Transmission Open House TODAY, tomorrow, and Thursday!
November 17th, 2025
Today is the first of three “Open House” gatherings for the “MariBell” transmission project.
Caledonia?
From the PUC Comment Notice:
This MariBell Transmission Project is a 765kV DOUBLE CIRCUIT project, larger than anything in Minnesota. EDIT after 11/18 open house: BUT the double circuit is a 765kV (5,300 MVA) and the existing 161kV line. they want to follow the 161kV route. THIS is a good example of why you don’t want that 161kV getting its nose under your property’s tent!
We need this WHY?
And don’t worry, this isn’t happening in isolation, as you can see from the MISO map below. TODAY is the last day of the Comment period for the “Power on Midwest” line’s Requests for Exemption (from application requirements) and Notice Plan (how will folks find out about this):
Back to Maribell… (isn’t Maribell the name of some cow?) The MariBell transmission Project is MISO #26 of its “Tranche 2” mega-portfolio of transmission lines in the Midwest:
So far NINE of these projects, MISO #19-26, have Certificate of Need dockets (CN-25-109, 111 & 112, 116-122 — note #CN-25-117-120 have been consolidated under CN-25-117). with Notice of their intent to file applications. “MariBell” is Public Utilities Commission docket CN-25-121 (for Dairyland Power Cooperative) and CN-25-122 for Xcel Energy. So far, no notice if they’ve been, or will be, consolidated.
To look up the PUC docket, go HERE to eDOCKETS, click on the eDockets button there, and you’ll get the search screen. Search for 25-121:
There’s an open comment period now, REPLY comments are due TODAY on the Exemption Requests and Notice Plan (and this map from the Notice Plan is much better):
… so check out the Maribell Transmission Project‘s Notice Plan Petition and Exemptions Request, then pull up the docket, see what others have written, and get replies to those comments in TODAY by 4:30.
