Eastern Interconnection

It was the PJM.

We based this on our, um, integrated or kind of our E-eastern Interconnect model.

So we have all of the, uh, North American various regions modeled.

We have Eastern Interconnect.

The mental model for-- to think about North America is it's actually set up in, in three major interconnections, um, that actually span across, uh, Canadian and US borders.

So, uh, the Western Interconnection, uh, the Eastern Interconnection, and then, um, ERCOT or the Texas Interconnection, and each of these run as their own, um, giant machine, uh, with very little interconnection points between them.

Um, very little in the way of, uh, ext-- next to nothing in the way of, uh, AC or alternating current lines.

Uh, there are a few direct current lines, uh, that connect these two, these areas, but for the most part, um, you should think of them as, as their own, um, separate grids.

So the Western, uh, Interconnect would include, um, British Columbia, Alberta, uh, and then all the western states going down to, to California, Arizona, um- Uh, Colorado, et cetera.

Um, the Eastern Interconnection on the Canadian side would be, uh, Saskatchewan, Manitoba, um, Ontario, and then everywhere south of that.

Um, so getting into the Midwest states, uh, New York, New England, and then, uh, running all the way down into Florida.

And then Texas, um, liking to do its own thing, has kept separate all these years.
