【 摘 要 】

The objective of this work was to determine the realization rate of energy and cost savings from the Department of Energy's Savings Performance Contract (ESPC) program based on information reported by the energy services companies (ESCOs) that are carrying out ESPC projects at federal sites. Information was extracted from 134 Measurement and Verification (M&V) reports to determine reported, estimated, and guaranteed cost savings and reported and estimated energy savings for the previous contract year. Because the quality of the reports varied, it was not possible to determine all of these parameters for each project. For 133 of the 134 projects, there was sufficient information to compare estimated, reported, and guaranteed cost savings. For this group, the total estimated cost savings for the reporting periods addressed were $95.7 million, total reported cost savings were $96.8 million, and total guaranteed cost savings were $92.1 million. This means that on average: ESPC contractors guaranteed 96% of the estimated cost savings, projects reported achieving 101% of the estimated cost savings, and projects reported achieving 105% of the guaranteed cost savings. For 129 of the projects examined, there was sufficient information to compare estimated and reported energy savings. On the basis of site energy, estimated savings for those projects for the previous year totaled 5.371 million MMBtu, and reported savings were 5.374 million MMBtu, just over 100% of the estimated energy savings. On the basis of source energy, total estimated energy savings for the 129 projects were 10.400 million MMBtu, and reported saving were 10.405 million MMBtu, again, just over 100.0% of the estimated energy savings.
