Construction at Port Madison Substation starts in late April 


In the coming years, PSE will upgrade our three substations on Bainbridge Island to improve electric reliability and capacity. Starting this spring, we’ll replace aging equipment and complete some upgrades at the Port Madison Substation. This work will start as soon as late April and continue through this fall. We’ll continue to provide safe, reliable energy during construction and will minimize community impacts as much as possible.

To prepare for this work, we’ll trim some trees along the existing power lines that feed the substation from across the bridge. You can expect some traffic impacts from time to time as we bring in and remove equipment at the substation. Thank you for your patience!
