Pennsylvania's Department of Environmental Protection has extended its Alternative Fuel Vehicle Rebate program, which will continue to provide $2,000 rebates for 500 additional large-battery system plug-in hybrid electric and battery-electric vehicles, or until Dec. 31.

The largest rebates are available for vehicles whose battery system capacities are greater than 10 kilowatt hours, including the Nissan Leaf, Ford Focus, BMW, Tesla and Chevy Volt.

The state is also extended $1,000 rebates for plug-in hybrid electric vehicles and battery-electric vehicles with battery system capacities of less than 10 kWh, including models such as the Toyota Prius plug-in, Ford C-Max Energi, Ford Fusion and Honda Accord.

“The Corbett administration remains committed to seeing the alternative fuels market grow,” DEP Secretary E. Christopher Abruzzo said. “Our commitment represents an impressive total investment of $4.35 million towards the deployment of electric vehicles in Pennsylvania since 2011.”

Pennsylvania also offers rebates of $1,000 for natural gas, propane, hydrogen or fuel-cell vehicles, such as the CNG powered Honda Civic or any 2014 CNG powered car or pickup truck, with CNG original equipment, manufacturer retrofits or certified conversions to CNG or propane also eligible for the rebate. A $500 rebate is available for electric motorcycles and scooters.
