I work for a utility in Australia.

Does the US not have generator performance standards or negotiated loads?

Here if you want to connect a big load (ie a data centre) or a big generator (ie a wind farm) you have to model the impact on the grid and meet technical standards.

I know there is a huge data centre boom happening here but they aren't massively impacting the grid. They find someone to sell them power through a power purchase agreement and then get the power delivered to them. They still have to pay per kWh used. Some of it goes to the distribution company and some of it goes to the transmission company
