there's a dead comment from a new account that says this:

"1) regarding price, it's probably PV at those prices, as CSP today comes in at least 2x of PV installed capacity cost and that's taking a very aggressive estimation- although one could probably get CSP costs down to $1/watt with the design and procurement scale economies being talked about. 2) Regarding Venning's point about demand, even with significant amount of energy storage, this would create quite a bit more peak power on sunny days than their current grid demand can handle so announcement may be based on a couple (dodgy to me) assumptions: a) either they assume building it out in phases slowly over time to accompany some aggressive assumed demand growth or b) they are thinking about power exports in a region where Saudi Arabia probably doesn't have too many politically viable customers"
