Mission-focused Federal Government infrastructure optimization and resiliency solutions

At Ameresco, our people – their expertise, dedication, and commitment to partnership and innovation – are our greatest strength. Given the unique requirements and culture within the Federal sector, we maintain a Federal Group as a direct report to the Chief Executive Officer, alongside regional groups that support non-Federal customers nationwide. This stability within Ameresco Federal Solutions has enabled us to build standing teams of engineers, construction managers, operations & maintenance (O&M) personnel, and measurement & verification (M&V) specialists.

Performance Contracting

Ameresco has guaranteed more than $2.8 billion in savings on energy savings performance contract (ESPC) and utility energy service contract (UESC) projects nationwide for agencies across the federal government. According to Department of Energy (DOE) data on federal ESPC awards, Ameresco has guaranteed more savings per dollar invested than any other ESCO in the history of the ESPC program.

Ameresco has analyzed, recommended, and installed energy conservation measures in all 20 DOE technology categories ranging in scope from a few select buildings to installation-wide energy conservation measures (ECMs), with dollar values ranging from $1 M to $195 M, and with financing terms ranging from 7 years to 23 years.

We perform on-site O&M services, including repair and replacement, as well as measurement and verification activities, as part of ESPCs and UESCs in the performance period at dozens of federal sites and military installations nationwide.

With respect to resiliency, Ameresco is currently designing or deploying fence-to-fence, Unified Facilities Criteria (UFC)-compliant projects for each military service, featuring on-site power generation, energy storage, and microgrid controls solutions that enhance resiliency and reliability while generating energy savings.
