With 147 million Americans in 43 states breathing unhealthy air, the cleanest kilowatt is the kilowatt saved. At the American Council for an Energy-Efficient Economy (ACEEE) Summer Study, Christopher James spoke about the efficiency power plant model (EPP) as an air quality strategy. An EPP is a carefully selected set of demand-side management and energy efficiency programs designed to reduce demand and meet specific load curve needs in the aggregate, whether base or peak load. As a result, EPPs allow energy efficiency to be integrated into power sector planning and financing in the same way as supply-side resources. Advocates can use the EPP model to illustrate the MWh “output” of efficiency programs and correlate the savings to emissions reductions.Mr. James encouraged energy efficiency advocates to engage not only with state air regulators, but also with the headquarters and regional offices of the United States Environmental Protection Agency (EPA) to ensure the inclusion of energy efficiency in compliance plans. This is particularly important as states develop their plans to comply with the EPA’s Clean Power Plan.
