WORKSHOP
To: Board of Directors
From: Stephen Hollabaugh
Date: May 079 2008
Subject: D-NM Net Metering Schedule Update
1. WHY THIS MATTER IS BEFORE THE BOARD
The District schedules should periodically be reviewed and updated to conform to
current District Board policies and new applicable laws and regulations.
2. HISTORY
The Board of Directors has set Goal 5.3 in its Mission Statement that states the
District will support a program of distributed generation within its Service Area.
Schedule D-NM related to Net Metering enables distributed generation to use this
metering and billing schedule. The District has approved a SB1 (solar generation)
program that will enable more customers to install solar generation. The existing
schedule D-NM facilitates term-of-service to customers with solar and wind power
production systems of not more than ten kilowatts.
3. NEW INFORMATION
The District has been approached and has an application form a commercial
customer for a solar generation installation of more than ten kilowatts.
California Assembly Bill 58 has modified the Net Metering program. The Net
Metering program was expanded to include systems sized up to 1 megawatt (MW).
Staff proposes to revised and rename schedule D-NM to schedule NM and rescind
Ordinance 2000-01. With the program now available to up to 1 megawatt, domestic
and commercial customers may use this schedule. In order to alleviate any
confusion, the domestic portion of the old schedule name was dropped. The new NM
schedule has been changed to include installations up to 1 megawatt in size and the
billing description has been revised for clarity.
4. FISCAL IMPACT
The fiscal impact varies depending on participation and production.
5. RECOMMENDATION
Review this report and provide comments.
Staff would like to schedule a public hearing and action item for June 4, 2008.

Ordinance No. 2008-XX
Adopting Schedule NM, -Net Metering and Rescinding Ordinance No. 2000-01
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 customers 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 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 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 date
thereafter,be billed for electricity used during that period. The District will determine if the customer-
generator was a net consumer or a net producer of electricity during that period.
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 shall be paid in accordance with the normal billing cycle, except 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 a monetary value,
calculated according to the procedures set forth in this section, and appear as a credit on the customer-
generator's account until the end of the annual period when(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.
NOW THEREFORE,BE IT ENACTED by the Board of Directors that effective 30 days from the date of passage
of this ordinance,the District's Schedule D-NM,Domestic—Net Metering Tariff, shall become effective and that

APPLICABILITY
Applicable to domestic service to residential customers eligible for service where a part or all of the electrical
requirements of the customer can be supplied from a photovoltaic 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 customers 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,terns and conditions and the terms of inter-connection and parallel operation are

RATES
Service charge Per meter per month$4.00
Energy charge On the domestic rate applicable to that residence
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.
(b) Net energy:Net energy is ES minus EF where ES is energy supplied by the District and EF is energy
generated by the customer and fed back into the Districts system at such times as customer generation exceeds
customer requirements. Only if net energy is positive shall net energy charges be applied at the rates specified
above except that the minimum charge will be applied in any case. If the calculation of net energy yields a negative
result, all such negative net energy shall be considered net energy transmitted and shall be treated as stated in
special condition(c)below.The components of net energy,ES and EF shall be determined by the use of a single,
non-demand,non-time-differentiated meter to be provided by the District. If a new meter is required,then the
normal meter installation fee will be charged.
(c) Net energy transmitted:Net energy transmitted occurs when the cumulative value of EF exceeds the
cumulative value of ES during an entire billing period and is the amount by which the energy generated by the
customer and fed back into the districts system exceeds the energy supplied by the District over an entire billing
period. Such net energy transmitted will be purchased by the District at its monthly average non-firm energy price
the District pays during the applicable billing month.
(d) Billing and billing periods: The billing period to be used under this tariff shall be the customary monthly
billing period. In any monthly billing period where ES exceeds EF,the District will bill the customer for the net
energy consumed per the terms of the tariff.In monthly billing periods where EF exceeds ES,the District will pay
