>>Many more must be built in the coming decades to modernize the nation’s creaking grid systems and connect far-flung renewable energy sources to population centers. That is straight-up opinion.

Sure, there are some economies of scale, but there are also structural economies and reliability benefits of locating more smaller sources nearer to the power users.
