Avista Reaches Settlement in Idaho Electric and Natural Gas Rate
Requests
Temporary $17.5 milion credit would reduce bil impact to customers; annual power cost
adjustment surcharge also filed
SPOKANE, Wash. - July 26,2010,1:05 p.m. PDT: Avista (NYSE: AVA) and other parties
involved in the company's electric and natural gas rate filing have reached a settlement agreement
that, if approved by the Idaho Public Utilties Commission (IPUC), would result in an overall electric
increase of 9.3 percent and a 2.6 percent natural gas increase, effective Oct. 1, 2010. Partially
offsetting the increases, and lowering the bil impact to customers, wil be a $17.5 millon credit to
customers to return the balance of deferred Idaho state income taxes from prior years.
"We're pleased that this settlement agreement recognizes the need to recover costs to serve our
customers and that our customers will benefit from the return of state income taxes, which is an
important element in reducing the rate impact on them," said Dennis Vermillon, Avista Corp. senior
vice president and president of Avista Utilties. 'We believe the settlement agreement represents a
fair and reasonable outcome for our customers and shareholders."
Under the terms of the settlement agreement, electric revenues would increase by $21.25 millon,
or an overall 9.3 percent, and a revised level of power supply costs to be used in future Power
Cost Adjustment (PCA) calculations would be set. The revised power supply costs reflect a
reduction of approximately $7 millon from the costs included in the company's original revenue
increase filing of $32.1 millon. The agreement is the result of concessions made by the parties on
a number of issues to arrve at an outcome that is supported by the parties.
The $17 millon credit would offset electric prices for customers for two years, reducing the impact
of the electric rate increase effective Oct. 1, 2010, from an overall 9.3 percent to 3.59 percent. With
the offsetting credit, a residential customer using an average of 1,000 kilowatt-hours a month
would see a $3.50 per month increase, or 4.3 percent, for a revised monthly bil of $84.40.
Under the terms of the settlement agreement, electric rates would then increase 3.92 percent on
Oct. 1, 2011, and 1.74 percent on Oct. 1, 2012, after which the temporary credit would expire. The
return of deferred state income taxes to Avista's 122,000 electric and 74,000 natural gas
customers in Idaho would not affect net income for the company.
Natural gas revenues under terms of the settlement agreement would increase by $1.85 milion, or
2.6 percent. A credit of $500,000 would reduce for one year the natural gas rate increase to 1.9
percent, or $1.71, for a revised monthly bil of $59.40 for a customer using an average of 65 therms
a month. The rate change would also be effective Oct. 1, 2010.
To help customers better manage their energy bils, annual funding for the low-income
weatherization program would be increased to $700,000, up from the current $465,000. Support
for low-income energy effciency outreach and education would also increase from $25,000 to
$40,000. Community Action Program (CAP) agencies manage both the low-income weatherization
and energy effciency and education programs.
Power Cost Adjustment
Separately, Avista today filed its annual Power Cost Adjustment (PCA) which captures the
difference between Avista's actual cost of generating and purchasing power over the prior 12
months and the cost currently included in customer rates. The filing requests an overall 2.6 percent
increase .in electric rates with an Oct. 1, 2010, effective date.
The increased costs are driven primarily by below-normal hydroelectric generation for the first half
of 2010, due to snow pack levels that were well below normal, and the costs associated with the
addition of the Lancaster generating project beginning on January 1, 2010. The Lancaster power
supply costs were approved for recovery in the PCA until they are reflected in base retail rates.
The approval by the IPUC of both the settlement agreement, including the deferred state income
tax credit, and the PCA surcharge true-up would adjust the monthly electric bil for a residential
customer using an average 1,000 kilowatt-hours a month to $86.27, for a combined increase of
$5.37, or 6.6 percent.
