Section 8 – Other Events

Item 8.01 Other Events.

On February 9, 2015, Avista Corporation (Avista Corp.) filed electric and natural gas general rates cases with the Washington Utilities and Transportation Commission (UTC).

Avista Corp. has requested an overall increase in base electric rates of 6.6 percent (designed to increase annual electric revenues by $33.2 million) and an overall increase in base natural gas rates of 7.0 percent (designed to increase annual natural gas revenues by $12.0 million). Avista Corp.'s requests are based on a proposed rate of return on rate base of 7.46 percent with a common equity ratio of 48 percent and a 9.9 percent return on equity.

The major driver of these general rate case requests is to recover the costs associated with the ongoing need to maintain, replace and invest in Avista Corp.'s facilities and equipment. Several significant capital investments Avista Corp. has made and is currently making that are included in the filing are:

• the ongoing and multi-year redevelopment of the Little Falls Powerhouse on the Spokane River,

• the continuing rehabilitation of the Nine Mile Powerhouse on the Spokane River,

• information technology upgrades that include the replacement of Avista Corp.'s customer information and work management systems (which were implemented in February 2015),

• the ongoing project to systematically replace portions of Aldyl-A natural gas distribution pipe, and

• technology investments for deploying Advanced Metering Infrastructure in Washington, including installation of advanced meters, beginning in 2016.

The UTC has up to 11 months to review the filings and issue a decision.
