Rates increase slightly under PacifiCorp settlement

The Idaho Public Utilities Commission has approved a negotiated settlement
that increases rates for customers of PacifiCorp (Rocky Mountain Power in
eastern Idaho) by 0.77 percent effective Jan. 1, 2014. The agreement also
provides for no further increases in base rates until Jan. 1, 2016, at the
earliest.

For a residential customer who uses the company average of 830 kilowatt-
hours per month, the increase is less than $1 per month, according to the
company’s calculations.

“The commission believes that the value of a small, less than 1 percent
uniform increase for all rate classes over a two-year period and the
company’s agreement to not file another general rate case until May 31,
2015, provides significant value for customers,” the commission said. “In
particular, it ensures multi-year rate stability and is in the public interest.”

A commission staff review of the company’s application, which included an
expansive audit of the Company’s Results of Operations, revealed that the
company was prepared to file a rate case with a requested revenue
requirement of greater than $15 million. The settlement allows an additional
revenue requirement of $2 million, which is the remaining expense for the
Populus to Terminal transmission line already approved by the commission in
a previous rate case.

The settlement further allows PacifiCorp to defer up to $5.43 million in
expense associated with the new Lake Side II natural gas power plant south
of Salt Lake City. The plant begins serving customers next summer and
collection of costs related to the plant will be collected through the annual
Energy Cost Adjustment Mechanism (ECAM) beginning in 2015 and then
included in base rates after the next rate case. The ECAM, which can be an
increase or decrease depending on other factors, is adjusted every April 1.

The settlement also:

 Allows PacifiCorp to defer any net increase or decrease in depreciation
expense allocated to Idaho until after the next rate case. A settlement
to that case is currently before the commission (Case No. PAC-E-13-
02).
 Creates a regulatory asset for future recovery from customers of the
expense allocated to Idaho for removal costs related to the retirement
of the 172-megawatt Carbon coal plant near Helper, Utah.
 Accepts a new electric service agreement between PacifiCorp and its
largest customer, the Monsanto phosphate plant near Soda Springs,
which begins Jan. 1. 2014, with an initial term through Dec. 31, 2015.
The agreement includes a new section that allows for an annual true-
up of the credit Monsanto is allowed for agreeing to have its service
interrupted to provide additional electrical load to PacifiCorp. There
are still issues regarding the value of that interruption to PacifiCorp
that the parties will continue to negotiate. The commission
commended the parties on their efforts to reach agreement, but
reserved approval on the merits of the agreement until it is presented
under a separate docket.
