Performance based State Efficiency Program (PSEP)

Exploring Strategies for Implementing a Performance based State Efficiency Program: State Energy Consumption Metrics

In order to meet the goal of abating global warming at least cost, a U.S. federal climate and energy policy must invest in unlocking America’s energy efficiency potential. One approach to reliably measuring energy efficiency performance at the state level is to implement a Performance based State Efficiency Program (PSEP). PSEP addresses the question of whether energy intensity is improving or declining in the residential sector (and separately in the commercial sector). In other words, are we making progress towards reducing overall energy consumption? Under this approach, states would be able to track the energy efficiency performance of residential and commercial buildings within their state compared to previous years. With this metric, States could easily see whether they are improving relative to their own baseline. State performance would be tracked using aggregate, state-level metrics.

The PSEP methodology and metrics have been featured as a chapter in the American Council for an Energy Efficient Economy (ACEEE) State Energy Efficiency Scorecard for 2009, 2010, and 2011.

Ground Truth Analyses

We have conducted a series of analyses we call “ground truth” reports to better understand the relationship between performance as measured by the PSEP metric and the history of residential sector energy consumption and residential efficiency policies in specific states.
