Alternative Energy Portfolio Standard
Quick Summary
The Alternative Energy Portfolio Standard does not directly offer incentives to homeowners; instead, it is a regulatory requirement that utilities and retail suppliers must meet 5% of Massachusetts' electric load with alternative energy sources (such as combined heat and power, geothermal heat pumps, and biomass) by 2020, with further increases of 0.25% annually afterward. You may indirectly benefit if utility compliance costs are passed through rates or if utilities invest in alternative energy infrastructure serving your area.

These projects must be new (start date after January 1, 2008) and must receive a statement of qualification from the Department of Energy Resources to qualify.
