Xmsn – Iron Range-St Louis Co-Arrowhead 345kV
April 1st, 2026
________________
Next week, Monday April 6th and Tuesday April 7th, there are meetings about the “Iron Range-St. Louis County-Arrowhead” transmission line, or “ISA Transmisison Project,” and an online meeting on Thursday, April 9th.
BE THERE OR BE SQUARE!!!
In the Notice are directions to show up at the online meeting, Thursday, April 9th, and the full Notice is right below:
Read the section on what this meeting is about on pages 3-4 of that Notice.
Comments are due by 4:30 p.m. on April 23rd:
The biggest problem with this line that I see is that ATC, and now MInnesota Power, are wanting to eliminate the 800MVA limitation on the Arrowhead substation, a limitation that’s been in place since 2001. And what’s really weird is that in the HVDC Modernization Project, at the Arrowhead substation and the DC line, CN-22-611 and TL-22-607, ATC wanted to hijack the Minnesota Power project, and Minnesota Power was not having it… yet now it’s OK… a complete turn around. Hmmmm, wonder what happened there?!?!?! What does this new project have to do with that Phase Shifting Transformer at Arrowhead? Well, for sure it’s connected, so putting more electricity into the Arrowhead substation, that’s simple enough.
And then there’s MISO, today saying, not to worry, this is NOT to power the Hermantown Data Center… which then reinforces the notion that it’s for export, bulk power transfer!
Where is the increased power coming from — the DC line? From Manitoba Hydro? From CapX 2020 connecting in — after all, it’s ALL connected! Inquiring minds want to know. Why? There’s a Presidential Permit limiting power coming across the border to 833MW.
And the purpose of the Arrowhead limitation was to prevent bulk power transfer of North Dakota generated coal. What coal plants have shut down??
I’m representing, STILL representing, World Organization of Landowner Freedom, it never ends. We were an intervenor in the Minnesota and Wisconsin dockets for the Arrowhead-Weston transmission project — that was 25+ years ago, with a couple iterations I think the last in 2004. WOLF was not allowed to intervene in the HVDC Modernization Project when that limitation of the Phase Shifting Transformer was at issue!
Way back when, we were at the MN Appellate Court about this substation and Arrowhead transmission project exemption from Minnesota permitting by EQB in 2001-2002 and got nowhere:
So here we go about that Arrowhead substation again, and about the bulk power coming into the substation, in this “Iron Range to St. Louis County to Arrowhead” transmission project.
