Eos Energy Stock Jumps 12% on Google, MN8 Energy Storage Deal for West Virginia Solar Project
Shares of Eos Energy Enterprises (NASDAQ:EOSE) surged 12% on Wednesday following the announcement of a key partnership with MN8 Energy and Google for a large-scale solar and energy storage project in West Virginia. The project will supply clean, dispatchable power to the PJM grid for Google's regional data centers.
Project Details
The Mammoth Solar project, to be located in Kanawha County on a reclaimed coal mine, integrates multiple technologies to ensure a reliable power supply. MN8 Energy will own and operate the facility, which combines utility-scale solar with two types of battery storage.
The project's key components include:
- 86 MW of utility-scale solar generation.
- 10 MW/100 MWh of Eos's Z3 zinc-based long-duration energy storage.
- 70 MW/280 MWh of traditional lithium-ion energy storage.
Eos's system is designed to provide 10 hours of energy storage, significantly extending the availability of solar power beyond the capabilities of shorter-duration resources. According to the announcement, Google will purchase the energy, capacity, and clean energy attributes generated by the integrated portfolio.
AdStrategic Significance
This collaboration marks Google's first deployment of Eos's American-made Z3 zinc battery technology. It is also the inaugural project under a previously announced Master Supply Agreement between Eos and renewable energy firm MN8 Energy.
For investors, the deal represents a significant validation of Eos's long-duration storage technology by a major corporate energy buyer. The project's phased timeline targets the solar facility to begin commercial operation in 2028, with the lithium-ion and Eos storage systems following in 2029 and 2030, respectively.
Economic Impact
The project represents a substantial capital investment of up to $350 million in West Virginia. It is expected to create approximately 200 construction jobs and generate an estimated $4 million in property tax revenue for the county and local schools over its first 20 years of operation.
