The June 25, 1998 blackout report needs to be on the interwebs available to the world.

June 25, 1998? That’s the night of the transmission fail that disconnected the Midwest from the Eastern Interconnect. That question was asked by Minnesota Power’s attorney of each and every witness, I think other than MP, but maybe MP witnesses too, in the Arrowhead transmission project hearing, circa 1999-2000. There were cries of “Hospitals will go dark without the Arrowhead project,” “We’re going to freeze in the dark in an incubator” which became “We’re going to freeze in the dark on a respirator without a job” — it was so histrionic.

The Arrowhead transmission project was project 13J of the WRAO Report, and the WIREs Report, which presented many transmission lines, but chose the Arrowhead transmission project as the “be all and end all” of transmission in the Midwest, that it would fix all the transmission problems:

The hearing went forward, 2 weeks in Minnesota, where MP got an exemption from Minnesota Power Plant siting law, and for TWO MONTHS in Wisconsin, for Round 1, then 2 weeks after the cost went way up, and another 3-5 days of hearing later when cost went up again. They got their permit, it’s up…

But in that first hearing, I did get to introduce the report that showed that the June 25, 1998, blackout was NOT caused by too little capacity, it was not caused by an unreliable transmission system. It was caused by corporate greed, transmission operators running the Prairie Island-Byron 345kV’s TCEX flow over the limit, disregarding operating guides, and disregarding requests and demands to ramp the power down, violating MAPP Operating Standards and NERC Operating Policies. SHAME, NSP, SHAME!!! And MP was so tacky, trying to attribute their desire for bulk power transfer to the blackout, that the Arrowhead project would save us. Yeah, right…

Here’s the report, below, it’s a gem, I’m posting this today because I’m shoveling off my desk and there are a lot of gems here, so posting them will get them out into the world in perpetuity — can’t disappear something from the internet! Scanning them in is taking a while, a royal and dusty pain in the patoot, but just for you inquiring minds, HERE IT IS:

Here are a couple snippets, starting with p. 2:

Bottom line?

OPERATE WITHIN OPERATING GUIDE LIMITS!!

DOH!

The report goes on and on with stupid human tricks – the flow was NOT reduced by NSP System Operators:

From pps 10-11:

So if the operators had been doing the job, not focused on keeping that line operating with all that power flowing through it, selling that power, the blackout may not have happened. Great…

And for some reason, NSP operators were not communicating:

300 MW above the operating guide limits:

OPERATE WITHIN OPERATING GUIDE LIMITS!! DOH!

Operator error is a too-generous way to put it — but for the efforts to NOT reduce power flows, the inadequate response of system operators and their failure to communicate the degree of the problem, the blackout may not have happened. And then utilities have the nerve to say that because of the June 25, 1998 blackout, we need the 13j Arrowhead transmission project?
