Massachusetts Solar

The Massachusetts market is driven by net metering, a renewable portfolio standard with a solar goal along with an accompanying SREC market. The state surpassed its goal of 400 MW four years ahead of schedule and has since set a new goal of 1.6GW by 2020. Net metering caps do not align with program goals, and the legislature has had to act three times to raise the net metering caps.  The caps in all of the Commonwealth's utility territories have been met, which has resulted in more than 240 MW of projects on hold
