Constellation Energy's Projects & Services Group has been awarded an indefinite delivery indefinite quantity energy savings performance contract by the US Department of Energy.

According to the company, the contract enables Constellation Energy’s Projects & Services Group to continue to conduct energy efficiency, renewable energy and water conservation projects at federally owned buildings and facilities.

The new US Department of Energy’s (DOE) energy savings performance contract (ESPC) enables all federal sites worldwide to utilize the energy services expertise of Constellation Energy’s Projects & Services Group.

Constellation Energy said that, the award replaces several regional and technology specific contracts already held by its Projects & Services Group to provide ESPC services in the Midwest and mid-Atlantic regions; and biomass, alternative methane fuels and geothermal heat pump technologies to federal sites.

The DOE estimates that the ESPC with all contractors could result in up to $80 billion in energy efficiency, renewable energy and water conservation projects. The term of the DOE ESPC contract is five years with two optional three-year extensions.

ESPCs enable federal agencies to undertake energy savings projects without paying up-front capital costs. Under an ESPC, Constellation Energy’s Projects & Services Group designs, constructs and obtains the necessary financing for an energy savings project, and the federal agency makes payments over time from the energy cost reductions.
