USA has secured a firm Technology Performance Insurance (TPI) framework with Ariel Green, a division of Ariel Re and a leader in clean energy insurance. The framework contemplates a 15-year non-cancellable coverage, which will be sized at the project level with a multi-year total policy capacity of up to approximately $1.5 billion, written through a Lloyd's of London consortium (A+/AA-).
Anchored by Institutional Capital, Extensive Operating Experience, and Investment Grade Cash Flow Profile
Cerberus is anchoring Frontier Power USA with a $100 million direct equity commitment, motivated by its strategic institutional prioritization of sectors which promote technology leadership, resource sufficiency, and supply chain resilience for the United States and its allied partners. Cerberus will receive Eos warrants, as well as controlling equity in Frontier Power USA in exchange for its commitment. Along with the expected equity contribution from Eos, Frontier Power USA can act immediately on a significant near term pipeline of critical long-duration energy storage developments.
Supported by the equity investments, experienced management team, the TPI insurance policy, and investment grade offtakers such as utilities, energy traders, and hyperscalers, Frontier is pursuing investment grade financing provided by institutional-backed captive insurance platforms, commercial banks, and dedicated infrastructure funds, optimized by the offtake profile of the long-duration storage infrastructure assets and regional power market dynamics.
Eos Rights Offering
To fund its equity contribution in Frontier Power USA, Eos intends to launch a rights offering targeting approximately $150 million. In this rights offering, existing Eos common shareholders, including retail investors, would receive a distribution of subscription rights to purchase Eos securities and corresponding warrants. The rights offering is expected to be structured to limit dilution to participating Eos shareholders and allow them to participate pro rata in the Eos investment into Frontier Power USA.
Strategic Rationale
Frontier Power USA is expected to represent a first-of-its-kind long-duration storage platform: a vertically integrated BESS developer and planned IPP with direct OEM access from cell through software. The newly-formed company will have direct access to an OEM at the cell IP level, through module and system architecture to the proprietary software layer, creating end to end integration that reduces the risks in third party assembled supply chains. It's a purpose-built independent developer and IPP working in direct partnership with Eos funded by institutional equity and market-leading debt financing providers. Frontier is expected to be a growth engine, with cash flow generated by operating projects systematically reinvested into the platform, funding new project origination, accelerating Eos equipment deployment, and compounding the value of the integrated technology stack.
Management Commentary
"We expect that Frontier Power USA will bring the speed and ability to scale that the grid urgently needs, at a time when the opportunity set is being driven by energy security requirements and sustained growth in power demand from electrification and AI. By pairing the company's execution and deployment platform with Eos' differentiated long-duration storage technology and expanding U.S. manufacturing base, we believe this model creates a credible path to delivering storage capacity at scale. The platform is designed to translate proven technology into reliable, deployable assets that can keep pace with the system's evolving needs."
— Aaron Maczonis, Managing Director at Cerberus Capital Management.
"As energy storage projects scale, bridging the gap between technology innovation and associated liabilities becomes essential. This transaction through Frontier Power USA shows how TPI can play that role, supporting both bankability and repeatable platform growth across the U.S."
— Jamie Daggett, Energy Storage Practice Lead, Ariel Green
"Frontier Power USA is designed to change the speed of long-duration storage financing and deployment, allowing customers to have faster access to capital and deep expertise in project development. We feel confident that this will give Eos a new growth trajectory as we continue to expand manufacturing capacity. The platform pairs our integrated technology stack with institutional capital and a lender-ready performance framework that is designed to deliver what matters most: electrons to the grid. We believe the planned structure maintains shareholder alignment by allowing Eos investors to participate pro rata in Frontier's Power USA's growth via Eos' ownership while ensuring project capital is governed independently and on arm's-length commercial terms."
— Joe Mastrangelo, Chief Executive Officer Eos Energy
