APPENDIX D
SCHEDULE D-NM
DOMESTIC - NET METERING
APPLICABILITY
Applicable to residential or commercial customers eligible for service where a part or all of the
electrical requirements of the customer can be supplied from a solar or wind power production
source owned and operated by the customer, where such source is connected for parallel operation
with the service of the District and where such source is located on the customer’s premises and is
intended to offset part or all of the customers electrical requirements.
This schedule provides rates, terms and conditions for the sale of energy by the District. Prices,
terms and conditions for the purchase of net energy transmitted by the customer to the District are
included herein for reference only. Such prices, terms and conditions and the terms of inter-
connection and parallel operation are outlined in the generation agreement required for service under
this tariff. The purpose of this tariff is to facilitate terms of service to customers with solar or wind
power production systems of not more than one megawatt.
Applicability of this tariff does not extend to customers whose solar or wind power production source
exceeds 1000 kilowatts or one megawatt.
TERRITORY
The entire area served by the Truckee Donner Public Utility District electric system.
RATES
Customer charge Same as applicable residential or commercial customer charge.
Energy charge On the residential or commercial energy rate applicable to that customer.
Net energy credit All kilowatt-hours, per kilowatt-hour — the net energy credit will be computed
at a rate for payment equal to the monthly average non-firm energy price the
District pays during the applicable billing month.
SPECIAL CONDITIONS
(a) Generation agreement: A generation agreement with the customer is required for service
under the schedule.
For eligible residential and small commercial customer-generators, the net energy metering
calculation shall be made by measuring the difference between the electricity supplied to the eligible
customer-generator and the electricity generated by the eligible customer-generator and fed back to
the electric grid over a 12-month period. The following rules shall apply to the annualized net
metering calculation:
1. The eligible customer-generator account shall, at the end of the 12-month period following
the date of final interconnection of the customer-generator’s system with the District, and at
each anniversary month thereafter, be evaluated and reconciled for electricity used or
generated during that period. The District will determine if the customer-generator was a net
consumer or a net producer of electricity during that period.
A. This evaluation and reconciliation for electricity used or generated may be
standardized by the District for the 12 month billing period ending with the March
billing, rather than using each customer’s respective anniversary month.
1
2. At the end of each 12-month period, where the electricity supplied during the period by the
District exceeds the electricity generated by the customer-generator during that same period,
the customer-generator is a net electricity consumer and the District shall be owed
compensation for the customer-generator’s net kilowatt-hour consumption over that same
period. The compensation owed for the customer-generator’s shall be calculated as follows:
The net balance of moneys owed to the District shall be paid in accordance with the
normal billing cycle. If the customer-generator is a net producer over a normal billing
cycle, any excess kilowatt-hours generated during the billing cycle shall be carried over to
the following billing period as kilowatt-hour credits according to the procedures set forth
in this section, and appear as a credit on the customer-generator’s account. This credit
may be utilized in the following billing cycle if the customer is a net consumer during that
cycle. If the customer is a net generator at the end of each 12-month period, then (3)
shall apply.
3. At the end of each 12-month period, where the electricity generated by the customer-
generator during that 12-month period exceeds the electricity supplied during that same
period, the customer-generator is a net electricity producer and the District shall retain any
excess kilowatt-hours generated during the prior 12-month period. The customer-generator
shall be compensated by the District for the excess kilowatt-hours generated at its annual
average non-firm energy price the District pays during the prior 12-month period.
4. If a customer-generator terminates the customer relationship with the District, the District
shall reconcile the customer-generator’s consumption and production of electricity during any
part of a 12-month period following the last reconciliation and shall apply only the months
since the most recent 12-month reconciliation.
