Avista affirms earnings guidance, reports weather data


SPOKANE, Wash., Jan. 20, 2003 — Despite warmer-than-normal temperatures and below-normal snowpack conditions, Avista Corp. reaffirmed its 2002 consolidated corporate earnings outlook of between $0.60 to $0.70 per diluted share and its 2003 consolidated corporate earnings outlook of between $0.80 to $1.00 per diluted share.

Both guidance ranges reflect corporate earnings before the effects of cumulative changes in accounting principles.

With dryer-than-normal weather impacting the region’s seasonal outlook, Avista is reporting preliminary snowpack for the Clark Fork River basin at 60 percent of normal, with projected runoff at 66 percent of normal. Approximately 80 percent of company-owned hydro generation is on the Clark Fork River.

The Spokane River snowpack is 65 percent of normal and projected runoff is expected to be 68 percent of normal. These forecasts assume a trend toward normal precipitation through April 1, when the current snow accumulation season ends.

Under the energy recovery mechanism (ERM) in Washington established in 2002, Avista Utilities absorbs the expense or receives the benefit from the first $9 million of power costs that differ from those in base rates for the calendar year 2003. During the first quarter of 2003, Avista Utilities expects to absorb the entire $9 million, which has already been factored into the company’s outlook and is due primarily to higher fuel costs. For the balance of 2003, 90 percent of any increased power costs will be deferred for future recovery.
