Company seeks recovery of costs for investments in infrastructure and technology

SPOKANE, Wash., June 09, 2017 (GLOBE NEWSWIRE) -- Capital investments in infrastructure, system maintenance, and technology and increased power supply costs are the main drivers in Avista’s (NYSE:AVA) request filed today with the Idaho Public Utilities Commission (IPUC or Commission).

“Our customers expect their energy to be there when they need it, and so do we. To meet these expectations, we’re continually investing in our systems in an effort to maintain reliability and deliver value, at a reasonable cost for customers,” Avista Chairman, President and Chief Executive Officer Scott L. Morris said.

These investments include the rehabilitation and maintenance of generating plants and distribution and transmission infrastructure that is necessary to serve customers. The work to upgrade and modernize this equipment will enable it to run efficiently and serve our communities for decades to come, said Morris. Avista’s rates are cost-based, where the costs related to projects that are included in customer rates reflects the cost of the equipment when it was installed, decades ago. As the company replaces the turbines, generators, poles and other equipment, the costs are many times more expensive today. This is a primary reason for the request to increase rates, he added.

“We understand that increasing prices can be a challenge. This is a key consideration as we make decisions about how and where to invest,” Morris said.

Two-Year Rate Plan
The proposal is a two-year rate plan for calendar years 2018 and 2019, with new rates taking effect Jan. 1, 2018 and Jan. 1, 2019. This plan would create a stay-out period where Avista would not file a new general rate case for a new rate plan to be effective prior to Jan. 1, 2020. This would provide customers with some predictability in their expected future energy prices.

Avista’s Requests
Avista’s request, if approved, is designed to increase annual electric billed revenues by $18.6 million or 7.9 percent, effective Jan. 1, 2018 and $9.9 million or 4.2 percent effective Jan. 1, 2019.

For natural gas, the rate request is designed to increase annual billed revenues by $3.5 million or 5.7 percent, effective Jan. 1, 2018 and $2.1 million or 3.3 percent effective Jan. 1, 2019.

The electric and natural gas requests for the January 2018-December 2019 rate periods are based on a proposed rate of return (ROR) on rate base of 7.81 percent with a common equity ratio of 50 percent and a 9.9 percent return on equity (ROE).

The company is not proposing to update base power supply costs for year two of the rate plan, but rather have any differences flow through the Power Cost Adjustment (PCA) mechanism.

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

Capital Investments
Avista’s capital investment plans address the need to replace infrastructure that has reached the end of its useful life, as well as respond to the need for reliability and technology investments required to build the integrated energy services grid for today and into the future.

Among the capital investments in today’s filing are:

• Generator rehabilitation at the Kettle Falls biomass plant that will ensure efficient generation and operations.
• The ongoing project to systematically replace portions of natural gas distribution pipe in Avista’s service area that were installed prior to 1987 as well as replacement of other natural gas service equipment.
• Transmission and distribution system investment, such as wood pole replacements, feeder upgrades, and substation and transmission line rebuilds to maintain reliability for our customers.
• Technology upgrades that support necessary business processes and operational efficiencies that allow Avista to effectively manage the utility and serve customers.
• A refresh of the customer-facing website, providing relevant information, greater accessibility on mobile devices, easier navigation, and a streamlined payment experience.

New and Expiring Rebates
As a result of the 2015 general rate case, customers are currently receiving a rebate of approximately $2.7 million for 2017 that expires on Dec. 31, 2017. In this filing, Avista has proposed to replace approximately one half of the current rebate in 2018 with $1.5 million related to the 2015 earnings sharing. The net effect of the new and expiring rebate for 2018 is a billed increase of approximately $1.2 million.
