Ellendale 345kV Expansion

PROJECT INFO

The Ellendale 345kV Expansion project is an extension to the Ellendale 345-230kV Substation for Montana-Dakota Utilities. Construction started in late 2019. We started in late November on a few removal items at the 345kV reactor. Next the foundation crews had to install 10 concrete drilled piers in December 2019. In January 2020, we installed the 345kV reactor switcher for the existing 345kV reactor. Additionally, there are (4) 230kV capacitor banks that we will install through the winter and into the spring of 2020. This project will be completed by the middle of April 2020.
