A $2 million pilot project, funded through the Regional Greenhouse Gas Initiative, allowed three school districts to purchase Type C electric school buses and Level 2 bidirectional vehicle-to-grid (V2G) charging stations to test the technology in cold weather environments in Massachusetts.

Combined, the three buses traveled approximately 14,000 miles and provided transportation for 279 days. Though the pilot has ended, the school districts still operate the electric buses and DOER (Department of Energy Resources) continues to evaluate their impact. During the pilot, the life cycle greenhouse gas (GHG) emissions were about half of what emissions from diesel buses would have been.
