Frontier Power USA Launches to Tackle America's Energy Storage Challenge

NEW YORK, NY – May 13, 2026 – A new venture, Frontier Power USA, launched today with over a quarter-billion dollars in initial backing, aiming to solve a critical bottleneck in America's transition to clean energy: the deployment of long-duration energy storage (LDES). Backed by a $100 million commitment from investment giant Cerberus Capital Management and an expected $150 million from U.S. battery manufacturer Eos Energy Enterprises, Frontier is designed to fast-track the construction of utility-scale storage projects essential for grid stability and powering the nation's growing digital economy.

The company's formation represents a novel, vertically integrated approach to a problem that has long stymied the energy sector. By combining institutional capital, dedicated access to American-made battery technology, and a groundbreaking insurance framework, Frontier aims to bridge the "execution gap" that has kept gigawatt-scale LDES projects from reaching widespread deployment.

A New Blueprint for Green Infrastructure

For years, the promise of long-duration energy storage—systems that can dispatch power for 10 hours or more—has been hampered by a fragmented and complex development landscape. Projects have faced a trifecta of challenges: high upfront capital costs that deter traditional lenders, perceived performance risks associated with newer technologies, and complex market structures that fail to properly value their grid-stabilizing benefits. Frontier Power USA was purpose-built to dismantle these barriers.

The platform unifies three core components that have historically operated in separate silos. First, Cerberus provides the institutional capital and operational experience needed to fund large-scale infrastructure. Second, a strategic partnership with Eos secures a direct supply of its Z3 zinc-based batteries, mitigating supply chain risks and ensuring access to a proven, non-lithium technology manufactured in the United States.

The third and perhaps most innovative component is a ~$1.5 billion, 15-year non-cancellable Technology Performance Insurance (TPI) policy arranged with Ariel Green. This insurance effectively underwrites the battery system's long-term performance, providing the certainty lenders need to offer investment-grade financing.

"We expect that Frontier Power USA will bring the speed and ability to scale that the grid urgently needs," said Aaron Maczonis, Managing Director at Cerberus Capital Management. He noted that the platform is designed to "translate proven technology into reliable, deployable assets that can keep pace with the system’s evolving needs."

This integrated model aims to compress project timelines dramatically, moving from development to commercial operation far faster than the traditional, piecemeal project-by-project approach.

Powering the AI Boom and Securing the Grid

The urgency for LDES is being amplified by an unprecedented surge in electricity demand, driven largely by the explosive growth of artificial intelligence and data centers. These facilities require massive amounts of reliable, 24/7 power, a demand that is straining grids across the country and challenging decarbonization goals.

While short-duration lithium-ion batteries are effective for a few hours of storage, they are often economically and technically unsuited for providing the continuous power needed to back up intermittent renewables like solar and wind for extended periods. This is where LDES becomes critical. By storing excess renewable energy for 10 hours or more, systems like those Frontier will deploy can provide firm, clean power around the clock, ensuring data centers meet both their uptime requirements and their sustainability targets.

Frontier is entering the market with a significant pipeline, including a 2 GWh take-or-pay capacity reservation agreement with Eos. The company has approximately 5 GWh of projects already under active development, with a further 20 GWh identified, targeting AI data centers, commercial and industrial clients, and utility-scale grid support.

"Frontier Power USA is designed to change the speed of long-duration storage financing and deployment," commented Joe Mastrangelo, CEO of Eos Energy. "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."

The Insurance Linchpin: De-Risking New Technology

A key obstacle for non-lithium battery technologies has been convincing conservative project financiers of their long-term reliability. Without years of widespread operational data, lenders often apply a risk premium that can make projects economically unviable.

Frontier’s partnership with Ariel Green, a division of premier reinsurance underwriter Ariel Re, directly confronts this challenge. The 15-year, non-cancellable TPI policy is a financial backstop that guarantees the performance of Eos’s Z3 batteries. If the systems fail to meet specified metrics for capacity or efficiency, the insurance policy covers the financial shortfall. This shifts the technology performance risk from the project investors to the insurer, a move that is expected to unlock more favorable, investment-grade debt financing.

"As energy storage projects scale, bridging the gap between technology innovation and associated liabilities becomes essential," explained Jamie Daggett, Energy Storage Practice Lead, Ariel Green. "This transaction through Frontier Power USA shows how TPI can play that role, supporting both bankability and repeatable platform growth across the U.S."

This insurance framework is seen as a critical enabler, not just for Frontier, but potentially as a model for the broader clean technology sector, helping other innovative but not-yet-mainstream technologies cross the "valley of death" to commercial scale. By creating a bankable structure around a domestically produced technology, the platform aligns with broader national goals of enhancing energy security and rebuilding America's industrial base.

The combination of dedicated manufacturing, institutional capital, and robust insurance creates a powerful engine for deployment, positioning Frontier to become a significant independent power producer (IPP) in the rapidly expanding energy storage market. Its success could pave the way for a new era of green infrastructure development, one defined by integration, speed, and scale.
