Section 8 – Other Events

 

Item 8.01 Other Events.

On August 31, 2006, Avista Corporation (Avista Corp. or the Company) filed a request with the Washington Utilities and Transportation Commission (WUTC) to increase electric rates for its Washington customers by an average of 8.8 percent, which is intended to increase annual revenues by $28.9 million. The proposed increase, referred to as a Production/Transmission Update (P/T Update) includes an update to those production and transmission costs that are included in base retail rates, and that are part of the Energy Recovery Mechanism (ERM). In Washington, the ERM allows Avista Corp. to increase or decrease electric rates periodically with WUTC approval to reflect changes in power supply costs. The ERM is an accounting method used to track certain differences between actual power supply costs and the amount included in base retail rates for Washington customers.

The Company is not requesting an increase in rates related to cost changes associated with administrative and general expenses, operation and maintenance expenses, or the cost of equity and capital structure. In this filing, however, Avista Corp. is proposing to flow through to customers the lower cost of debt the Company is experiencing since the last general rate case.

Included in the P/T Update are investments to upgrade several of the Company’s hydroelectric generating units to increase their efficiency and the continued upgrades to the Company’s 230-kilovolt high voltage transmission system to increase reliability and transmission capability to serve growing customer demand. Also contributing to the need for the P/T Update are higher operating costs for purchasing and generating electricity to serve Avista Corp.’s customers.

The filing proposes that new rates become effective on or before February 1, 2007.
