Massachusetts’ Green Communities Act requires that electric and gas utilities procure all cost-effective energy efficiency, which requirements the state’s PUC administers on a three-year planning cycle. Yearly incremental energy savings targets began at 1.4% in 2010, ramping up to 3.18% in 2017. Current targets for 2019-21, the fourth three-year planning cycle, are set at ~2.7% of retail sales, one of the highest targets in the country. The state’s natural gas targets began at 0.63% in 2010, and are set at 1.25% of retail sales for 2019-21. Overall, the fully funded 2019-2021 electric and natural gas efficiency procurement plans will yield net consumer benefits of nearly $8.56 billion.
