IPC-07- ) APPLICATION OF IDAHO POWER ) COMPANY IDAHO POWER COMPANY (the "Company" or "Idaho Power ) hereby applies to the Idaho Public Utilities Commission (the "Commission ) for authority to implement two time-variant energy pricing programs for customers in the vicinity of the cities of Emmett and Letha, Idaho ("Emmett Valley ). The Company proposes to offer Schedule 4 Energy Watch Program, for customers desiring to take electric service at critical peak pricing energy rates and Schedule 5 , Time-of-Day Program , for customers desiring to take electric service at time-of-use energy rates. The Company proposes both programs be offered to customers on an optional , voluntary basis. In support of this Application Idaho Power submits the following: APPLICATION OF IDAHO POWER COMPANY - Page BACKGROUND Both the Energy Watch and Time-of-Day Programs were approved as Pilot Programs in March 2005 in accordance with Commission Order No. 29737 issued in Case No. IPC-05-2. On May 9, 2006, the Commission approved Idaho Power request to extend both Pilot Programs for another year. In Order No. 30037 issued in Case No. IPC-06-, these Pilot Programs were approved as voluntary tariff options available to all residential customers in the Emmett Valley who had AMR metering installed. Under both Pilot Programs, the pricing for energy consumption during the months of June, July, and August included a time-variant component or components. For all other months , the pricing was identical to that for standard Residential Service under Schedule 1. In order to allow customers in the Emmett Valley continued choice in service schedules , and to allow the Company the opportunity to continue evaluating time- variant pricing and refining and implementing the internal systems used to collect and aggregate usage data and bill participants , the Company desires to continue offering these programs on a limited basis. II. PILOT PROGRAM RESULTS Information Gains The operation of the Pilot Programs in the past two years has provided valuable information. For both 2005 and 2006 , the Company contracted with consultants to conduct both a customer survey and an analysis of the usage and billing data APPLICATION OF IDAHO POWER COMPANY - Page 2 associated with these programs. The detailed results for the Pilot Programs' operation during 2005 were filed with the Commission on March 29, 2006. The detailed results for the Pilot Programs' operation during 2006 were filed with the Commission on February 28, 2007. The Company requests that the Commission take administrative notice of these filings in its consideration of this Application. Customer Satisfaction The results from the customer surveys indicate that overall, the participants in the Pilot Programs were satisfied with the programs.In 2005, 60 percent of the respondents indicated they were very likely to participate again. In 2006, the number of respondents who indicated they were very likely to participate again increased to 68 percent. Customer Cost Savings The analysis of the usage and billing data associated with the Pilot Programs suggests that on average , customers benefited by signing up for these time-variant pricing programs. Time-of-Day participants, on average, saved about 5 percent on their bills for 2005 and about 1 percent on their bills for 2006, for the summer months of June , July, and August, when compared to a control group with similar usage taking service under Schedule 1. Energy Watch participants, on average , saved about 10 percent in 2005 and 12 percent in 2006 , when compared to a control group with similar usage patterns taking service under Schedule 1. APPLICATION OF IDAHO POWER COMPANY - Page 3 Load Shifting Although the Time-of-Day participants did not demonstrate a statistically significant shift in load , a slight difference in usage patterns for this group compared to the control group was apparent.The Energy Watch participants , on average however, did demonstrate a statistically significant demand reduction during Energy Watch hours. On average , the Energy Watch participants reduced their household demand by 1.33 kW for all Energy Watch hours in 2005 and by 1.26 kW for all Energy Watch hours in 2006. Participant Retention The participant retention rate for both Pilot Programs was fairly high. In 2005, the Energy Watch program began with 79 participants and retained 76 by the end of August 2005. In 2006, the Energy Watch program began with 75 participants and ended with 68 participants.In 2005, the Time-of-Day program began with 95 participants and retained 93 participants. In 