Powin is partnering with BHE Renewables as the energy storage solutions provider for a solar and storage microgrid that the companies claim will be one of the world’s largest once completed.

The project, located in Ravenswood, West Virginia, will supply Titanium Metals Corporation with renewable energy to manufacture titanium products for the global aerospace industry.

Powin will deliver a 50 MW battery energy storage system to help power what it’s calling a “first-of-its-kind” renewable energy microgrid alongside a 106 MW solar array. The battery system is engineered to discharge energy continuously for 10 to 12 hours. The partnership also marks one of Powin’s first projects to meet domestic content requirements outlined in the Inflation Reduction Act.

BHE Renewables, a subsidiary of Berkshire Hathaway Energy, will oversee the construction and operation of the solar and battery system, which will be completed in phases aligned with TIMET’s ramp-up to full production. The project is set to commence with initial deliveries beginning in 2025 and reaching full capacity in 2027.

This project marks Powin’s second collaboration with BHE Renewables, including the current development of Solar Star 3 and 4 in Kern County, California. These solar-plus-storage projects demonstrate how renewable energy can drive economic growth, improve grid reliability, and lower our carbon footprint.

Last year, Powin announced it was adding 2 GWh of U.S. production capacity. Powin selected Jabil Inc. as its manufacturing partner to accelerate the development and delivery of the company’s modular battery storage solution, the Stack750.

The company’s battery storage options can be used for grid service and transmission and distribution deferral, as well as behind-the-meter, microgrid, and solar+storage applications. They claim to provide safer and more reliable lithium-ion storage options to customers, boasting over 500,000 hours of incident-free operations.

In 2022, Powin said it raised $135 million in growth equity from GIC, Singapore’s Sovereign Wealth Fund led the investment, with participation from Trilantic Energy Partners North America and Energy Impact Partners. The funding was earmarked to scale its global manufacturing, further develop its suite of products, and support its relationship with international suppliers.
