Avista requests recovery of costs for providing service in Oregon

Investments in infrastructure and reliability drive rate request

SPOKANE, Wash., March 15, 2019 (GLOBE NEWSWIRE) -- Continuing capital investments in natural gas infrastructure led Avista (NYSE: AVA) to file a request today with the Public Utility Commission of Oregon (PUC) to increase natural gas base rates.

The proposal is designed to increase overall natural gas billed revenue by approximately $6.7 million or 7.8 percent and is based on a proposed rate of return of 7.55 percent with a common equity ratio of 50 percent and a 9.9 percent return on equity.

"This general rate request is driven by investments in our natural gas infrastructure that serves our customers in Oregon,” said Dennis Vermillion, president of Avista. “We continuously invest in the natural gas system, and this request includes projects that support the safe, reliable delivery of natural gas to our customers as well as the replacement of old equipment, compliance with government regulations and requirements, technology upgrades and more. While customers have benefitted from low natural gas commodity prices, we understand that this requested increase can be challenging, and we are focused on managing our costs, maximizing efficiencies and delivering value for our customers.”

The last general rate request Avista filed in Oregon was Nov. 30, 2016, with new base rates that took effect on Oct. 1, 2017 and Nov. 1, 2017. This request is separate from the Purchased Gas Cost Adjustment (PGA) and other annual rate adjustment filings that took effect on Nov. 1, 2018, lowering an average customer bill by 8.3 percent or $4.56 per month.

Capital Investments
The majority of the current capital investments include upgrades and maintenance of natural gas pipe and distribution equipment as well as other information technology upgrades. Major capital investments included in today's filing are:

  • The continuation of a major project to replace portions of natural gas distribution pipe. The project is replacing hundreds of miles of natural gas pipeline that was installed prior to 1987.
  • Expansion of the natural gas system to meet the growing needs of customers.
  • Replacement of natural gas pipe to improve the operation of the natural gas system and accommodate development and construction projects.
  • Implementation and upgrades of technology systems that make it easier for customers to do business with Avista and that allow employees to perform their jobs and serve customers in a safe, reliable and efficient manner.

Customer Bills
If the general rate request is approved by the PUC, a residential customer using an average of 47 therms per month would see a $3.91 per month increase, or 8.0 percent, for a revised monthly bill of $52.85. The revised monthly bill includes a proposed increase in the monthly basic charge from $10.00 to $12.00.

On average, about 35 percent of an Avista bill for Oregon residential customers is the combined costs of purchasing natural gas on the wholesale market and transporting it to our system for delivery to customers. The remaining 65 percent is related to the ownership and operating costs of Avista's delivery system to provide safe, reliable service to all customers, while meeting mandatory state and federal requirements.

Avista serves approximately 103,000 customers in Oregon. The PUC has up to 10 months to review Avista's request.
