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 the utility company sees it as increased demand and revenue for more nuclear.
