IPC-06- 1:::0 APPLICATION IDAHO POWER COMPANY (the "Company" of "Idaho Power") hereby applies to the Idaho Public Utilities Commission (the "Commission ) for authority to continue two time-of-use energy pricing Pilot Programs for customers in the vicinity of the cities of Emmett and Letha, Idaho ("Emmett Valley ). The Company proposes to continue offering Schedule 4 , Energy Watch Pilot Program, to customers desiring to take electric service at critical peak pricing energy rates and Schedule 5, Time-of-Day Pilot Program , to customers desiring to take electric service at time-of-use energy rates. Hereafter, the two time-of-use pricing programs are collectively referred to as the "Pilot APPLICATION , Page Programs . The Company proposes to offer customers who participated in the Pilot Programs in 2005 the opportunity to continue their participation in 2006 if they so choose. The Company also intends to solicit new participants. Since these Pilot Programs are currently scheduled to expire on April 1 , 2006, the Company also requests that the Commission process this Application on an expedited basis or, in the alternative , issue an interlocutory order extending the effectiveness of the Pilot Programs for a sufficient time for the Commission to fully consider the Application to extend the programs for an additional year. In support of this Application , Idaho Power submits the following: BACKGROUND Both Schedule 4, Energy Watch Pilot Program , and Schedule 5, Time-of- Day Pilot Program , were approved in March 2005 in accordance with Order No. 29737 issued in Case No. IPC-05-2. These Pilot Programs are voluntary tariff options available to all residential customers in the Emmett Valley who have AMR metering installed. To evaluate the Time-of-Day and Energy Watch Pilot Programs, the Company retained Northwest Research Group to conduct a customer survey and RLW Analytics to analyze the usage and billing data associated with these programs. The detailed results of these Pilot Programs will be included in the Company s report to be submitted to the Commission on or before April 1 , 2006 in compliance with Order No. 29737. APPLICATION , Page 2 The preliminary evaluation of these Pilot Programs from the Northwest Research Group customer survey indicates that overall , the participants in these programs were satisfied with the programs. Sixty percent of the respondents indicated that they would participate again and 50 percent responded that they would recommend these programs to others. RLW Analytics' preliminary results of these programs suggest that on average customers benefited by signing up for these programs. Time-of-Day participants , on average, saved about 5 percent on their bills 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 when compared to a control group with similar usage patterns taking service under Schedule 1. The energy load shift, or decrease in usage, for the Time-of-Day participants , although apparent , was not statistically significant. The Energy Watch participants , on average , demonstrated 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. The participant retention rate for both programs was fairly high. The Energy Watch program began with 79 participants and retained 76 by the end of August 2005. The Time-of-Day program began with 95 participants and retained 92. The Company is requesting that these programs be extended to allow Idaho Power to further evaluate the impacts and benefits of time-variant pricing to residential customers , to evaluate customer retention , to test ongoing demand reduction and load shifting provided by customers, to refine the Company s marketing and APPLICATION , Page 3 communication plans , and to further test the internal systems used to collect usage data, aggregate usage data, and bill participants. II. AVAilABILITY The Pilot Programs offered by Idaho Power in 2005 will expire on April 1 2006 unless extended by the Commission. This Application is intended to extend these Pilot Programs until April 1 , 2007. Residential customers eligible to participate in the voluntary Pilot Programs will continue to be those customers in the Emmett Valley eligible for service under Schedule 1 who have AMR metering in place. The Company will provide those customers who participated in the programs during 2005 an opportunity to continue their participation during 2006. Additional customers wishing to participate will be selected on a first-come , first-served basis as determined by the Company. However, in order to improve the Company s ability to manage the usage data and the participants' potential to benefit from the Pilot Programs, program participation will be limited to those customers 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. Customers desiring to take service under the Time-of-Day Pilot Program or the Energy Watch Pilot Program will be required to notify Idaho Power of their desire to participate by May 19 , 2006. The cumulative enrollment under both Pilot Programs will be limited to 300 metered service points, unless the Company chooses to waive this restriction. The Company desires to enlist approximately 150 customers for each Pilot APPLICATION , Page 4 Program. However, if interest is greater for one Pilot Program than for the other, the Company may accept more volunteers for one Pilot Program than for the other in order to enroll up to 300 total metered service points. Under both of these Pilot Programs, the energy rates for the summer season would