Through our partnership with energy solutions provider Ameresco, our ChargePilot® charging and energy management system is being implemented at county facilities throughout the Annapolis and Anne Arundel County region. With its automated load management capabilities, ChargePilot allows the county to optimize charging schedules by shifting to off-peak periods and minimizing peak demand. This strategy ensures that every vehicle is fully charged and ready for daily operations while achieving significant cost savings compared to traditional unmanaged charging methods.
Comprehensive Analysis
Ameresco conducted a comprehensive fleet assessment, analyzing daily duty cycles and vehicle specifications for each facility. Together, we leveraged this data to run detailed charging simulations, enabling us to determine the precise electrical capacity required in a managed charging environment. By aligning the infrastructure to the fleet’s actual operational needs, rather than the nameplate capacity of the chargers, we’ve been able to significantly reduce the electrical capacity needed for charger installations.
Phased Deployment
The infrastructure is designed to accommodate the county's planned vehicle procurement through 2026, with future-proofing in place to enable seamless expansion. In total, 82 charging ports will be installed across nine county-owned facilities. Additionally, one of these facilities will be equipped with make-ready infrastructure, allowing for easy charger installation in the future.
Mixed Fleet
The project involves the installation of Level 2 and DC fast chargers to primarily support light-duty vehicles from various government departments, such as the Health Department and the Inspections & Permits, Zoning Review Department. Additionally, these chargers will be accessible to medium-duty vehicles at select locations.
Projected Savings
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 all facilities, resulting in capital savings and greater flexibility for future growth.
"We’re proud to partner with The Resilience Authority and Anne Arundel County to turn thoughtful analysis into practical, scalable infrastructure. 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."
