Energy delivered by the utility to the customer at the meter, as reflected in the meter reading, shall be billed at the appropriate utility full retail energy rate. For any excess energy generated by the customer from an approved on-site generating facility and delivered by the customer to the utility at the meter, as reflected in the meter reading, a credit shall be created and applied to the customer’s bill based upon the lesser of the full retail energy rate for the customer class and the avoided cost of energy. Unused credits earned and apply those credits to subsequent billing periods until all credits are used or until the end of the annual period. At the end of the annual period, any remaining credits in the customer's account shall expire and no credit or payment shall be due to the customer for such expired credits
