If I build a house and the demand goes up I don't have to build the solar panels (and everything else involved) to cover it, I pay the utility company to build that based on how much I'm needing to use. Well, normally I pay for whatever they think will make them the most money to deliver that much electricity - Google is specifically paying to make sure they see the utility company sees it as increased demand and revenue for more nuclear.

You'd get denied getting connected or expanding your business or adding a car charger, as is reality in parts of Scandinavia, if it was an issue.
