Washington Okays Avista Cost Recovery Plan

LCG, May 25, 2001--The Washington Utilities and Transportation Commission has approved an unopposed settlement agreement reached last month between Avista Corp., the staff of the WUTC, the Public Counsel Section of the Washington Attorney General's Office and the Industrial Customers of Northwest Utilities.

Under the agreement, Avista will be able to extend to February 2003 a deferred accounting method that will allow it to weather a period of power shortages without increasing rates to its customers, the company said this morning.

Avista said it expects to be in a surplus power position next year and the revenues from surplus power sales are expected to offset power costs the company has been incurring since July of last year. The company said it anticipates reducing the power-cost deferral balance to zero by the end of February 2003.

In its order, the commission said "Our approval of the Settlement Stipulation offers significant potential that Avista will not seek any increase in rates to its customers related to power supply costs despite the volatility of wholesale power markets in our region during recent periods."

Gary G. Ely, Avista's chief executive, said his company has "worked extremely hard to shield our customers from the substantial electric rate increases that others throughout the region are already experiencing."
