Dominion Energy Unveils Mobile Battery System as Clean Alternative to Diesel Generators
Dominion Energy announced the deployment of a first-of-its-kind mobile battery energy storage system designed to replace diesel generators with a clean, quiet, and emissions-free power source. The company marked the launch with a ribbon-cutting event in Richmond, Virginia.
The Green Grid 90 kWh mobile battery energy storage system generates electricity from rooftop solar panels and stores it in a lithium-ion battery, while also allowing charging from the grid. The trailer-mounted units are silent, fuel-free, towable by a mid-sized SUV, and can be linked together to meet higher power demands. They are intended for use at festivals, concerts, weddings, remote worksites, electric vehicle charging, and as backup power during outages for utilities and emergency management agencies.
Dominion Energy said the system is the first non-diesel mobile battery solution to meet stringent safety standards, including UL 9540 certification, enabling it to be insured. A single unit can power a medium-sized food truck for up to nine hours. Prototype units were previously used to support emergency communications during Florida’s recovery efforts following Hurricanes Helene and Milton in 2024.
The system was invented by Dominion Energy and is designed, manufactured, sold, and serviced by Power Up Connect, a Maryland-based charging technology company. Dominion Energy Virginia plans to position multiple units at its facilities, starting with its Chesterfield training center.
