Energy Efficiency Resource Standards (EERS)

In recent years, states have been actively updating and expanding their Energy Efficiency Resource Standards (EERS), which require utilities to achieve a certain percentage of energy savings based on the amount of electricity or natural gas sold in the state. States have implemented these long-term efficiency goals to decrease electricity and natural gas consumption and promote efficient technologies that reduce pollution associated with energy generation and use. A recent analysis by the American Council for an Energy-Efficient Economy found that in 2017, states with an EERS achieved annual incremental savings of 1.2% of retail electricity sales on average; by comparison, states without an EERS only achieved savings of 0.3%.  

Texas adopted the first EERS standards in 1999 and since then, 27 other states have successfully implemented EERS programs that remain in place today, with New Hampshire and New Jersey being the most recent. Some of the more recent state revisions to EERS policies include expanding standards to require efficiency targets for natural gas and extending standards to require efficiency targets in future years. For example, in 2019 Washington for the first time expanded its EERS to include requirements for natural gas utilities and New Mexico enacted legislation requiring that the state set efficiency targets for 2026 through 2030 no later than 2025. While most recent state action has targeted updating or expanding EERS policies, a few states, including Florida and Indiana, effectively eliminated their EERS programs in 2014.
