COMES NOW, ldaho Power Company ("ldaho Power" or "Company") and
supplements its response to the First Production Request of the Commission Staff to
ldaho Power Company dated November 21,2018, as follows:
IDAHO POWER COMPANY'S SUPPLEMENTAL RESPONSE TO
THE FIRST PRODUCTION REQUEST OF THE COMMISSION STAFF - 1
REQUEST NO. 1: ln Order No. 34046, the Commission ordered "an ldaho
Power specific on-site generation docket to study the costs and benefits of net metering
on ldaho Power's system, proper rates and rate design, alongside the related issues of
compensation for net excess energy." See Order No. 34046 a|22. Please provide all
relevant studies and reports conducted by the Company or on its behalf within the last 3
years.
SUPPLEMENTAL RESPONSE TO REQUEST NO. 1: In preparation of its
response to Vote Solar's First Production Request in Case No. IPC-E-18-15, ldaho
Power discovered a portion of the original load research data utilized to develop the
preliminary class cost-of-service study provided in the Company's response to Staffs
Request No. 1 in Case Nos. IPC-E-18-15 and IPC-E-18-16 did not conform to the
methodology described in the accompanying Attachment 4 to the initial response.
Specifically, the 2017 normalized load research data utilized to prepare the cost-of-
service study did not include the adjustment to remove the impact of demand response
programs as described in Attachment 4.
Additionally, in its review, the Company determined that the class data initially
relied upon for Schedule 6 and 8 customers included all months of service, which
encompasses the first partial month of service if applicable. To be consistent with the
Company's established load research sampling methodology, data collection should
only begin during the first complete calendar month of service under the rate schedule.
This effort ensures consistent treatment of customer classes for the derivation of
system-coincident and group-coincident demands.
IDAHO POWER COMPANY'S SUPPLEMENTAL RESPONSE TO
THE FIRST PRODUCTION REQUEST OF THE COMMISSION STAFF - 2
The Company is providing all impacted workpapers that have been updated from
the preliminary class cost-of-service study with this supplemental response.
The response to this Request is sponsored by Connie Aschenbrenner, Rate
Design Senior Manager, ldaho Power Company, and Matt Larkin, Revenue
Requirement Senior Manager, ldaho Power Company.
DATED at Boise, ldaho, this 29th day of March 2019.
