Avista Requests Electric and Natural Gas Rate Increase in Washington

SPOKANE, WA--(Marketwired - Feb 4, 2014) - Increased capital investments is the major driver in Avista's (NYSE: AVA) request filed today with the Washington Utilities and Transportation Commission (UTC) to increase electric and natural gas base rates. Avista has requested an effective date of Jan. 1, 2015. The last general rate request filing in Washington was April 2, 2012.

"The majority of the company's rate request comes from the continuing need to expand and replace the facilities and equipment we use every day to serve our customers," Avista Chairman, President and Chief Executive Officer Scott L. Morris said. "This includes preserving the life of our legacy hydropower projects that have been providing low-cost, renewable energy for over 100 years. It also includes continuing to systematically replace some of our older energy delivery facilities every year, so that our customers will continue to receive safe, reliable service in the years to come. The cost to replace these facilities is multiple times more expensive than the original cost to install them, which results in a need to increase rates.

"Managing costs is an on-going focus for Avista which helps ensure that our customers continue to have among the lowest energy prices in the country. To help reduce the rate of growth in operating costs, Avista implemented in December 2012 a Voluntary Severance Incentive Plan to reduce the number of employees at the company beginning Jan. 1, 2013. Effective Jan. 1, 2014, Avista also made changes to its pension and post-retirement medical plans for non-union employees that reduce future costs," Morris said.

Avista's request, if approved, would increase annual electric base revenues by 3.8 percent or $18.2 million and annual natural gas base revenues by 8.1 percent or $12.1 million. Both requests are based on a proposed rate of return on rate base of 7.71 percent with a common equity ratio of 49.0 percent and a 10.1 percent return on equity.

In addition, Avista's electric customers are receiving benefits from two rebates that are currently reducing customers' monthly energy bills by 2.8 percent during 2014. These rebates will expire at the end of 2014. Avista is proposing a new rebate beginning January 1, 2015, related to its sale of renewable energy credits which would reduce customers' monthly bills by 1.1 percent. The net effect of the expiring rebates and the new rebate will result in an increase of approximately 1.7 percent beginning January 1, 2015. These rebates are passed through to customers on a dollar-for-dollar basis and do not increase or decrease the company's earnings.

If Avista's requests are approved, a residential customer using an average 965 kilowatt hours per month would see a total billed increase of $4.89 a month, or 6.1 percent, for a revised monthly bill of $84.98, beginning January 1, 2015. The revised monthly bill includes a proposed increase in the monthly basic charge from $8.00 to $15.00.

A natural gas customer using an average of 65 therms per month would see a $5.23, or 8.5 percent, increase for a revised monthly bill of $66.42. This includes the proposed increase in the monthly basic charge from $8.00 to $12.00.

Avista serves more than 241,000 electric and nearly 152,000 natural gas customers in Washington.

Capital investments
Avista expects capital investments in 2014 of $335 million, up from $280 million in 2013. The investments encompass upgrades and maintenance of generation facilities, transmission and distribution equipment, natural gas pipe, as well as information technology upgrades.

Among the major capital investments in today's filing are portions of the multi-year redevelopment of the 104-year-old Little Falls Powerhouse to increase generation reliability; continuing rehabilitation of the 106-year-old Nine Mile Powerhouse to replace original generators, turbines and other equipment which will increase the generation of clean, renewable, low-cost power; and the 2014 restoration of the 106-year-old Post Falls South Channel Dam structure to preserve the life of this important generating resource.

Information technology upgrades include the replacement of Avista's 20-year-old legacy customer information system which supports traditional utility business functions, such as meter reading, customer billing, payment processing, credit, customer service orders and material management.

Natural gas capital investments include the continuing project to systematically replace portions of natural gas distribution pipe. The project is replacing hundreds of miles of natural gas distribution lines in Avista's Washington, Idaho and Oregon service area that were installed prior to 1987.
