Now that people widely accept that LCOE of wind and solar are less than fossil alternatives, the same people who claimed without evidence that this wasn't true have moved on to baselessly claiming that grid integration costs mean they are still right.

AEMO in Australia has had to put out similar work to this to show that renewables grids continue to save money as they approach 100% clean power.

edit: I googled to find coverage of the recently released report and found this headline:

> AEMO's net zero grid estimates blow out by billions, with coal to endure until 2049 in draft Integrated System Plan

That coal is to remain only because an LNP (right-wing climate denier) state government has legislated that it will remain. The experts say that decision will drive costs up and reliability down, but the headline is trying to attach that to the net zero target they are undermining.

It would be hilariously ridiculous if it wasn't costing people their health, their energy security and billions in extra costs.

I think it's a mix of a few things, one of which is just denying Trump's talking point and therefore isn't new; another repeated point is that batteries are actually fine on this timescale, which is probably worth repeating given how often I find this surprises people.

The new parts, or at least not widely reported if this has been done before, show that these savings are still present even after accouting for:

• The grid needs upgrades

• More things need to be electrified
