Xcel Energy & Sioux Valley Energy - SD/MN border
Up until the mid-2010s, this was a branch and interconnect between Xcel Energy's line running east from Rowena, SD and Alliant Energy's line running west from Hills, MN (the intersection is the SD / MN border).
This was once Interstate Power's line out of Hills to serve the last few towns in Interstate's SD system (Rowena, Brandon, and the Valley Springs muni). About the same time Interstate finally left South Dakota, two of the towns ended up going with Sioux Valley Energy as their provider, leaving NSP with the customers at Rowena and rural Brandon / Valley Springs.
In the mid-2010s, Alliant Energy (Interstate's successor) decided to leave Minnesota as well, selling their entire system to a consortium of 12 electric cooperatives, the Hills-area system going to Sioux Valley Energy.
It is at that point Xcel likely went "NOPE", removed the interconnect, and stripped the next 4 miles going west down to 7200V singlephase. They have had ongoing territory disputes with Sioux Valley where the two companies' lines are in close proximity. (see the next pic over for a 'before' view)
