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

Solar Thermal Electric, Photovoltaics, Wind, Biomass, Hydroelectric, Geothermal Electric, Fuel Cells, Municipal Solid Waste, CHP/Cogeneration, (CHP/Cogeneration since April 30, 2009), Small Hydroelectric, Tidal Energy

Applicable Sectors

Commercial, Industrial, Residential

Applicable Utilities

All utilities

System Capacity Limit

660 kW for IOU customers; 100 kW for muni and co-op customers (although they may offer up to 660 kW voluntarily)

Aggregate Capacity Limit

No limit specified

Net Excess Generation

Credited to customer's next bill at retail rate; granted to utility at end of 12-month billing cycle

REC Ownership

Not addressed

Meter Aggregation

Allowed

recommendations

  • Remove system size limitations to allow customers to meet all on-site energy needs Adopt safe harbor language to protect customer-sited generators from extra and/or unanticipated fees

notes

Maine is one of a handful of U.S. states that allows virtual net metering and net metering for shared renewable-energy systems. While Maines policy is generally good, it currently does not address REC ownership or include _safe harborî language to protect net-metering customers from potential fees and charges that would not apply to other customers. Indeed, CMP, an investor-owned utility, has proposed a new standby charge for customers who generate their own electricity. CMPs proposal is part of a larger rate case under consideration by the Maine Public Utilities Commission.
