And that's a big part of where data centers come into play.
When you start talking about 100 megawatts and larger, that is not a load to get served at the distribution level.
So that third piece of the puzzle that you were asking about, when you get to more local, like you mentioned the neighborhood, that two megawatt neighborhood is served off the distribution system.
Your local mall is served off the distribution system.
A lot of smaller industrial customers are served off the distribution system.
So those are lower voltage and shorter distance deliveries.
The other thing that's very different between the two, the transmission system is a looped system so that if there is a fault somewhere, you have the ability to quickly continue to move bulk power so there are not expansive outages.
The distribution system has always been designed as a radial system from the substation out to the loads.
It operates very differently than the transmission system.
In terms of voltage, transmission typically runs between 100,000 volts all the way up in some cases to 765,000 volts.
Okay.
A typical distribution voltage is typically 35 kV, 35,000 volts, and down to, in some places, older systems still have 4,000 volts, but most of it's 12, 24, or 35 kV at the distribution.
Yep.
The distribution substations get more centrally located around the load centers that they're going to serve.
So transmission lines fall under the jurisdiction of the Federal Energy Regulatory Commission, FERC.
Okay.
So there's federal permitting that has to take place to approve the need for the transmission line.
And once that is received, then the utilities can go about securing the right-of-way to be able to build the lines where they want to go.
So if you can imagine doing these things, cross-country type of building, and having to buy...
right away from lots of different landowners.
