Avista files multiyear electric and natural gas rate plan in Idaho

SPOKANE, Wash., Feb. 01, 2023 (GLOBE NEWSWIRE) -- Today, Avista (NYSE: AVA) has filed a multiyear rate plan with the Idaho Public Utilities Commission that would allow the Company to recover costs for fixed expenses and ongoing investments to infrastructure, technology and more. If approved, new rates would be effective in Sept. 2023 and Sept. 2024.

“As an energy provider, we understand we play a vital role in the daily lives of those we serve, and we take this responsibility seriously,” said Avista president and CEO Dennis Vermillion. “As costs for goods and services have gone up across the board, we recognize how challenging increases in energy prices can be for our customers. We work hard to make decisions that will help keep these costs affordable, because we know this matters to all of our customers.”

“Part of the responsibility of providing an essential service is to make sure customers have energy when they need it. This means that we must continue to make important and necessary investments to the infrastructure that serves our customers such as replacing wood distribution poles and aging natural gas pipelines, making our system more resilient to the threat of wildfires and storms, upgrading customer-facing technology and substations, and much more. We’ve made these investments on behalf of our customers because it’s the right thing to do.

“There are also new pressures causing costs to go up for all companies and industries. Supply chain constraints, inflation and increasing interest rates are contributing to a challenging operating environment, making it more difficult to control costs. In just the last year, we’ve seen the costs of basic utility equipment such as transformers and electric poles increase in the range of 15-54%. Avista is not unique in this regard.

“We continue to aggressively manage costs to achieve the appropriate balance of providing safe and reliable service at cost-effective rates, along with a high level of customer satisfaction, while preserving the financial health of the utility. We are focused on long-term sustainable savings to continuously improve our service to customers and manage costs into the future.

“The ongoing effort to align the rates customers pay with Avista’s costs to serve is one of the main reasons we file general rate requests. It’s important for the health of the company and an essential part of providing safe and reliable energy.” Vermillion said.

Avista’s Requests

The proposal is a two-year rate plan, with new rates taking effect in Sept. 2023 and Sept. 2024. This plan would create a stay out period where Avista would not file a new general rate case for new rates to be effective prior to Sept. 2024. This would provide customers with some predictability in their expected future energy prices.

If approved, the electric general rate request is designed to increase annual base revenues by $37.5 million (or 14.7% on a billed basis) effective in Sept. 1, 2023, and $13.2 million (or 4.5% on a billed basis) effective in Sept. 1, 2024.

If approved, the natural gas general rate request is designed to increase annual revenues by $2.8 million (or 2.7% on a billed basis) effective in Sept. 1, 2023, and $0.1 million (or 0.1% on a billed basis) effective in Sept. 1, 2024.

The electric and natural gas requests are based on a proposed rate of return of 7.59%, with a common equity ratio of 50%, and a 10.25% return on equity.

Infrastructure Investments

Avista needs to continue 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 that will take us into the future. Among the projects included in today’s filing are:

• Ongoing management, inspection and replacement of 240,000 electric distribution wood poles through Avista’s wood pole management program to ensure poles and the equipment on them support the company’s ability to provide customers with safe and reliable power.
• Continued investment in Avista’s Wildfire Resiliency Plan, which outlines substantial steps that Avista has taken to guard against the growing threat of wildfires including grid hardening, enhanced vegetation management, and other industry-leading best practice measures.
• 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 to strengthen the integrity, safety, and reliability of the system.
• Technology upgrades that support necessary business processes and operational efficiencies that allow Avista to effectively manage the utility and serve customers.
