That's largely true, but on the flipside at least some of the rush of batteries into Texas to do ancillary services and provide redundancy are a result of greedy capitalists seeing the profits a few hundred MWh can get you in Texas (at taxpayer expense!) and rushing in to get a piece of the pie. So, markets!
Wait, how does it work? If the government is using taxpayer money to buy services… that’s not really a free market solution in the conventional sense, right?
Of course if we have to pretend it is to get Texas to do it… fine I guess.
