Avista Requests Electric Rate Increase in Idaho

Company Seeks Recovery of Costs for Investments in Infrastructure; Does Not Request Increase in Natural Gas Rates

SPOKANE, WA--(Marketwired - May 26, 2016) - Capital investments in infrastructure and system maintenance are the main drivers in Avista's (NYSE: AVA) electric request filed today with the Idaho Public Utilities Commission (IPUC or Commission).

Avista's request, if approved, is designed to increase annual electric revenues effective Jan. 1, 2017, by an overall 6.3 percent or $15.4 million.

The request is based on a proposed rate of return (ROR) on rate base of 7.78 percent with a common equity ratio of 50 percent and a 9.9 percent return on equity (ROE).

"Serving our customers with safe, reliable energy at a reasonable cost is our priority. We must continually invest in the facilities and systems we use to serve customers, including maintenance, replacements and upgrades, to meet their energy needs and expectations now and into the future. The costs of doing business and making these infrastructure investments continue to rise, and this is what is driving our general rate requests," Avista Chairman, President and Chief Executive Officer Scott L. Morris said.

Avista serves more than 128,200 electric customers in Idaho. The IPUC has up to nine months to review Avista's request.

Capital Investments
Capital investments included in Avista's request include upgrades and maintenance of the company's generation facilities, transmission and distribution equipment, and technology. Costs to replace facilities and parts of our system are many times more expensive today than when originally installed. This is the primary reason for the need to increase rates.

Among the major capital investments in today's filing are:

  • the ongoing and multi-year redevelopment of the 106-year-old Little Falls Powerhouse on the Spokane River to increase generation reliability and the continuing rehabilitation of the 108-year-old Nine Mile Powerhouse on the Spokane River, including the replacement of original generators, turbines and other equipment which will increase the generation of clean, renewable power;
  • the refurbishment of Post Falls South Channel Dam, built in 1906, with six new spill gates, frames and hoists along with a new spillway control system, electrical distribution and concrete facing that enable the structure to continue its role in generating clean, low-cost renewable energy.

Residential Customer Electric Bill
If Avista's electric request is approved, a residential customer using an average of 918 kilowatt hours per month could expect to see a bill increase of $6.54 per month, or 7.7 percent, for a revised monthly bill of $91.26. The bill change includes a proposed increase of $1.00 per month in the basic charge, from $5.25 to $6.25 per month.

The requested electric increase by service schedule is as follows:
Rate Schedule Proposed Billing Increase
Residential Service - Schedule 1 7.7 percent
General Service - Schedules 11 & 12 4.5 percent
Large General Service - Schedules 21 & 22 5.6 percent
Extra Large General Service - Schedule 25 4.7 percent
Extra Large General Service 25P - Schedule 25P 4.5 percent
Pumping Service - Schedules 31 & 32 7.5 percent
Street & Area Lights - Schedules 41 - 49 8.2 percent
Total 6.3 percent
