Net Excess Generation Notes

The Customer shall receive no compensation from the Company for Excess Generation during the monthly billing period. The Excess Generation during the monthly billing period shall be carried forward and credited against positive energy usage

The Net Metering Period shall be defined as each successive 12 month period beginning with the first meter reading date following the date of interconnection of the renewable fuel generator with the Company's facilities. Any Excess Generation at the end of a Net Metering Period shall be carried forward to the next Net Metering Period only to the extent that the Excess Generation does not exceed the Customer’s billed consumption for the current Net Metering Period, adjusted to exclude accumulated Billing Period Credits carried forward and applied from the previous Net Metering Period.

Upon written request of the Customer, the Company and the Customer shall enter into a power purchase agreement for the Customer’s Excess Generation for one or more Net Metering Periods. For Net Metering Periods beginning on or after January 1, 2009, the written request of the customer must be submitted prior to the beginning of the Net Metering Period.

The Company will purchase the Customer’s negative net energy for requested Net Metering Periods at aprice equal to the PJM Interconnection, L.L.C. (PJM) day-ahead annual, simple average LMP (locational marginal price).

At the time the power purchase agreement is signed - the Customer exercises Customer’s one-time option to include a provision in the power purchase agreement that requires the Company to purchase all generated RECs over the duration of the power purchase agreement.
