You don't even need to hire a guy, you just go ahead and do it, whether it makes sense or not, because you've got the money. Look at the various lunatic projects the oil states have been engaging in for the last decade or two, where two beers worth of analysis would tell you it's not going to work before you even start.
It's a public company. I seriously doubt the guy is spending any of his own money on this thing. It would be like saying Elon is spending his money to build Tesla factories - he's not, Tesla sells shares/bonds to other suckers, I mean investors, to pay for that.
That's the thing about being rich, you don't even need to use your own money to get even richer.
FWIW the company trades at a P/E of 208 which seems frankly insane for a utility company in a moderately mature industry.
