In order to Net Meter, you must first apply to interconnect a generating facility through Unitil. We recommend you apply for interconnection prior to purchasing any equipment, since some modifications to the electric system may be necessary and paid for by the customer. When applying to interconnect, you should indicate if you are interested in Net Metering. Net Metering rules are defined by the state government and are different in each state, therefore, you should reference the your state's website.
