With utility providers as our customer, Ameresco drives improvements in the reliability, efficiency, and performance of Federal buildings and facilities.

Ameresco is a pre-qualified Utility Energy Service subcontractor partner with multiple utility companies, including Pacific Gas & Electric Company, Duke Energy, Oklahoma Gas & Electric, Eversource, CenterPoint Energy Resources, and AGL Services.

Ameresco supports utility customers with a suite of tools, templates, and best practices drawn from years of UESC experience and lessons learned.  For example, we complete 65% project design during the IGA phase to solicit realistic vendor pricing in response to detailed bid packages, which reduces project risk.

Through a Utility Energy Service Contract (UESC), Ameresco works with utilities to help Federal customers:

  • Reduce energy consumption
  • Reduce operating expenses
  • Upgrade and maintain facilities
  • Stabilize energy costs
  • Improve occupancy comfort levels
  • Increase energy reliability
  • Enhance the environment
