Avista Corporation has submitted a regulatory filing with the Idaho Public Utilities Commission requesting a 7.4% increase in overall electric revenues, equivalent to approximately $25.2 million annually. The proposed adjustment, scheduled for implementation on May 1, 2026, aims to address higher-than-anticipated operational expenses incurred during 2025 and align customer rate collections with actual program delivery costs.
The rate adjustment reflects increased expenses related to the utility's energy efficiency programs and other operational factors that exceeded budgeted projections during the past fiscal year. The filing represents Avista's formal request to recover these costs through customer rates, a standard regulatory process in Idaho's utility oversight framework.
If approved by the commission, the average residential customer consuming typical monthly electricity volumes would experience a bill increase of approximately $8.90, representing a 7.7% monthly rate adjustment. The Idaho Public Utilities Commission will evaluate the filing according to established regulatory procedures and cost recovery standards before determining approval.
