With demand for zero-emission transportation incentives near an all-time high (more than $100 million in Standard HVIP vouchers were oversubscribed in the first 36 hours), the recent deadline extensions for several key Southern California funding programs provide applicants with valuable additional time to assemble competitive proposals.
South Coast Air Quality Management District’s (South Coast AQMD) INVEST CLEAN programs, totaling more than $467 million in grant funding, have received an extension, giving commercial fleets, charging infrastructure developers, and clean tech stakeholders additional time to finalize applications by the new deadline. Measures 1, 2.1, and 3 have all been pushed out by two weeks, from November 28 to December 16, 2025, by 12pm PT. The five programs (Table 1 below) aim to support battery-electric on-road vehicles, off-road equipment, charging infrastructure, and locomotives. Measure 4, which targets locomotives in the SoCal region, was originally due in September but also received an extension earlier this fall to December 16.
Measure 2.2, the Last Mile Freight Program Battery-Electric Vehicle (BEV) Rebates, recently opened and is accepting applications for Class 4 and 5 BEVs through January 30, 2026. This sub program is being administered by the Southern California Association of Governments and will fund scrap-and-replace or conversion projects for Class 4 and 5 BEVs at up to $67,000 per vehicle.
The INVEST CLEAN programs are funded by South Coast AQMD’s EPA Climate Pollution Reduction Grant award and aim to modernize the Southern California goods movement and logistics corridors by transitioning to battery-electric technologies. The programs cover the region from the San Pedro Bay Ports through Los Angeles, Orange, San Bernardino and Riverside Counties, extending to the California, Arizona, and Nevada borders. While the programs could return in 2026 if the full allocation is not awarded, the funding originates from a one-time U.S. EPA allocation. These robust funding opportunities should be treated as a high priority – eligible applicants won’t want to miss out on tens of thousands to millions in funding.
