The buses represent the largest fleet of Proterra all-electric buses in the nation. Gov. Patrick also announced a new initiative, the Massachusetts Offers Rebates for Electric Vehicles program, which will provide rebates of up to $2,500 for plug-in hybrid and electric vehicles. All residents of the Commonwealth are eligible to receive incentives on vehicles registered in Massachusetts; these incentives will be funded with $2 million in Regional Greenhouse Gas Initiative auction proceeds. Governor Patrick also awarded nearly $600,000 in Massachusetts Electric Vehicle Incentive Program (MassEVIP) grants to 16 municipalities, two public universities and colleges and one state agency for the acquisition of plug-in hybrid or battery-electric vehicles and the installation of Level 2 charging stations. This is the second round of grant awards through MassEVIP since its launch last year.
