PRODUCTION REQUEST OF THE) coMMrssroN STAFF To |DAHO ) POWER COMPANY ) COMES NOW, ldaho Power Company ("ldaho Powe/' or "Company"), and in response to the Fourth Production Request of the Commission Staff to ldaho Power Company dated September 3,2013, herewith submits the following information: IDAHO POWER COMPANY'S RESPONSE TO THE FOURTH PRODUCTION REQUEST OF THE COMMISSION STAFF TO IDAHO POWER COMPANY. 1 REQUEST NO. 17: Please explain how the Company calculates a customer's excess net energy when the customer has multiple meters on one or more rate schedule at one or more premises. As part of your response, please explain how the Company tracks these situations in its billing system and ultimately calculates the bill. To the extent this will change when the new billing system is deployed, please explain the changes. RESPONSE TO REQUEST NO. 17: Customers who own or operate a generation facility and take service under Schedules 1 or 7 have a single meter installation which records the electricity supplied by the Company by advancing the register read and the electricity delivered by the Seller to the Company, if any, by reversing the register read. When the electricity delivered by the Seller is greater than the electricity supplied by the Company, the billing system calculates negative consumption or Excess Net Energy from the register read. Any Excess Net Energy generated during the billing period is financially credited to the Seller at the standard service schedule retail rates for the applicable schedule (Schedule 1 or Schedule 7). Customers who own or operate a generation facility and take service under a schedule other than Schedules 1, 4, 5, or 7 have a dual meter installation. Electricity supplied by the Company is recorded through the retail load meter while the electricity generated by the Seller and delivered to the Company is recorded through a separate meter. Both meters are installed at a single service point and are associated with a single rate schedule. The kilowatt-hour ("kwh') recordings for both meters are netted during the billing process to determine either the amount of kWh to be billed to the customer under the standard service schedule or the amount of kWh (Excess Net IDAHO POWER COMPANY'S RESPONSE TO THE FOURTH PRODUCTION REOUEST OF THE COMMISSION STAFF TO IDAHO POWER COMPANY - 2 Energy) to receive a financial credit equal to 85 percent of the most recently calculated monthly per kWh Avoided Energy Cost. Regardless of the schedule under which a net metering customer takes service, any Excess Net Energy is applied only to the specific service point to which the Selle/s generation facility is connected. There is no tracking of Excess Net Energy required as any Excess Net Energy is financially credited on the customeds bill each month. The customer can choose to let the credit carry over to the next month or can request the Company refund the credit via check. New Billinq Svstem - The new billing_ system currently bills net metering service the same way it was billed within the old billing system. Because financial crediting is in place today there is currently no need to track Excess Net Energy on an ongoing basis. The new billing system wil! need to be reconfigured to track Excess Net Energy. The specific details regarding the changes are in the process of being identified. The response to this Request is sponsored by Mathew Larkin, Regulatory Analyst, ldaho Power Company. IDAHO POWER COMPANY'S RESPONSE TO THE FOURTH PRODUCTION REQUEST OF THE COMMISSION STAFF TO IDAHO POWER COMPANY - 3 REQUEST NO. 18: Please explain the capabilities of the Company's new billing system with regard to net metering aggregation. Specifically, for customers having a separate meter from the existing retail load, please explain if the new billing system can net usage across multiple schedules and customer accounts. RESPONSE TO REQUEST NO. 18: The Company's new billing system is not able to net usage across multiple schedules and customer accounts. Manual billing processes would need to be developed should it be necessary to net usage across schedules, service points, or accounts. The response to this Request is sponsored by Mathew Larkin, Regulatory Analyst, ldaho Power Company. IDAHO POWER COMPANY'S RESPONSE TO THE FOURTH PRODUCTION REQUEST OF THE COMMISSION STAFF TO IDAHO POWER COMPANY - 4 REQUEST NO. 19: The Company's Schedule 84 compliance tariff says service applies to "a Generation Facility with a total nameplate capacity rating of 100 kilowatts (kW) or smaller that is interconnected at a Generation lnterconnection Point that is adjacent to the Customer's Point of Delivery." Please explain what "adjacent" means as used in this tariff. As part of your response, please explain if a Generation lnterconnection Point must be within a certain distance of the customer's Point of Delivery before the Company considers it "adjacent." Also, if one customer has several Points of Delivery, please explain whether one Generation lnterconnection Point can be considered "adjacent" to multiple Points of Delivery. RESPONSE TO REQUEST NO. 19: Within the context of a two-meter net metering configuration, the term "adjacent" means the second meter must share a common interconnection point with the customer's standard retail Point of Delivery, though the exact location of the second meter will vary based on the setup of each individual custome/s electrical service. Some customers, for example, will install the second meter immediately above or below the existing billing meter, while others will connect at the weather head where the billing meter connects to the transformer. Based on this definition it is not possible for a customer to have a Generation lnterconnection Point that is "adjacent" to multiple Points of Delivery, as the second meter must connect at the same Point of Delivery as the retail service associated with the generation facility.
