Regulatory Approvals Provide Foundation for Avista’s Growth Strategy

Avista US05379B1070

Recent rulings from utility commissions in Washington and Idaho have delivered crucial regulatory certainty for Avista Corp. The approved multi-year rate plans establish a clear financial framework, enabling the utility to advance its substantial capital investment program and clean energy transition.

Bolstered by this regulatory clarity, Avista has outlined an ambitious $3 billion capital expenditure plan through 2029, focused on modernizing its infrastructure. This strategic direction is further supported by a recent revision of its rating outlook to "stable" by S&P Global Ratings, reflecting improved financial predictability.

Details of the Washington Rate Order

The Washington Utilities and Transportation Commission (WUTC) has authorized new electric and natural gas rates, effective January 1, 2025. For electric service, the order permits a base revenue increase of $11.9 million (2%) in the first year, followed by a more substantial net increase of $44.5 million (11.6%) in the second year, stemming from a total authorized increase of $68.9 million. Natural gas revenues will rise by $14.2 million (11.2%) initially, with a subsequent $4.0 million (2.8%) increase. These adjustments are based on an authorized overall rate of return of 7.32%, with a return on equity (ROE) set at 9.8%. A new general rate case in Washington is anticipated to be filed in the first quarter of 2026.

Idaho Settlement Agreement Approved

In a separate proceeding, the Idaho Public Utilities Commission approved a stipulation agreement, with new rates scheduled to take effect September 1, 2025. The agreement allows electric revenues to increase by $19.5 million (6.3%) in year one, followed by an additional $14.7 million (4.5%) in year two. For natural gas, an increase of $4.6 million (9.2%) is authorized for the first year, with a minor decrease of $0.2 million (0.4%) in the second. The approved settlement features an overall rate of return of 7.28% and an ROE of 9.6%, assuming a 50% common equity ratio.

Clean Energy Transition Roadmap

Operationally, Avista continues to execute its strategy for a cleaner energy mix. Its 2025 Clean Energy Implementation Plan, filed with the WUTC, formalizes the target of achieving carbon-neutral electricity generation by 2030. The long-term goal is to supply 100% of its electricity from renewable or non-emitting resources by 2045.

Stock Performance and Earnings Guidance

Against this backdrop, Avista's stock is currently trading at a notable technical juncture. Analysis from December 6, 2025, identifies a key support level at $38.57, with resistance observed near $40.97. A sustained move beyond either threshold is viewed as potentially signaling the next significant directional trend. The company has recently reaffirmed its full-year 2025 earnings guidance, projecting diluted earnings per share in the range of $2.52 to $2.72.
