Three power companies serve portions of Spring Hill, so it can be a little bit confusing.
Middle Tennessee Electric covers the majority of Spring Hill. They cover all of the Williamson County side of Spring Hill except the Willowvale Subdivision. On the Maury side of Spring Hill, Mid TN Electric covers everything north of Derryberry Lane on Port Royal Rd and from the intersection of Hwy 31 and Kedron to the intersection of Kedron and Old Kedron.
Duck River Electric covers everything south of Derryberry Lane on Port Royal Rd and everything South of the intersection of Kedron and Old Kedron Roads.
Columbia Power covers the Willowvale Subdivision. On the south side of Duplex Rd, they cover Hardin’s Landing Subdivision and everything to the West, and on the north side of Duplex, they cover everything to the west of Lexington Farms but not the subdivision itself. They also cover the Town Center subdivision. As a point of interest on HWY 31, Columbia Power serves The Commons shopping center on the west side of the road and almost to the Captain D’s on the east side.
