I think that you're probably right about gaps remaining, for basically the reasons you have given. And for that reason I don't expect mass demolition of American gas plants in the 2030s the way there was mass demolition of American coal plants in the 2010s. The growth of gas capacity is alarming to many environmentalists; the phrase is that we're "locking in" decades of high emissions from gas fired electrical generators. But gas plants release the vast majority of their emissions during operation, not construction. Diminishing the plant load factor of gas plants is as good from an emissions-cuts standpoint as tearing them down. What do you do when the wind isn't blowing, the batteries are discharged, and it's night time? Burn gas. But the number of hours per year where at least one of {batteries, wind, solar} can bid below gas will go up year after year, whereas that number was essentially holding steady at zero through the whole 20th century. This brief sketch is most applicable to deregulated electricity markets. In markets with regulated utility monopolies, unfortunately, gas plants will be subject to less competition even if the cost of storage-backed renewables keeps declining steadily. The majority of US electricity consumption now takes place in deregulated states but it's far from universal. https://www.electricchoice.com/map-deregulated-energy-markets/ https://www.electricchoice.com/map-deregulated-energy-market...
