The Montgomery County Public Schools (MCPS) (Maryland) Board of Education approved a contract on Tuesday evening with Highland Electric Transportation, a provider of turnkey electric fleet solutions, to convert the MCPS school bus fleet to all-electric, starting with 326 school buses over the next four years. This project represents the largest single procurement of electric school buses in North America.

Montgomery County Public Schools operates more than 200 schools and serves more than 160,000 students county-wide. The MCPS Department of Transportation is one of the largest in the country, with an over 1,400 school bus fleet.

Under the agreement, Highland and its project partners, including Thomas Built Buses, Proterra, and Annapolis-based American Bus, will electrify all five of MCPS’ bus depots, supplying the electric school buses and charging infrastructure along with services including managed charging.

Highland will purchase buses manufactured in North Carolina by Thomas Built Buses, which will be supplied and serviced by American Bus. Both companies have been long-time trusted suppliers and partners for the MCPS Department of Transportation.

Designed, engineered, and manufactured in the United States by Thomas Built Buses, the all-electric Saf-T-Liner C2 Jouley school bus is powered by Proterra’s electric vehicle technology platform. The Jouley couples 226 kWh of total energy capacity with a Proterra Powered drivetrain to offer an industry-leading operating range of up to 135 miles on a single charge to meet the needs of school bus fleets.

The transition to electric school buses will deliver health and climate benefits for the community. Converting the school bus fleet will reduce carbon emissions by 25,000 tons per year while cutting diesel pollution harmful to human health, contributing to both Maryland and Montgomery County goals.

The project was awarded an $817,000 grant from Maryland Energy Association (MEA), which helps offset the purchase cost of vehicles that is critical at this early stage of mass deployment. This is the type of project that the MEA Clean Fuels Incentive Program was intended to support, collaboration between the public and private sector to build a scalable fleet electrification market in the state.

In addition, the electric buses will lend their batteries to deliver stored electricity to the local electricity markets, interconnected through Pepco, which helps the community integrate renewable energy and support grid resiliency. Highland takes on the obligation of internalizing these values, which shift the cost of ownership for the electrified fleets, helping to deliver budget neutrality to MCPS.
