This first edition of the Utility Energy Efficiency Scorecard assesses the 51 largest US electric utilities across a range of energy efficiency metrics. The metrics fall into three categories critical to utility-sector efficiency: (1) quantitative savings and spending performance, (2) program diversity and emerging areas, and (3) targets, business models, and evaluation. Eversource MA and National Grid MA both performed best, tying for the top spot. The other top 10 utilities include Pacific Gas & Electric, Baltimore Gas & Electric, Eversource CT, Southern California Edison, San Diego Gas & and Electric, Commonwealth Edison, Portland General Electric, Xcel Colorado, and Xcel Minnesota. The Scorecard gives utilities, regulators, and other stakeholders a baseline and roadmap they can use to track performance and strengthen utility-sector energy efficiency.
