Dual announcements from Idaho's Public Utilities Commission bode well for customers of Intermountain Gas and Avista.
Natural-gas rates will decline an average 5.3 percent effective this weekend. Something called the Purchases Gas Cost Adjustment is constantly adjusted up or down to account for changing costs of gas supply and transportation. Low demand growth has pushed down rates, resulting in an average of $2.17 of savings per month for an average residential customer.
The PUC also granted Avista a base rate electric increase of about 1.1 percent and a base rate gas increase of 1.6 percent. But because of decreases in other rate components, billed rates for electric and some gas customers will actually decrease, effective this weekend. An average electrical customer should see a 2.4 percent overall decrease and the average gas customer should see an overall 0.1 percent decrease.
