Dominant Energy Virginia has filed a proposal with the Virginia State Corporation Commission for a battery storage pilot project that will test two new technologies as alternatives to lithium-ion batteries. The proposed storage project is expected to begin in late 2024 and cost approximately $70.6 million. It will include a roughly 5 MW/500 MWh system from Form Energy, and a 4 MW/16 MWh battery from Eos Energy. According to Dominion, the offshore wind project could save customers in Virginia more than $3 billion in the first decade of its operation, with the potential to go up to $6 billion depending on commodity market pressure trends. Form Energy’s iron-air technology can store electricity for 100 hours, at system costs that the company says is competitive with legacy power plants. Eos’ zinc-powered storage technology, meanwhile, can provide between 3 and 12 hours of storage. If the deal comes through, the company expects to hit a 8 GWh annual production capacity by 2026.
