The Maine Legislature created rules for “net energy billing” in 2011. System size was limited to 660 kilowatts and a maximum of 10 participants were allowed per facility.
Under Maine’s net metering system, participants are required to have actual ownership of the generation facility. Flexible participation models are precluded, meaning no leasing or temporary subscriptions are allowed.
Maine expanded net energy billing in 2019 through L.D. 1711, raising the limit on community solar garden capacity to five megawatts and directing the PUC to establish a commercial solar tariff program to generate 350 megawatts of energy.
