Coulomb Solutions' Mobile Battery Storage Systems Qualify for California CORE Vouchers
Three new models ranging from 233 kWh to 699 kWh approved under CARB's Clean Off-Road Equipment program.
Coulomb Solutions has received California Air Resources Board approval for three mobile battery energy storage systems under the state's Clean Off-Road Equipment voucher program, expanding options for fleet operators seeking zero-emission power solutions.
What Happened
CARB qualified three additional Coulomb Solutions mobile BESS units for its CORE Voucher Program: the 233 kWh eBESS233-233-01 ($93,000 voucher), 466 kWh eBESS466-466-01 ($185,000 voucher) and 699 kWh eBESS699-540-01 ($280,000 voucher). All three systems are 480V AC mobile power units built around lithium iron phosphate cells sourced from CATL. The program offers up to $400 per kWh in incentives. Coulomb Solutions' previously approved 2.3 MWh unit remains eligible for the program's maximum incentive of $300,000.
Why It Matters
The vouchers offset upfront costs for commercially available zero-emission equipment through point-of-sale discounts, making mobile battery storage more accessible to fleet operators at ports, airports, construction sites and industrial warehouses that lack EV charging infrastructure. These systems can enable DC fast charging without utility service upgrades while capping peak demand charges. They also serve temporary power needs at events and replace diesel generators for backup or disaster relief.
The Bottom Line
Coulomb Solutions now has four mobile BESS models approved under California's CORE program, with voucher amounts ranging up to $300,000 per unit depending on capacity.
