Stop in for a cup of coffee
Basically a daisy chain of giant copper and aluminum wires acting as giant extension cords with transformers. Our power plants, windmills and solar farms here in Indiana, only 3.5 percent stays in Indiana, which powers Indiana fully. The rest is sold and transmitted to such states as New Jersey, Nevada (specifically Las Vegas and Reno) Washington, California. We also supply portions of the East coast.
This past year, due to the contractual requirements, we had to do rolling black outs here to allow the transfer of more power to those states. People here are getting really PO’d about it.
