STIBJECT: IDAHO POWER,S APPLICATION TO IMPLEMENT FD(ED COST
ADJUSTMENT RATES EFFECTTVE JrIh[E 1,2017, THROUGIT MAy 31,
2018, CASE NO. rPC-E-17-02
On March 15,2017,Idaho Power Company applied to the Commission for authority
to implement new Fixed Cost Adjushent (FCA) rates for electric service from June 1,2017,
through May 31, 2018. The Company asks the Commission to process the case by Modified
Procedure.
The FCA is a rate adjustment mechanism that separates the Company's ability to
recover its fixed costs from the revenues it derives from selling energy.l The FCA thus removes
the Company's financial disincentive to invest in energy efficiency resources and demand-side
management resources that might otherwise decrease its customers' energy use and,
consequently, the fixed costs it recovers by selling energy. Under the FCA, the Company credits
customers when it recovers less "actual fixed costs" than the base level of fixed costs that the
Commission authorized it to recover through rates during the last general rate case. On the other
hand, the Company charges customers an extra amount when its "actual fixed costs" exceed the
base level of fixed costs. The Company's FCA rates are specified in tariff Schedule 54 and
apply to the residential and small general service customer classes.
In this Application, the Company states that the difference between the authorized
recovery amount and the actual fixed costs recovered is$33,762,766 for the residential class and
lA utility's "fixed costs" are its costs to deliver energy that do not vary with energy use, output, or production and
remain relatively stable between general rate cases. They include costs associated with long-lasting infrastructure
(e.g., power plants, power lines, and substations), and certain administrative costs.
IDECISION MEMORANDUM
o o
$1,249,276 for the small general service class, for a total amount to be recovered through this
year's FCA of $35,012,042 (the FCA "deferral balance"). This year's proposed FCA deferral
balance is an increase from what is currently collected through rates. To recover this increase,
the Company proposes combined residential and small general service class increase of 1.29o/o.
The proposed rate increase equates to a monthly rate increase of about 0.67$, per kilowatt-hour
(k\Yh) for the residential class, and 0.861 per kWh for the small general service class. The
Company says that average residential customers using 1,050 kWh a month would see about a
$1.31 per month increase on their bills starting June 1, 2017.
