That can't possibly be true. In true dollars Kenya's gdp is 140B USD. You can generate that much products and services on 4GW. That is a single big powerplant. I suspect the author missed a zero somewhere.
Also if they need so much power, why UAE is not also building powerplants? It is not as if Kenya will stop growing.
Doesn't make much sense.
The company building the data center probably doesn't want to also build out the necessary support infrastructure if they could get the government to do it instead, and the president emphasizing that that is a big ask is a negotiation tactic to reduce how much assistance the government needs to provide.
