  1. NPPD Net Metering Policy Wind Power 2008 Conference November 11, 2008 Dave Rich

  2. Net Metering Qualifications • NPPD customer that has a generation facility (or facilities) interconnected behind their service meter. • Aggregate nameplate capacity of 25 kW or less. • Federal Energy Regulatory Commission (FERC) certification as a Qualifying Facility (QF) under the Public Utility Regulatory Policies Act (PURPA). • Rate schedule will be made available to new Customers until the aggregate nameplate capacity of participating Customer generation reaches 1% of the peak annual demand of the District’s retail customers. Currently have 4 kW with approximately 6,000 kW aggregate limit.

  3. Billing Procedure • Customer will be allowed to use the electrical output of their generator to supply all or a portion of their own load and deliver any surplus to NPPD. • If over the billing period there is a net flow of energy from the District to the Customer, the Customer will be billed for the net use at rates included in their applicable standard rate schedule. • If over the billing period there is a net flow of energy from the Customer to the District [i.e. Net Excess Generation (NEG)], the Customer will be billed for the non-energy charges included in their applicable standard rate schedule, and: • a monetary credit for such NEG will be determined and carried forward to the subsequent billing period as an offset to future energy charges. • if at the end of the calendar year an amount is owed to the Customer for accumulated monetary credits associated with NEG, then such amount will be paid to Customer.

  5. Terms & Conditions • Customer shall comply with all applicable notification, interconnection, approvals, and other requirements established under NPPD’s Distributed Generation (DG) Interconnection Standard. • If Customer’s existing meter is capable of providing the information necessary to take service under this rate schedule and the District opts to replace the meter with one capable of measuring the flow of energy in each direction, then the cost of such replacement meter will be borne by the District. • Customer must submit proof to the District of FERC certification as a QF prior to taking service under this rate schedule. • Customer shall maintain ownership of all current and future attributes of an environmental nature (e.g., green tags) associated with the output of their generation.

  6. Net Metering Impacts on Small Wind • USDA approved two grants for small wind. • one connected to a utility with net metering • one connected to a utility without net metering • The simple payback was calculated to be 40+ years for both projects. • Summary – Net metering may not significantly impact the payback.