differ from the summer season energy rates under Schedule1. Energy rates for the non-summer months would be the same as those on Schedule 1. Those customers who choose not to participate in the Pilot Programs will continue to receive service under Schedule 1 , Residential Service. Customers remaining on the current residential schedule will not be economically disadvantaged by the participation of other residential customers in the Pilot Programs. III. SCHEDULE 4 ENERGY WATCH PILOT PROGRAM DESCRIPTION The Energy Watch Pilot Program provides 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 provide energy is lower. Since the preliminary results of the Energy Watch Pilot Program show a significant demand reduction and a financial benefit for most participants , the Company is not proposing any changes to the Energy Watch Pilot Program other than the change to the availability provision previously described. During the second year of the Pilot Program , the Company intends to investigate whether the demand reduction by the APPLICATION , Page 5 participants under the Energy Watch Pilot Program is sustainable over more than one summer season. EnerQY Watch Periods Under the Energy Watch Pilot Program , residential customers are 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. Energy Watch Periods can occur on any weekday from June 15 through August 15, except for Independence Day when it falls on a weekday. Energy Watch Periods are determined by the Company. The Company notifies Pilot Program participants of the declared Energy Watch Period by 4:00 p.m. the day ahead by telephone and email. All Energy Watch Periods are for the hours of 5:00 to 9:00 p.m. Energy Watch Periods can occur on no more than 10 days from June 15 to August 15, for a total of 40 hours. During Energy Watch Periods, the energy rate is substantially higher than the energy rate for all other hours. Under the Energy Watch Pilot Program , the summer and non-summer seasons are defined the same as under Schedule 1 , with the summer season beginning on June 1 and ending on August 31. The Company proposes to keep the base energy rates for the Energy Watch Pilot Program the same as those currently approved. Those rates are: Summer Base Rate Energy Watch Period 20.00001t per kWh All other Hours 5.42801t per kWh Non-Summer Base Rate All hours 5.42801t per kWh APPLICATION , Page 6 Customers participating in the Energy Watch Pilot Program will continue to pay the monthly Service Charge of $3.30. IV. SCHEDULE 5 TIME-OF-DA Y PILOT PROGRAM DESCRIPTION The Time-of-Day Pilot Program provides 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 1. The Company is proposing to change the rates for the Time-of-Day pricing periods and to modify the availability provision as previously described. The current Time-of-Day pricing has a 30 percent differential between "on-peak" and "off-peak" rates with an 11 percent differential between "on-peak" and "mid-peak". The proposed Time- of-Day pricing has an 80 percent differential between "on-peak" and "off-peak" rates with a 32 percent differential between "on-peak" and "mid-peak". By increasing the differentials between Time-of-Day pricing periods , the Company intends to increase the financial incentive for customers to shift their energy usage. The preliminary analysis of customer usage and benefits indicates that although on average Time-of-Day customers benefited from participating in the program, increased incentives may increase usage shifting. APPLICATION , Page 7 Time-of-Dav Periods Under the Pilot Program , residential customers would be provided price signals to encourage them to shift their energy usage to specific periods of the day. The three 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 Mid-Peak:7:00 a.m. to 1 :00 p.m. Monday through Friday, except for ndependence 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 are defined the same as under Schedule 1 , with the summer season beginning June 1 and ending August 31. Time-of-Dav Rates The proposed base energy rates for the Time-of-Day Pilot Program are: Summer Base Rates On-Peak 2423ct per kWh Mid-Peak 2334ct per kWh 5053ct per kWhOff-Peak Non-summer Base Rate All hours 5.4280ct per kWh APPLICATION , Page 8 Currently, the Time-of-Day "on-peak" rate is 8686q: per kWh, the "mid- peak" rate is 1717q: per kWh , and the "off-peak" rate is 3004q: per kWh. The proposed rates represent a 20 percent increase in "on-peak" rates , a 1 percent increase in "mid-peak" rates and a 15 percent decrease in "off-peak" rates. Customers participating in the Time-of-Day Pilot Program will continue to pay the monthly Service Charge of $3.30. TARIFFS Attachment No.1 to this Application is a copy of Idaho Power s proposed Schedule 4. Attachment No.2 to this Application is a copy of Idaho Power s proposed Schedule 5. Attachment No.3 to this Application includes copies of both Schedule 4 and Schedule 5 in legislative format. VI. MODIFIED PROCEDURE The Company believes that consideration by the Commission of the proposals contained in this Application does not require an evidentiary proceeding, and accordingly the Company requests that this Application be processed under RP 201 allowing for consideration of issues under modified procedure, i.e., by written submissions rather than by an evidentiary hearing. VII. NOTICES Communications with reference to this Application should be sent to the following: APPLICATION, Page 9 Maggie Brilz Pricing Director Idaho Power Company P. O.
