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 approved in 2018 and has the potential to drive significant solar deployment in the state, and act as a template for other states to follow.
