I agree I don't think it will always be the case but in the 1-5 year term the economics dictate that is what you get, full battery backup to run something like a data center is expensive even if technically feasible. It is not 1:1 backup but significant additional marginal gas production is going to come online with battery and solar build outs, that is what you see in grid queues across the US. You are ignoring the fact that batteries like many other flex grid assets have diminishing marginal returns to arbitrage power. That is why you see them in composition with other flexible base load resources in a market system. We could reform the system to have other objectives.
