A couple of years ago there was a 1.9% increase in your bill from Benton PUD. Starting Oct. 1, 2019 there will be an additional 2.9% increase in your electric costs. So what does this mean exactly? About $3 per month increase for the average customer. It all stems from higher energy costs. That's partly because of things like less water spilling over dams to promote fish migration and that means less hydro-electric generation.