2006, the Time-of-Day program began with 85 participants and retained all 85 participants. Based on the results of the Pilot Programs, including the high level of customer satisfaction , the Company is proposing to maintain the same program design and pricing going forward as that implemented for the Pilot Programs during the summer of 2006. III. SCHEDULE 4 ENERGY WATCH PROGRAM DESCRIPTION The Energy Watch Program will provide customers the opportunity to reduce their electric bills by shifting usage off of "critical peak" hours , or hours when the cost to provide energy is extremely high , and onto other hours of the day for which the cost to APPLICATION OF IDAHO POWER COMPANY - Page 4 provide energy is lower. The Energy Watch Program will be available to all residential customers in the Emmett Valley not participating in the A/C Cool Credit program whose energy usage equals or exceeds 300 kWh for each of the most recent 12 consecutive billing periods (or for all billing periods if the customer has less than 12 months of billing history). Under the Energy Watch Program, residential customers will be charged a flat energy rate for all kWh used during the summer season with the exception of the kWh used during an Energy Watch Period. During Energy Watch Periods, the Company is proposing the energy rate be substantially higher than the energy rate for all other hours. Energy Watch Periods can occur on any weekday from June 15 through August , except for Independence Day when it falls on a weekday. Energy Watch Periods will be determined by the Company. The Company will notify Program participants of the declared Energy Watch Period by 4:00 p.m. the day ahead by telephone and email. All Energy Watch Periods will be for the hours of 5:00 to 9:00 p.m. Energy Watch Periods will occur on no more than 10 days from June 15 to August 15 , for a total of 40 hours. The summer and non-summer seasons for the Energy Watch Program will be defined the same as under Schedule 1 , with the summer season beginning on June and ending on August 31. The Company proposes to establish the base energy rate for the Energy Watch Program equal to the first block Energy Charge under Schedule 1. The proposed Energy Charge during Energy Watch Periods is 20 cents per kWh. The proposed rates are: APPLICATION OF IDAHO POWER COMPANY - Page 5 Summer Base Rate Energy Watch Period 20.0000q; per kWh 5.4251q; per kWhAll other Hours Non-Summer Base Rate All hours 5.4251q; per kWh Customers participating in the Energy Watch Program will continue to pay the monthly Service Charge of $4.00. IV. SCHEDULE 5 TIME-OF-DA Y PROGRAM DESCRIPTION The Time-of-Day Program will provide customers the opportunity to reduce their bills by shifting usage from the "on-peak" period , when the cost to provide energy is highest , to the "off-peak" period, when the cost to provide energy is the lowest. The Company proposes the Time-of-Day pricing periods be in effect during the summer season only. During the non-summer season , the pricing would be the same as that under Schedule The Time-of-Day program will be available to all residential customers in the Emmett Valley except those who participate in the A/C Cool Credit program. Time-of-Dav Periods Under the Time-of-Day Program, residential customers are provided price signals to encourage them to shift their energy usage to specific periods of the day. The three proposed Time-of-Day pricing periods for the summer season are defined as: On-Peak:1 :00 p.m. to 9:00 pm. Monday - Friday, except for Independence Day when it falls on a weekday APPLICATION OF IDAHO POWER COMPANY - Page 6 Mid-Peak:7:00 a.m. to 1 :00 p.m. Monday through Friday, except for Independence Day when it falls on a weekday Off-Peak:9:00 p.m. to 7:00 a.m. all days and all hours Saturday, Sunday, and ndependence Day The summer and non-summer seasons will be defined the same as under Schedule 1 , with the summer season beginning June 1 and ending August 31. Time-of-Dav Rates The Company proposes that customers be charged a different energy rate for each of the three Time-of-Day pricing periods. For all usage during the non-summer period , the Company proposes that customers be charged the same energy rate as is charged under Schedule 1. The Company is proposing the following rates for each of the Time-of-Day pricing periods. Summer Base Rate On-Peak Mid-Peak 3279ct per kWh 1060ct per kWh Off-Peak 5145ct per kWh Non-Summer Base Rate All hours 5.4251 ct per kWh Customers participating in the Time-of-Day Pilot Program will continue to pay the monthly Service Charge of $4.00.
