Commission begins
processing Avista rate case
The
Idaho Public Utilities Commission has suspended for up to six months a request
by Avista Utilities to increase its electric rates by 14 percent and natural
gas rates by 3.6 percent. The company seeks to increase its annual revenue by
$32.1 million and is asking for an overall rate of return of 8.55 percent and a
return on equity of 10.9 percent.
The
suspension is routine procedure for the commission in major rate cases to allow
the commission’s staff of auditors, engineers and attorneys time to thoroughly
investigate Avista’s application.
If
the increases were granted in full, the bill of an average residential electric
customer (964 kilowatt-hours per month) would increase by $11.40. The gas
increase would be about $2.77 per month for a residential customer who uses 63 therms per month.
State
law requires that regulated utilities be allowed to recover their prudently
incurred expenses and earn a reasonable rate of return, which is also
established by the commission. When the commission denies recovery of some or
all expenses, it must be able to legally demonstrate
why the expense was not needed to serve customers or was not prudently
incurred. Commission rulings can be appealed to the state Supreme Court by
either the utility or customer groups.
Organizations
representing customer groups have until April 23 to file for intervention
status in the case. Those granted intervention may present evidence,
cross-examine witnesses and participate in settlement conferences.
Organizations that have filed to intervene thus far include Idaho Forest
Products, Clearwater Paper Company and the Idaho Community Action Network, the
latter representing low-income customers. Avista customers not representing
customer groups will also be able to participate in the case by filing written
comments and attending public workshops and testifying at formal hearings to be
announced at a later date.
Avista
claims the increases are necessary because of escalating power supply costs,
increased costs to meet new federal requirements that ensure reliability, and
the need to replace aging infrastructure.
Power
supply contracts that provide Avista customers with about 100 average
megawatts, about 10 percent of the company’s entire retail load, expire at the
end of this year. The power provided by these contracts is about 3 cents per
kilowatt-hour, which is well below the cost to replace that power, according to
Avista president and CEO Scott Morris. Avista’s average cost of resources is
now about 4.3 cents per kWh. The additional cost to replace the expiring
contacts will be about $10 million, according to Avista.
Also
included in this case are about $21 million in costs related to a power
purchase agreement with the owners of the Lancaster natural gas generating
station near Rathdrum. About 80 percent of Avista’s requested increase is
attributable to the Lancaster agreement, termination of the low-cost power
contracts and increased customer load.
Replacing
aging infrastructure has also resulted in increased costs to the company, Morris
said. For example, the cost of a transformer that steps down voltage to
residential customers has increased to more than $1,400 per transformer. Six
years ago the cost was about $750 per transformer. A transformer is needed to
serve every three to four residential or small-business customers. About 12
percent of the requested increase is attributable to upgrades of existing
infrastructure.
Avista’s last rate
case, filed in early 2009, resulted in an average 5.7 percent base rate
increase to customers last July after the company requested 12.8 percent in
January. However, customers ended up paying 1.5 percent more, after a 4.2
percent reduction in the annual Power Cost Adjustment (PCA) was applied against
the base rate increase.
Base gas rates
increased by 2.1 percent last year. However, the base rate increase was more
than offset by three reductions in the Purchase Gas Cost Adjustment (PGA)
portion of customer bills due to the declining prices of natural gas on the
wholesale market. Those reductions were 4.7 percent in January, 6.7 percent in
June and 22 percent in November. With the PGA reductions, the average
residential natural gas bill is now $61.82 per month compared to $83.94 per
month at the beginning of 2009.

Case Numbers AVU-E-10-01 or AVU-G-10-01. Avista’s application and testimony
from its officers is now on the site. As the case progresses, more testimony,
including that from other parties in the case and commission staff, will be
added.
