Governed by the Maine Public Utilities Commission (PUC) Chapter 313 , the Net Energy Billing (NEB) program was established to encourage electricity generation from renewable sources in Maine. The rules establish the terms and requirements that the regulated utilities, Central Maine Power and Versant Power (formerly Emera), must offer Net Energy Billing.
Under the Net Energy Billing program, ratepayers can elect to have a shared financial interest in a solar project, up to 5MWac in size, through a Sunscription. The customer is then virtually connected to the offsite solar projects and receives a bill credit on their transmission and distribution utility bill. The bill credit is based on the annual tariff rates set by the PUC.
A Sunscription allows electric customers in one place to benefit from a solar project located somewhere else. When homes and businesses have a Sunscription to a Solar Garden, they can save.
