Ameresco Collaborates with The Resilience Authority of Annapolis and Anne Arundel County to Advance Fleet Electrification

Ameresco, Inc. (NYSE: AMRC), a leading energy solutions provider dedicated to helping customers navigate the energy transition, today announced the execution of a design-build contract with The Resilience Authority of Annapolis and Anne Arundel County, Maryland to deploy electric-vehicle (EV) charging infrastructure across 10 County-owned facilities.

Selected through a competitive bid process, Ameresco conducted a comprehensive strategic analysis of the County’s existing fleet, fueling data, and electric vehicle procurement plans, including charging simulations to determine optimal right-sized solutions. This collaboration supports the County’s transition to an electrified fleet and reflects a shared commitment to sustainability, operational efficiency, and innovation in public sector fleet management.

The recommended managed charging approach is projected to deliver approximately $350,000 in annual utility savings once the fleet is electrified. The study also identified opportunities to reduce the electrical capacity required to maintain fleet operations by approximately 2.5 megawatts across the 10 facilities, resulting in capital savings and greater flexibility for future growth.

“Our goal from the start was to identify a smart, scalable path to fleet electrification that balances cost, reliability, and long-term flexibility,” said Susan Herrold, Anne Arundel County Central Services Officer. “By partnering with the Resilience Authority and Ameresco, we’ve been able to turn thoughtful planning into measurable action. Together, we’re reducing emissions, improving operational efficiency, and investing in modern infrastructure that can evolve as the County’s needs grow.”

A phased deployment plan helps ensures scalable and flexible infrastructure, with initial installations sized for planned vehicle procurement through 2026. This approach also helps ensure each site installs the optimal number of chargers for near-term needs while future-proofing additional spaces and capacity to support seamless fleet expansion.

“We’re proud to partner with The Resilience Authority and Anne Arundel County to turn thoughtful analysis into practical, scalable infrastructure,” said Peter Christakis, President of East USA & Greece; Project Risk at Ameresco. “By right-sizing charger counts, optimizing electrical capacity, and sequencing deployment, we’re helping the County accelerate fleet electrification while controlling costs and strengthening day-to-day operations.”
