COMES NOW, ldaho Power Company ("ldaho Power" or "Comp?fly"), and
supplements its response to the ldaho Public Utilities Commission Staff's ("Staff')
Request No. 30 dated March 10,2017 , as follows:
IDAHO POWER COMPANY'S SUPPLEMENTAL RESPONSE
TO THE COMMISSION STAFF'S PRODUCTION REQUEST NO. 30 - 1
REQUEST NO. 30: Please quantify the dollar revenue requirement difference
between the Company's proposal to accelerate Valmy depreciation rates, and leaving
the currently-approved depreciation rates in place, i.e. no acceleration, regardless of the
actual retirement dates for Valmy 1 and Valmy 2 under each of the following scenarios:
a. lncluding full recovery of the forecasted capital additions and including
decommissioning costs, with Valmy 1 scheduled for retirement as currently planned in
2031 and Valmy 2 scheduled for retirement as currently planned in 2035.
b. Without including recovery of the forecasted capital additions but including
decommissioning costs, with Valmy retiring at2031as currently scheduled and Valmy 2
retiring at 2035 as currently scheduled.
SUPPLEMENTAL RESPONSE TO REQUEST NO. 30: As discussed in the
Company's initial response to Staffs Request No. 30 filed on March 24,2017,ldaho
Power committed to provide the requested analysis no later than Friday, March 31,
2017.
The requested analysis is provided as Attachments 1 through 4 on the enclosed
CD. Please note that because the requested analysis reflects different cost recovery
periods for Units 1 and 2, each scenario requires two workbooks: one to calculate the
annual levelized revenue requirement to recover Valmy Unit 1 costs by 2031 and one to
calculate the annual levelized revenue requirement to recover Valmy Unit 2 and
common costs by 2035. Each scenario reflects costs associated with the Company's
filed assumption of both Units 1 and 2 ceasing actual operations in 2025.
The response to this Request is sponsored by Randy Henderson, Finance Team
Leader ll, ldaho Power Company.
