Remember Xcel Energy’s Hollydale Transmission Project that was derailed when it was clear it wasn’t needed, and so Xcel Energy withdrew the application with regular compliance reports on status of the project, and a promise of a need study so long ago???

Yeah, I’ve been forgetting too, it’s been so long.  Here’s Xcel Energy’s page on what’s now called the “Plymouth Project.”

But, here it is!!  Finally, it has arrived, the Hollydale System Assessment Report from Xcel Energy that we’ve all been waiting for:


Pay particular attention to the map above of the “study area,” and note that it is the Interstate 494/694 ring and Hwy 55 to the east and north where the problems are, and the problems are yellow and orange, and not red.  The problems are not in the area of the Hollydale substation and not to the west, towards Medina.

When do we start seeing problems?  Looks like it’s in 2036, 20 years from now, double the usual 10 year transmission planning outlook (hint, that means it STILL is not needed) — and note, again, the problems are to the east and north, along the highways:


I’ve got to scour this report, but I do not think that they’ve considered select placement of distributed generation, i.e., solar panels on all the big boxes in the areas above in red!  Or residential solar on those in yellow.  What’s so difficult about that?

Here’s their choice:

FavoriteAlternativeCOn the plus side, there’s new substations planned in the red territory.  On the minus side, they still want to utilize the Hollydale substation.  On the plus side, they plan to expand transmission using 34.5 feeders, which is what I promoted as a solution.  On the minus side, they plan to keep the 69 kV line through Plymouth, with an eye on utilizing it in the future.  On the PLUS side, they claim that there’s no impact on the Hollydale – Medina section of the 69 kV line, claim that there’s no change from present use and non-use, and for my clients in Medina, that’s a good thing.  On the MINUS side, they don’t propose to tear that “unused” 69 kV line down.  On the MINUS side, they don’t propose to put all the transmission and distribution underground.  And remember, just yesterday, when there was a large distribution outage due to wind out in the western suburbs?

So now, it’s time to read this report!
