Net Excess Generation Notes

Customer-owned renewable generation shall be first used for Customer’s own load and shall offset Customer’s demand for electricity from the Utility. All electric power and energy delivered by Utility to Customer shall be received and paid for by Customer pursuant to the terms, conditions and rates of the Utility’s applicable rate schedules.

Excess customer-owned renewable generation shall be delivered to the Utility’s electric distribution system. For purposes of this Agreement, the term “excess customer-owned renewable generation” means any kilowatt-hours of electrical energy produced by the customer-owned renewable generation system that is not consumed by Customer and is delivered to Utility’s electric distribution system. PMPA agrees to purchase and receive, and Customer agrees to sell and deliver, all excess customer-owned renewable generation at the energy rate established by PMPA, which shall be calculated in accordance with Schedule A. Excess customer-owned renewable generation shall be billed in the form of a credit on Customer’s monthly electricity consumption bill from Utility. 

In the event that a given monthly credit for excess customer-owned renewable generation exceeds the total billed amount for Customer’s consumption in any corresponding month, then the excess credit shall be applied to the subsequent month’s bill. Excess energy credits so produced shall accumulate and be used to offset Customer’s energy consumption bill for a period of not more than twelve (12) months. At the end of each calendar year, unused excess credits shall be paid by Utility to the Customer.
