Google Tapping A $350 Million Solar Plant Powered With Zinc Batteries
The $350 million project pairs 86 megawatts of solar with lithium-ion and zinc batteries to supply Google’s regional data centers with dispatchable clean power.
- On Wednesday, Eos Energy Enterprises announced a collaboration with Google and MN8 Energy to develop the Mammoth Solar project in Kanawha County, West Virginia, representing up to $350 million in capital investment.
- Struggling with manufacturing delays, Eos Energy secured this agreement as a potential lifeline after burning $422 million in FCF while earning $214 million in sales over the last year.
- The multi-technology asset combines 86 megawatts of solar with dual-storage architecture designed to deliver around-the-clock capacity to the PJM grid, pairing 70 megawatts of lithium-ion batteries with 10 megawatts of Eos' Z3 aqueous zinc long-duration system.
- Commercial operations will roll out in phases starting in 2028, with lithium-ion storage in 2029 and long-duration storage in 2030; Eos Chief Commercial Officer Nathan Kroeker noted the technology converts intermittent solar into a dispatchable resource matching hyperscale data center loads.
- This tripartite partnership provides high-profile hyperscaler validation for Eos' proprietary zinc-based platform, marking Google's first use of American-made Z3 technology and the inaugural project under the MN8-Eos Master Supply Agreement.

Google’s Zinc and Lithium Battery Project Turns West Virginia Coal Mine Into 24/7 Power Source
West Virginia’s old coal country is getting a new purpose. On a 500-acre plot abandoned two decades ago in Kanawha County, solar panels will soon rise alongside batteries that store power for hours or even overnight. Google stands behind the effort. So do MN8 Energy and Eos Energy Enterprises. The $350 million Mammoth Solar project pairs 86 megawatts of utility-scale solar with two types of storage. Short-duration lithium-ion batteries deliver 7…
