Offered storage solutions aren't price competetive.
And the big problem is that a 1,000MW thermal can produce an average of 900MW 24/7....1,000MW solar/wind does around 250MW average 24/7, so you need 3-4 times the nameplate capacity, plus storage.
It means that (for solar), should enough be installed to actually supply the market 24/7 with storage, it will be free at midday, the whole concept of off peak will be eliminated. and be VERY expensive at night when the batteries are being used...otherwise the battery operator needs a couple hundred $ per MWh to cover the lifetime costs of ruining his battery every morning and evening peak.
That last paragraph sounds about right. The Tesla home storage product is presently about $7000, and has an expected lifespan of 5000 cycles before it degrades to 80% efficiency, which is considered end of life.
Utility-scale operations appear to have similar costs to homeowner-purchased solutions. So a field of batteries might not be any cheaper. And instead of being mounted in basements or other places out of the elements, they're getting subjected to the full force of nature. Not ideal for batteries.
Here's the article I cribbed from:
