(Portland, OR) -- Power companies are taking action to reduce risk the grid could cause a wildfire. Brandon Capps, with Pacific Power, says they're upgrading equipment to lower the risk. In areas of high risk, they install equipment that's more sensitive to a problem and shuts power off faster. Increased sensitivity also means a greater chance of a power outage when there isn't a problem. Public Safety Power Shutoffs will be used when weather conditions are extreme. People with powered medical devices should contact their utility in advance to see if they're eligible for a discount on a backup power supply.
