Item 5. Other Events and Regulation FD Disclosure

On February 6, 2004, Avista Corporation (Avista Corp.) filed a request with the Idaho Public Utilities Commission (IPUC) to change its electric and natural gas rates. A copy of Avista Corp.’s press release is filed as Exhibit 99(a).

Avista Corp.’s request is designed to produce a net increase in electric revenues of 11 percent, or $18.9 million in annual revenues, over current rates. This would result from a 24 percent increase in base retail rates (an increase of $35.2 million in annual revenues) offset by a decrease in the current Power Cost Adjustment (PCA) surcharge of $16.3 million in annual revenues. The current PCA surcharge is approximately 19 percent of base retail rates.

Avista Corp. has requested a natural gas general rate increase of 9.2 percent, or $4.8 million in annual revenues.

Avista Corp.’s request is based on an overall rate of return of 9.82 percent and a return on equity of 11.5 percent. The IPUC generally has up to seven months to review the general rate case filing.

Neither the filing of any press release as an exhibit to this Current Report nor the inclusion in such press releases of a reference to the Internet address of Avista Corp. or Avista Utilities shall, under any circumstances, be deemed to incorporate the information available at such Internet addresses into this Current Report. The information available at the Internet address of Avista Corp. or Avista Utilities is not part of this Current Report or any other report furnished or filed by Avista Corp. with the Securities and Exchange Commission.
