This second edition of the Utility Energy Efficiency Scorecard assesses the 52 largest US electric utilities across a range of energy efficiency metrics. The metrics fall into three categories critical to utility-sector efficiency: (1) energy efficiency program performance, (2) program offerings and portfolio comprehensiveness, and (3) enabling mechanisms for efficiency. Eversource MA and National Grid MA both performed best, tying for the top spot. The other top 10 utilities include San Diego Gas & and Electric, Commonwealth Edison, Baltimore Gas & Electric, Pacific Gas & Electric, Los Angeles Department of Water and Power, DTE, Portland General Electric, and Eversource CT. Since the previous edition, utilities have dramatically ramped up energy savings, increased their focus on helping low-income communities save energy, and begun to invest in promoting electric vehicles. The Scorecard gives utilities, regulators, and other stakeholders benchmarking data and a roadmap they can use to track performance and strengthen utility-sector energy efficiency.
