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.  Current caps in certain utility territories are expected to be reached again in 2015.

Support Solar in Massachusetts
A comprehensive solar energy bill (H.4185) was recently introduced into the Massachusetts legislature. If passed, the bill will encourage more Bay Staters to go solar by removing the state’s caps on net metering, and by redesigning the state incentive program. Urge state lawmakers to keep solar shining by passing H.4185!
