TWEETS

Full retail credit with no subtractions. Customers protected from fees and additional charges. Rules actively encourage use of DG.

A

Generally good net metering policies with full retail credit, but there could be certain fees or costs that detract from full retail equivalent value. There may be some obstacles to net metering.

B

Adequate net metering rules, but there could be some significant fees or other obstacles that undercut the value or make the process of net metering more difficult.

C

Poor net metering policies with substantial charges or other hindrances. Many customers will forgo an opportunity to install DG because net metering rules subtract substantial economic value.

D

Net metering policies that deter customer-sited DG.

Eligible Renewable/Other Technologies

Geothermal Electric, Solar Thermal Electric, Solar Photovoltaics, Wind (All), Biomass, Hydroelectric, Municipal Solid Waste, Combined Heat & Power, Fuel Cells using Non-Renewable Fuels, Wind (Small), Hydroelectric (Small), Anaerobic Digestion, Fuel Cells using Renewable Fuels, Other Distributed Generation Technologies

Applicable Sectors

Commercial, Industrial, Local Government, Nonprofit, Residential, Schools, State Government, Federal Government, Agricultural, Institutional

Applicable Utilities

Investor-owned utilities

System Capacity Limit

10 MW for net metering by a municipality or other governmental entity; 2 MW for all other "Class III" systems; 1 MW for all other "Class II" systems; 60 kW for all other "Class I" systems

Aggregate Capacity Limit

7% of utility's peak load for private entities; 8% of utility's peak load for municipalities or governmental entities. Systems 10 kW and under on a single-phase circuit and systems 25 kW and under on a three-phase circuit are exempt from the private aggregate capacity limit.

Net Excess Generation

Varies by system type and customer class

REC Ownership

Customer owns RECs

Meter Aggregation

Neighborhood net metering allowed

recommendations

  • Improve net excess generation credit rate for non-residential, non-governmental customers

notes

Massachusetts has established a complex policy that includes three different classes of systems, with certain policy provisions varying by system class. In 2016, state law increased aggregate capacity limits to 7% (private - excluding residential) and 8% (public). However, the net excess generation credit rate was reduced for most privately owned solar systems, beginning once the state reaches 1,600 MW in aggregate capacity. Significantly, the Massachusetts policy explicitly allows neighborhood net metering, a shared renewable-energy arrangement, and third-party ownership of systems. Interestingly, Massachusetts has established a System of Assurance of Net Metering Eligibility, an online tool that enables customers to apply for and reserve space for a planned system under the established aggregate program cap. This site provides real-time updates and detailed information on cap allocations provided, including historical reports on available capacity under the established program cap.
