2nd MISO Tranche 2 project

August 31st, 2025

Next up, MISO Tranche 2’s #20, Public Utilities Commission Docket CN-25-116, adding a second circuit between “Bison” and Alexandria. The PUC is seeking comments on their Notice Plan, as with the previous MISO #21, CN-25-111, Iron Range – Arrowhead docket. (catch up on MISO Tranche 2 HERE – 24 projects at $2.1 BILLION)

I quickly slapped together No CapX 2020 Comments based on the ones I’d filed the day before on the first MISO Tranche 2 project, further below. Again, this is “just” adding a 2nd circuit, but the “need” question remains — why is this needed — justify it, it has to be more than MISO/MISO’s utility & transmission members want it. MISO’s “approval” does not mean it meets Minnesota’s need criteria in Minn. Stat. 216B.243:

And for that other project, MISO’s #21, PUC Docket CN-25-111, the only Comments filed last week — ONLY THREE COMMENTS. This is a new greenfield project — what does it take to wake people up?
