I get that, I'm just disagreeing that we should be looking forwards to storage becoming that cheap. Particularly when our cheap energy sources (solar, wind) have a lot of location specific variability over time.

With some exceptions for sufficiently remote (or sufficiently always-sunny and not too dense) places that local grids themselves are no longer worth it

The original report by Ember [1] is decent but clearly biased.

They assume each battery cycles entirely EVERY day - even in winter. They also assume PV is never curtailed - not even in summer. They of course ignore multi-day weather anomalies. Like wise for weekend/holiday demand variations. etc.

The best part of the report are real world bids of 2025 ESS projects.

I do look forward to local storage getting that cheap. If Standard Thermal (here I am hawking them again) succeeds, we could see local PV-generated seasonally stored 600 C heat at as little as $3/GJ -- competitive with Henry Hub natural gas.
