The Massachusetts market is shaped by net metering and a renewable portfolio standard with a solar goal, along with an accompanying SREC market. The Solar Massachusetts Renewable Target (SMART) program was established in 2018 and has driven significant solar deployment in the state, acting as a template for other states to follow.

Recent Policy Highlights

  • SEIA led efforts to expand the SMART program, helping secure an additional 1,600 megawatts of capacity for the program and relax some of the most onerous restrictions on developing solar projects on natural and working lands.
  • SEIA continued to support the Northeast Clean Energy Council's intervention with the Department of Public Utilities in case 19-55 on improving distributed solar interconnection policies.
  • SEIA also led efforts to extend project completion timelines based on the COVID crisis.
