Eos Energy (EOSE) shares rose 12%, The company previously announced a strategic clean energy partnership with Google and MN8 Energy in West Virginia, USA.

The project integrates 86 MW of solar power generation capacity, as well as a 10 MW/100 MWh Eos proprietary Z3 zinc-based energy storage system and a 70 MW/280 MWh lithium-ion battery.

Google has committed to purchasing the facility's entire energy output, grid capacity and renewable energy certificates.

The total capital expenditure for the joint venture is expected to be US$350 million and is expected to create approximately 200 construction jobs.

This cooperation marks the first time that Google has deployed Eos 'Z3 platform made in the United States, and is also the first project under the main supply agreement between MN8 Energy and Eos.

Eos Energy Corporation (EOSE) shares rose 12% on Wednesday after announcing a strategic partnership with MN8 Energy and Google to develop a joint solar and battery energy storage facility in West Virginia.

The facility will be built on a former coal mine site in Kanova County. MN8 Energy was designated owner and operator and named the project "Mammoth Solar."

The facility is equipped with 86 MW of utility-scale solar panels and integrates two energy storage technologies. Eos will deploy an innovative 10 MW/100 MWh Z3 zinc-based long-term energy storage system complemented by a 70 MW/280 MWh conventional lithium-ion battery system.

The integrated infrastructure is designed to deliver stable, renewable dispatchable power to the PJM interconnected grid on a continuous basis, specifically designed to meet the energy needs of Google's regional data center operations, including a forthcoming West Virginia facility.

Google has agreed to purchase the facility's full power output, grid capacity rights and renewable energy certificates. The move is in line with Google's broader strategy of introducing new clean energy capacity to the grid where it operates Infrastructure services.

Pioneering technology deployment

This project is the first time Google has deployed Z3 battery technology made by Eos in the United States. In addition, it is also the first project under the previously established MN8 Energy and Eos Master Supply Agreement.

The Z3 platform can provide 10 hours of energy storage, allowing solar power to be scheduled in a time period far exceeding that normally supported by traditional lithium-ion configurations. The project is also West Virginia's first commercial-scale long-term energy storage facility.

The solar segment is scheduled to begin commercial operations in 2028. The lithium-ion energy storage component will be put into operation in 2029, while long-term Z3 technology is scheduled to be launched in 2030.

Financial and employment benefits

The project is expected to have a total capital investment of approximately US$350 million. During its first two decades of operation, the facility is expected to contribute approximately $4 million in property tax revenue to benefit Kanova County and local educational institutions.

The construction phase is expected to create approximately 200 jobs and is expected to continue to provide full-time and part-time jobs throughout the facility's operating life.

Eos has located its corporate headquarters and production facilities in Pittsburgh, Pennsylvania, ensuring localized supply chain operations.

The agreement comes as data center operators face growing needs for reliable, environmentally sustainable power supplies. Google has been actively seeking long-term energy storage investments as a cornerstone of a comprehensive energy strategy.

Nathan Kroeker, chief commercial officer of Eos, pointed out that the Z3 platform "extends the value of clean power generation into more hours, strengthens the overall portfolio, and provides more reliable capacity when it is needed most."

Jon Yoder, CEO of MN8 Energy, said the project demonstrates the potential that can be generated when customers like Google are "willing to combine next-generation energy storage technology with utility-scale solar power."

EOSE shares rose 12% on September 2, 2026, just as the partnership was announced.
