The Massachusetts market is driven by net metering and a renewable portfolio standard with a solar goal along with an accompanying SREC market. Net metering caps do not align with program goals, and the legislature has had to act several times to raise the net metering caps. The Massachusetts Department of Energy Resources is working on implementing a successor to the successful SREC program, and once again, net metering caps have been reached in certain utility territories.
