> This is a lot of words to say “solar + battery lcoe is $70/MWH and gas is $40/MWH,

No, that isn't what the article says. I'll quote it for you:

    I think it was around $70 for new gas. It was a weighted US average — from memory, but I might be wrong on that.

I suspect your $40/MWH isn't LCOE, it's the marginal cost of producing an extra MWH from an existing plant. A second problem they don't mention for gas is the demand is so high, the wait time for a new turbine is around 4 years. Batteries on the other hand can be bought with very short lead times.

Lazard agrees with you: https://www.lazard.com/media/uounhon4/lazards-lcoeplus-june-...

Marginal costs of $108 for gas peaking and $31 for combined cycle. $48-$107 actual LCOE ($77.5 average).
