The U.S. Department of Energy’s (DOE) Oak Ridge National Laboratory performs annual assessments of the realization rate of energy and cost savings from DOE’s energy savings performance contract (ESPC) program and publishes the findings in annual performance reports. These documents are based on the information reported by energy service companies carrying out ESPC projects at federal sites.
For FY2019, the DOE IDIQ ESPC program found the following results:
- Projects reported achieving 109.5% of the guaranteed cost savings
- ESPC contractors guaranteed 91.4% of the estimated cost savings
- Projects reported achieving 100.1% of the estimated cost savings.
