AVISTA CORP. INCURS SIGNIFICANT INCREASES IN ENERGY EXPENSES
DUE TO SUSTAINED PEAKS IN PURCHASED-POWER COSTS
Q2 EARNINGS EXPECTED TO BE BREAKEVEN
VALUE CREATION STRATEGIES REMAIN ON TRACK

SPOKANE, WASH.: Avista Corp. (NYSE: AVA) today announced that unprecedented
sustained peaks in electric energy prices throughout the Pacific Northwest and
California in May and June, compounded by a wholesale short position exceeding
management guidelines, are contributing to significant losses for the second
quarter at the company's regulated utility operation.

    Avista Utilities is expected to spend approximately 25 percent more for
purchased power this year because of sustained price peaks, causing it to lose
more than $90 million in gross margin in the second quarter due to additional
power costs. If current pricing levels sustain through year-end, additional
potential losses of at least $50 million in gross margin could occur.

    The company's unregulated Avista Energy unit is expected to earn an
estimated $70 million or more in gross margin in the second quarter, reflecting
current results as well as the mark-to-market value of its contracts. Based on
current projections, Avista Corp. expects to post breakeven results for the
second quarter and for the full year, before preferred dividends. This
performance reflects Avista Energy's positive results and the gain on the May 4
sale of its minority interest in a coal-fired generating unit in Centralia,
Wash.

    The utility's short position was compounded by the sale of the Centralia
plant, which reduced its system capacity by 175 megawatts. Avista's interest in
this plant was sold because of the future high environmental mitigation costs
related to the plant. This transaction resulted in an estimated after-tax net
gain of $34 million of which approximately $26 million will be returned to
Avista Utilities' customers and the remaining $8 million net gain will be
reflected in Avista Corp.'s second quarter earnings. As part of the Centralia
sale, Avista Utilities entered into a favorably priced contract to purchase 175
megawatts from the Centralia plant beginning in July 2000. Because of lower
power pricing at the time of the sale and historical trends, Avista Utilities
did not seek to cover the months of May and June with firm commitments. In
hindsight, not covering this short position was a mistake.

    Avista Utilities President Edward Turner said, "We believe the electric
energy markets in the Northwest are fundamentally changing. Based on historical
trends, our Avista Utilities second-quarter business plan had forecast on-peak
power prices at $19 levels. In recent weeks, Avista's on-peak power costs
averaged $60 per megawatt in May and over $100 per megawatt in June, with spikes
as high as $750 per megawatt. Prices are at an unprecedented level, the likes of
which have never been seen in the Pacific Northwest, without any apparent
relationship to actual costs of generation." (Note: The attached "Mid-Columbia
Weekly On-Peak Prices" chart provides additional data points on power pricing.

    T. M. "Tom" Matthews, Avista Corp. chairman, president and chief executive
officer, said, "We are taking extensive measures to address our power cost
issues, minimize our risk and mitigate our utility's financial hardship. These
efforts include company-wide administrative expense reductions, cutbacks in
utility capital expenditures, the elimination of short-term wholesale commodity
sales within the utility not related to optimizing resources for its customers,
an aggressive review of alternatives for adding generation and an immediate
request for an accounting order permitting the utility to recover its
extraordinary power costs associated with utility retail operations."

    Avista's general rate case, which is pending before the Washington Utilities
and Transportation Commission (WUTC), includes a request to allow Avista
Utilities to implement an energy cost adjustment mechanism. This mechanism would
allow increases and decreases in energy costs to be passed through to customers
as incurred, without a general rate case, similar to Avista's power cost
adjustment mechanism in Idaho.

    Additionally, in recognition of the need for additional generation in the
Pacific Northwest, Matthews noted that the company's Avista Power unit recently
broke ground on a 250-megawatt plant in Idaho. Avista Power is in the final
stages of closing on a second 250-megawatt plant to be constructed next year in
Oregon. Both projects will be powered by efficient, combined-cycle natural gas
turbines.

        As discussed in Avista Corp.'s annual report on Form 10-K, the wholesale
electric business has been a secondary, but significant, part of Avista
Utilities' business strategy. The wholesale business has included marketing
capacity and energy under long-term contracts and trading energy on a short-term
basis. Avista Utilities will in the future eliminate all trading activity not
related to optimizing its resources.

        Consistent with previous years, during the second quarter Avista
Utilities made purchases of energy in order to satisfy its obligations to retail
and long-term wholesale customers, to the extent that the company's own
generating resources were not sufficient. Due to the spikes in power described
above, the price of these purchases was significantly higher than the levels of
purchased power expense recoverable from customers.

        In addition, an Avista Utilities energy trader entered into excessive
levels of short-term, fixed-price contracts for wholesale sales for delivery of
power through October 2000, without making matching purchases at the time.
Avista Utilities was forced to buy additional power at prices significantly
higher than the selling prices to cover those contracts.

        The volume of short-term wholesale sales exceeded management guidelines.
When senior management became aware of the short positions, it was determined,
in light of projected market conditions based on historical pricing data, that
the most prudent course of action was to avoid the high costs of immediate
action to offset the effect of these positions. Instead, the utility began to
gradually diminish its exposure. This process has been impeded by the continuing
high levels of market prices and lack of liquidity in the power markets.

        During the balance of the year, the demands on Avista Corp. cash
resources are expected to increase significantly. Additional cash needs include
increased purchased power expense, as well as calls for cash collateral by
Avista Energy's counterparties. Avista Corp. anticipates, based on information
currently available, that it will be able to satisfy all cash requirements.

        Matthews said, "We believe we are addressing all of the near-term issues
facing the utility and we remain confidently focused on Avista's strategies for
value creation and growth. We're continuing to create value with the growth of
our industry-leading Avista Advantage B2B e-commerce business and with the
development of our innovative Avista Labs PEM fuel cell subsidiary. We are in
the process of identifying the best timing for unlocking the value in these
businesses as well as our telecom business so we can maximize shareholder
value."

        Avista Corp. is an energy, information and technology company whose
utility and subsidiary operations focus on delivering superior products and
providing innovative solutions to business and residential customers throughout
North America.
