Modifications to Schedule 45, Standby Service
Dear Ms. Hanian:
Pursuant to RP 134.01 (IDAPA 31 .01 .01 .134.01), ldaho Power Company ('ldaho Power"
or'Compan/) seeks ldaho Public Utilities Commission approval of modifications to Schedule
45, Standby Service ("Schedule 45" or "Standby Service'). The Company is requesting to revise
Schedule 45 to expand the availability of Standby Service to Schedule g, l-arge General Service
Secondary Service level ('9S') customers.
Schedule 45 is cunently available to customers tiaking Primary or Transmission leve!
service under Schedule 9, Large General Service ('9P/T customers") or Schedule 19, Large
Power Service ("19PlT customers') who utilize on-site generation and who request Standby
Service from the Company. Recently, the Company has received interest from 95 customers
looking to install on-site generation. Expanding the availability of Schedule 45 to gS customers
would provide those 95 customers with on-site generation an offering to receive Standby
Service from the Company.
To determine the proposed Standby Service rates for gS customerc, the Company used
the same methodology that was used to compute the Standby Service rates applicable to 19Pff
customers (approved in the most recent general rate case, Case No. IPC-E-11-08). This is also
the same methodology that was used to compute the Standby Service rates applicable to 9Pff
customers when the Company requested to expand the eligibility of Schedule 45 to those
customers through Tarffi Advice No. 1G06 filed in November 2016. Using the most recently
filed cost-of-service study and conesponding unit cost sheets, the Company then made an
adjustment to reflect the inclusion of the Langley Gulch power plant in base rates; effective July
1, 2012, al! base rates were increased as a result of the inclusion of the Langley Gulch power
plant with an overa!! base revenue increase of 7.05 percent (Order No. 32585).
Finally, ldaho Power adjusted the billing units on the unit cost sheet to account for the
difference in the rate design applicable to 95 customers. Because the portion of the demand-
related costs for this customer class associated with a custome/s first 20 kilowatts of demand
is collected through the first tier of the energy rate, the billing units for demand on the unit cost

sheet must be adjusted to conectly align the billing units with the revenue requirement for the
purposes of calculating the Standby Service rates. Absent the adjustment, the 95 rates would
be understated due to the overstiatement of billing determinants. Attached is the calculation of
the proposed Standby Service rates for Schedule 9 Customers including all data used to
determine the rates.
ldaho Power respectfully requests that the modified Schedule 45 become effective July
15,2019. Also transmitted is a copy of Schedule 45 in both final and legislative formats.

Anderson at 388-6498.
