**Section 8 - Other Events**

**<u>Item 8.01 Other Events.</u>**

On March 1, 2023, Avista Corporation filed a natural gas general rate case with the Public Utility Commission of Oregon (OPUC). If approved, new rates would be effective on January 1, 2024.

The proposed rates are designed to increase annual base natural gas revenues by $11.0 million (or 14.4 percent).

The proposed revenue increase request is based on a proposed rate of return of 7.59 percent, with a common equity ratio of 50 percent and a return on equity of 10.25 percent.

Ongoing capital infrastructure investment (including replacement and expansion of natural gas distribution pipe and technology) is the main driver of the proposed increase.

The OPUC has up to ten months to review the general rate case filing and issue a decision.
