idaho public utilities commission regulatory

"annual rate adjustment filing with the Idaho Public Utilities Commission (IPUC or Commission)"

The Idaho Public Utilities Commission is the state agency that oversees and sets rules for utility services such as electricity, natural gas, water and telecommunications in Idaho, including approving rates, major projects and safety standards. Its decisions are like a referee setting the rules and prices for utility companies, and they matter to investors because rulings can directly change a utility’s revenue, costs and future investment needs, affecting returns and risks.

kilowatt hours technical

"residential electric customers in Idaho using an average of 939 kilowatt hours per month"

A kilowatt hour (kWh) is a measure of electrical energy equal to using 1,000 watts of power for one hour — like counting how many gallons of fuel a machine consumes, but for electricity. Investors care because kWh drives revenue and costs for utilities, energy producers and big electricity users: the price charged per kWh, changes in consumption, and improvements in efficiency directly affect company profits and the value of energy-related investments.

Request would result in higher electric prices effective May 1, 2026

SPOKANE, Wash., Feb. 13, 2026 (GLOBE NEWSWIRE) -- Avista (NYSE: AVA) has made an annual rate adjustment filing with the Idaho Public Utilities Commission (IPUC or Commission) that if approved, is designed to increase overall electric revenues by approximately $25.2 million or 7.4% effective May 1, 2026. This filing has no impact on Avista’s earnings.

The proposed rate adjustment modifies the level of funding for Avista’s electric energy efficiency programs. This adjustment aligns the amount that is collected in customer rates with the actual costs to operate the programs. Avista’s energy efficiency programs are designed to provide a financial incentive or rebate for cost-effective energy efficiency measures. The rate changes proposed reflect the required level of funding needed to operate the programs in the coming year, and to recover costs spent in 2025 that exceeded the levels included in rates. The electric rate adjustment is designed to increase the amount collected from customers by $25.2 million or 7.4%.
