Battery startup Viridi takes over Moxion’s California factory

Strengthening California’s Grid Resilience with Next-Generation Fail-Safe Battery Energy Storage

RICHMOND, Calif., April 21, 2025 – When the startup Moxion went under last year, some in the industry lamented the company’s overconfidence. Moxion sold a portable battery, with 75 kilowatts of power and over 600 kilowatt-hours of energy, meant to replace diesel generators for live events, disaster response, construction, and defense applications. The idea gained traction, enabling the company to raise a $100-million Series B in 2022. But it also encouraged too much growth, too fast.

That’s where Viridi, a battery energy storage company based in Buffalo, New York, is looking to step in.
