(Portland, OR) -- PacifiCorp, which owns Pacific Power, will raise residential electricity rates nearly 13 percent this month. The Oregon Public Utility Commission has approved the rate increase for Pacific Power. An average residential customer will see their bill go up around 15-dollars. The increase is due to higher costs to produce electricity and costs to make the power grid less likely to cause wildfires. Small businesses will have a 12 percent increase. Industrial customers will see their rates go up nearly 17 percent. This month, Portland General Electric increased residential rates 18 percent for the same reasons.
