Tonight was the public hearing for the Menahga Transmission Project.  This is A transmission project with a pipeline driver.


This is a weird project.  They’re admittedly having problems with the old 34.5 kV distribution system, that was established ages ago in the GRE_Long Range Xmsn Plan_October 2008, and in the last four Biennial Transmission Plans (their application claimed that “this project” had been under discussion since 2007 as project “2007-NE-N3”):

2007-NE-N3_2007 Biennial Transmission Plan

2007-NE-N3_2009 Biennial Transmission Plan

2007-NE-N3_2011 Biennial Transmission Plan

2007-NE-N3_2013 Biennial Transmission Plan where it morphed into “2014-NE-N21”

Check the 2007 map for project 2007-NE-N3:

Does that bear any resemblance to the project they applied for:


Nope, there’s no resemblance, I didn’t think so either.

But I did find this interesting map of the “project area” that shows the 2007 area in question and more easily shows the logic behind their claim that:


There’s that green line right down the middle that’s the focus of the “problems” claimed.  And from that 2007 report:

The Hubbard-Menahga 115 kV line would be the start of a Hubbard-Menahga-Wadena/Compton-Wing River 115 kV line.

Walk through that list of cities, and you don’t get anything that looks like what they proposed.  It does indeed look a lot like fixing that green line that connects all the cities would answer their problems!

In the hearing, I clarified the capacity of the line, which at 140 is 7 times that needed for their 20 MW load (click for larger chart).  Go to the 477 on left side (kcmil) and then scoot over to the “115” column in the MVA rating columns on the right, scroll down to the “140.”  As the engineer confirmed, the 140 MVA is essentially MW…

And here’s the peak demand for the entire area, 16.48 MW, for which they’re wanting a 140 MVA capacity line:


Oh, well, there is that pipeline driver, the MinnCan pipeline over to the Koch refinery, and they want more pumping stations to increase the capacity from 165,000 barrels a day to 350,000 barrels a day.  And they want to double circuit the part on the northern end, from Hubbard substation to somewhere west of that for a “future GRE project” that they will not identify further, but they did not deny that it was Sandpiper (and $50 says it is).

The good news is that there’s tofu in the neighborhood for fortification, should get three meals out of this!
