On billsafter the decision
In the same filing as its electric plan, Avista asked for a 12 million dollar, 4.7 percent natural gas revenue increase for January 2027. For a typical residential customer using 61 therms a month that would add about 4.14 dollars to the monthly bill. Washington's Attorney General is also challenging this request; a hybrid evidentiary hearing was held September 17 and 18, 2026, with post hearing briefs due October 19, 2026 and a decision expected around December 2026.
What it means for your bill: This pending case would raise your Avista natural gas bill starting January 2027.
