October 11, 2019, Avista Corporation (Avista Corp. or the Company) and all parties to the Company&#8217;s Idaho electric general rate case reached a settlement agreement that has been submitted to the Idaho Public Utilities Commission (IPUC or Commission) for its consideration.

The settlement revenue decreases are based on a 9.5 percent return on equity (ROE) with a common equity ratio of 50 percent and a rate of return (ROR) on rate base of 7.35 percent, which is a continuation of current levels.
