                                                          June 5, 2002

                          AVISTA RESPONDS TO FERC ORDER
              AVISTA UTILITIES CONTINUES THOROUGH INVESTIGATION AND
                      PLEDGES TO COOPERATE FULLY WITH FERC

SPOKANE, WASH.: Avista Corp. (NYSE:AVA), in its continuing efforts to fully
cooperate with the Federal Energy Regulatory Commission (FERC), is in the
process of investigating in detail certain trades that are now being questioned
by FERC. The FERC order does not apply to Avista Energy, the energy trading and
marketing subsidiary of Avista Corp.

        "We have not knowingly withheld any information about Avista Utilities'
activities related to FERC's request," said Gary G. Ely, chairman, chief
executive officer and president of Avista Corp. "We will continue to do
everything possible to cooperate with FERC in this process to provide a complete
and accurate response."

        The trades in question were conducted on 18 trading days during a
three-month period between April and June 2000. The total number of megawatts
traded was limited to less than one-tenth of 1 percent of Avista Utilities'
trading activity during the period. The company earned less than $2,500 from the
transactions.

        FERC has ordered Avista to show why it should not have its market-based
trading authority revoked for the utility. Previously, Avista conducted searches
of its records, and the data was provided to FERC on May 22.

        As noted in its response to FERC, the time frame available did not allow
for detailed review of all transactions relevant to the data request. Avista is
now reviewing hundreds of hours of recorded conversations from trading
activities during the period in question.
