Electric utilities are required to achieve increasing cumulative persisting annual savings 2018-2026, reaching 17.9% in 2026 for utilities serving >3,000,000 retail customers, and 13.6% in 2026 for utilities serving between 500,000 and 3,000,000 retail customers. Savings are relative to average consumption over 2014-2016. Starting in 2027, utilities serving >3,000,000 retail customers must achieve 2% annual energy savings. Electric utilities serving between 500,000 and 3,000,000 retail customers must achieve annual energy savings equal to 1.4% in 2027, 1.7% in 2028, and 2% annually starting in 2029. Savings targets that start in 2027 are relative to average electricity sales from 2021-2023. Incremental annual energy savings may be reduced if a utility exceeds the requirement that 25% of total energy efficiency spending target low-income households. Gas utilities are required to achieve annual energy savings of 1.5% each year, with specific low-income energy efficiency spending requirements. Establishing Policies
