              AVISTA FILES GENERAL RATE CASE WITH IDAHO REGULATORS
         Company seeks approval of electric price increase of 11 percent
       above current rates and a natural gas price increase of 9.2 percent

SPOKANE, WASH.: Avista Corp. (NYSE:AVA) has filed a request with Idaho
regulators to increase electric prices by 11 percent above current rates and
natural gas prices by 9.2 percent. Avista's request is designed to increase
electric revenues by $18.9 million annually and natural gas revenues by $4.8
million annually. The Idaho Public Utilities Commission (IPUC) generally has up
to seven months to review Avista's rate case filing.

         Avista has not had a general electric price increase in Idaho since
1999, and this would be the first general natural gas price increase in Idaho
since 1990. Avista has invested $81 million in its electric generation and
transmission system, another $54 million in electric distribution, and $73
million in its natural gas system since its last general rate increases - a
total of more than $200 million of additional utility plant to meet the needs of
its customers.

         In addition, Avista's current rates in Idaho are based on the company's
1997 operating costs on the electric side of its business and 1987 operating
costs on the natural gas side. Accordingly, existing rates do not reflect
Avista's current costs of providing electric and natural gas service to its
customers.

         Under the company's proposal, the monthly bill for a residential
electric customer with average monthly usage of 1,000 kilowatt-hours of
electricity would increase from $60.15 to $68.37, an increase of $8.22 per
month. The monthly bill for a residential gas customer using an average of 70
therms of natural gas would increase from $57.68 to $63.26, an increase of $5.58
per month. Avista is proposing that the basic monthly charge for residential
electric service be increased from $4.00 to $5.00 and the natural gas basic
monthly charge be increased from $3.28 to $5.00.

         On the electric side, the request will be for a 24 percent overall
change in base rates. However, Avista is requesting a reduction in its current
Power Cost Adjustment surcharge, which would reduce the overall impact on
customers to an 11 percent increase above current rates. In 2001, the IPUC
approved a 19.4 percent surcharge that allowed Avista to begin recovering costs
associated with the record-low streamflow conditions and high market prices
incurred by the company during the energy crisis of 2000 and 2001. If the
commission approves Avista's proposal, the remaining PCA balance would be
recovered over a two-year period at a reduced rate.

         "Our filing reflects the company's efforts to ensure long-term and
reliable energy supplies for our customers. To accomplish that goal, we've made
significant investments in new generating resources and in electric and natural
gas infrastructure since our last general rate case filings," said Scott Morris,
president of Avista Utilities. "We have been quite purposeful in successfully
meeting our objective of owning or controlling electric resources exceeding 100
percent of our retail load. Our focus has been on controlling our own destiny
and reducing reliance on potentially volatile energy markets."

         Morris also noted that the rate request represents another step in the
company's financial recovery and its ongoing efforts to restore its investment
grade credit rating, which was lowered during the 2000-01 energy crisis.

          Among the issues Avista is asking the commission to consider in its
electric and natural gas rate filings are the company's investment in the Coyote
Springs 2 generating station, operation and maintenance costs, increased power
supply costs, and increased financing costs since the company's last electric
and natural gas general rate cases.

         Avista recognizes the impact of price increases on its customers,
especially on those who have the most difficulty paying their energy bill.
Avista's ongoing commitment to customers also includes support of Project Share,
an energy assistance program. Other customer programs include CARES, a program
assisting those who face challenges paying their bills; Comfort Level Billing, a
plan that averages annual energy bills into equal monthly payments; and ongoing
energy conservation and efficiency programs.

         Avista also offers rebates for residential weatherization (wall, floor,
ceiling, ducts) and high efficiency water heaters and furnaces. The company
offers energy conservation education, including workshops for seniors, energy
use guides and home visits by meter shop personnel to help customers reduce
energy costs on a long-term basis.

         Approximately 30 percent of the company's annual retail electric and
natural gas revenues are derived from Idaho where the company serves 109,000
electric customers and 62,000 natural gas customers. Avista has added 8,275
electric customers and 9,040 natural gas customers in Idaho in the past five
years.
