E Source recently benchmarked 40 utility demand-side management (DSM) portfolios, gathering data on budgets, goals, spending, and energy savings from 2011. Portfolios were analyzed on whole as well as at the sector level for nonresidential, residential, and low-income programs. Using data from DSM annual reports, E Source found that 75 percent of program administrators achieved at least 90 percent of their electric or gas energy-savings goals.
“DSM goals have been exponentially increasing since 2009,” says Adam Maxwell, product manager for E Source Efficiency Services. “When you put it in the context of these unprecedented DSM goals, the fact that a large majority of administrators achieved 90 percent or more of their goals is remarkable. Utilities are finding innovative methods to get deeper energy savings per project and engage a wider range of customers with their energy use.”
Pacific Gas and Electric Co. (PG&E), Southern California Edison, and BC Hydro all saved more than 1 million megawatt-hours of electricity; PG&E and Southern California Gas Co. both saved over 3 million gross decatherms (Dth) of gas energy. The absolute energy-savings figures don’t tell the entire story: 18 electric utilities and 4 gas utilities achieved energy savings of at least 1 percent of their retail sales. “In this challenging economic climate and era of low natural gas prices, these numbers are truly astounding,” says Maxwell.
E Source analyzed key metrics such as overall energy savings (kilowatt-hours and Dth), energy savings as a percentage of retail sales, overall portfolio cost-effectiveness, and per-capita energy savings. For more information about E Source DSM benchmarking, please contact us.
