What you're touching on is an ancient debate :) Should this part of society be top-down planned or should it be market organized?

I know how I feel about this - I much prefer price signals here; it allows any developer that can meet the spec to build energy production - distributed decision making over centralized decree - and it allows the other side of the equation, consumers, to decide they'd rather not pay for this generation: Curtail demand rather than increase supply.

Like - maybe I don't want to pay energy prices this high, I can choose to insulate my house better or get a heat pump and thus reduce my electrical bill. The price signal lets everyone in the market choose how to act, rather than a central authority declaring we must build, say, more gas turbines and share the cost of that across rate payers.

But, there are people much, much smarter than I that completely disagree with this position. In the end I think the answer is how you feel about human nature, the capability and shortfalls of markets and the complexity of deciding how societies' resources should be allocated.
