PNNL’s Dynamic Contingency Analysis Tool does just that - helps utilities anticipate and manage power and grid instability during extreme events, like mitigating wildfire threat to the grid, enabling operators to see and reinforce weak spots on the grid to stop cascading power losses or blackouts. The study also found that in the Pacific Northwest and Canada climate change was responsible for about 3.6 degrees (2 degrees Celsius) of the heat shock. So you have to predict what can happen and make sure you're not going to add stress to the system.” If you have a disturbance on your grid, the disturbance can propagate faster than your ability to control it. On the grid, electrons are flying around at the speed of light. Heat alerts blanket the Pacific Northwest, including much of Oregon and Washington state, where temperatures are set to spike to 110 degrees in the days ahead. The week of July 24 marked the most severe heat wave the Pacific Northwest has experienced since the deadly 2021 heat wave broke all-time records across the region. As a national laboratory in service to the nation, PNNL's mission includes grid-related emergency response.ĭagle says that "grid resilience means you are anticipating extreme events and preparing for them. Friday’s predicted high is 93 degrees, and. Seattle hit 94 degrees on Tuesday, 91 on Wednesday and 91 on Thursday. Jeff Dagle is Chief Electrical Engineer at Pacific Northwest National Laboratory and co-director of the Washington State University and PNNL’s Advanced Grid Institute, which works to improve real-time grid simulation so operators can better control it, among other activities. It’s been a hot week in the Pacific Northwest, and the heat isn’t winding down yet.
