Connecticut is sweetening state incentives for consumers who purchase electric vehicles. Gov. Ned Lamont’s office announced Monday that rebates under the state’s Connecticut Hydrogen and Electric Automobile Purchase Rebate (CHEAPR) program will increase to between $750 and $7,500, depending on the type of vehicle purchased. That’s up from between $500 and $5,000. The state is also extending the program to the purchase of used electric vehicles. Connecticut currently has about 7,000 electric vehicles on its roads, the administration said. The administration estimates that state consumers need to be driving 125,000 to 150,000 electric vehicles by 2025 and 500,000 by 2030 to meet the state’s statutorily mandated greenhouse gas reduction target.
