Report Shows How Utilities Stack Up on Energy Efficiency
With cumulative annual energy efficiency savings equivalent to 16–17 percent of their annual retail electric sales in 2012, PG&E, Edison International and Northeast Utilities topped the list of energy performers in a new report released by Ceres and Clean Edge.
“Benchmarking Utility Clean Energy Deployment” assembles data from more than 10 sources and ranks 32 of the largest US investor-owned electric utility holding companies on three clean energy indicators.
Bottom ranking companies on energy efficiency included PSEG, SCANA, Pepco Holdings, Dominion Resources and Entergy. Cumulative annual energy efficiency savings for each of these companies accounted for less than one percent of their annual retail sales.
The report also ranks utilities’ renewable energy sales and incremental energy savings. NV Energy, Xcel Energy, PG&E, Sempra Energy and Edison International ranked the highest for renewable energy sales, while SCANA, Southern Company, Dominion Resources, AES and Entergy ranked at the bottom.
Pinnacle West, Sempra Energy, Portland General Electric, Puget Sound Energy and Northeast Utilities performed the best on incremental energy efficiency savings with each achieving savings of approximately 1.5 percent of retail electric sales. Bottom performers on incremental energy efficiency included Dominion Resources, PSEG, Entergy, FPL and Southern Co.
Many of the top-performing utilities in both renewable energy sales and energy efficiency savings are based in states and regions with aggressive clean energy policy goals, while utilities delivering less are often based in states with weak support for clean energy. California, for example, ranks high for overall clean energy policies and its utilities perform particularly well on both renewable energy and energy efficiency measures. Utilities with weaker deployment of clean energy are located in the Southeast, which historically has had weak state-level support for clean energy.
However, strong state-level policies are not the only factor in a utility’s investment in clean energy. The report found a range of performance even among utilities in similar market and regulatory environments.
