Bridging the Equity Gap for Utility Energy Efficiency Programs
Note: This report was updated on July 31, 2026, to reflect data from Commonwealth Edison received after publication that showed additional spending on low-income efficiency programs. Resultant updates to the analysis yielded an increase in the overall average spending (of all utilities in the sample) on low-income programs in 2024. This increased the average share of budgets dedicated to programming for low-income populations to 14.1% and reduced the average “equity gap” to 13.8%; each change was less than 1 percentage point. ComEd-specific results were updated throughout. Additionally, the per-household savings data for Baltimore Gas and Electric was corrected, and that resulted in BGE no longer being listed in the top quartile of utilities in that category.
