Electric Distribution System Reliability and Voltage Conversion Project
Reedsburg Utility Commission (RUC) has been working on a multi-year Electric Distribution System Reliability and Voltage Conversion Project.
RUC’s distribution system currently consists of two voltages (4,160 V and 12,470 V). When the conversion project is completed, our system will all be at 12,470 volts. A higher single distribution voltage will provide increased system reliability and capacity for the continued growth of the Reedsburg community.
Our substation located along South Webb Avenue is susceptible to flooding due to its proximity to the river. During the 2008 and 2018 floods, the substation had to be removed from service. Customers that were normally served out of this substation were switched to other distribution lines from other substations. A blink (an outage of only a few seconds) or outage will impact more customers on these larger circuits. This substation is being replaced and relocated to higher ground next to the bike trail to raise it out of the floodplain. Once this new Webb Substation is completed it will also provide increased system reliability and capacity in the distribution system.
Outages and Blinks:
While these projects are being completed, some of the circuits that feed the north and west sides of Reedsburg are approximately 2.5 times larger than under normal operating conditions. These larger circuits are more susceptible to blinks and will affect more customers. Squirrels cause a majority of the blinks and the incidents are most common in early summer through the fall. Every blink is investigated and additional wildlife protection is added whenever practical.

Our current project schedule is to have these projects completed late summer of 2021. Once completed, circuits will be smaller and customers will have less exposure to blinks. We appreciate your continued patience as we upgrade our electric distribution system. Please call 608-524-4381 to report any electric blinks or outages.
