Net Energy Billing
The Maine Public Utilities Chapter 313 rule governs net energy billing in Maine. The Chapter was established to help implement the State’s policy to encourage electricity generation from renewable resources through small independently owned generation sources thus allowing customers to produce electricity for their own use. The rule establishes the terms and requirements under which regulated utilities within the State must implement net energy billing. Please refer to Chapter 313 (see link below) for details.
- Customer must be located within the utility’s service territory.
- An eligible facility must have a nameplate capacity that is less than 5 MWAC.
- Municipalities may have an eligible facility with a nameplate capacity greater than 5 MWAC, however no more than 4.999 MWh can be used for net metering. Generation above that level will be used to offset system losses and no credit will be applied to the customer.
- Energy generated from an eligible facility must qualify as a renewable fuel source or technology as specified in 35-A M.R.S.A. §3210(2)(C). These include fuel cells, tidal power, solar, wind, geothermal electricity production, hydroelectric, biomass that are fueled by wood or wood waste, landfill gas, anaerobic digestion of agricultural products or by-products or generators fueled by municipal solid waste in conjunction with recycling. New micro-combined heat and power systems are no longer allowed to net meter.
Net Meter Application
- Customer’s wishing to net energy bill must fill out a net metering Chapter 313 application in addition to the Chapter 324 application for an Interconnection Agreement and submit to CMP prior to commencement of the service under the rule.
