Electric energy savings from new technologies
This report was prepared by Pacific Northwest Laboratory for the Office of Coal and Electricity Pol icy (OCEP), U.S. Department of Energy. The purpose of the report is to provide information about the electricity-saving potential of new technologies to OCEP that it can use in developing alternative long-term projections of u.s. electricity consumption. low-, base-, and high-case scenarios of the electricity savings for ten technologies were prepared. The total projected annual savings for the
... ar 2000 for all ten technologies were 137 billion kilowatt hours (BkWh), 279 BkWh, and 470 BkWh, respectively, for the three cases. The magnitude of these savings projections can be gauged by comparing them to the Department•s reference case projection for the 1985 National Energy Po 1 icy Plan. In the [)epartment • s reference case, tot a 1 consul'lpt ion in 2000 is projected to be 3319 AkWh. Thus, the savings projected here represent between 4 percent and 14 percent of total consumption projected for 2000. Because approximately 75 percent of the base-case estimate of savings are already incorporated into the reference forecast, reducing projected electricity consumption from what it otherwise would have been, the savings estimated here should not be directly subtracted from the reference forecast. ;;; EXECUTIVE SUMMARY This report was prepared by Pacific Northwest Laboratory (PNL) for the Office of Coal and Electricity Policy (OCEP), U.S. Department of Energy. The purpose of the study was to provide information about new electricity-saving technologies to the OCEP that it can use in the development of alternative forecasts of U.S. electricity consumption for the fifth National Energy Policy Plan (NEPP). The project had three specific objectives. The first objective was to collect information about the technical characteristics and costs of ten important new electricity-saving technologies. The second objective was to estimate base, low, and high scenarios of the future potential market, market penetration rate, and impact on aggregate u.s. electricity consumption of each of the ten technologies. These projections were intended to be first-cut or approximate estimates of the potential magnitude of the impacts of these technologies. The third objective was to generate approximate estimates of the average levelized cost per kilowatt hour saved by each technology. These estimates were to be compared to published estimates of the cost of new generating capacity to determine if utility efforts to facilitate penetration of any of the technologies might be a cost-effective alternative to construction of new generating capacity.
