Pubhc Utility District H 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. Stephen HollabaughVssistant General Michael D. Holley, General Manager Manager 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 Ordinance No. 2000-01 be rescinded.

TERRITORY The entire area served by the Truckee Donner Public Utility District electric system. 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.
