good point.
no word on that deal. but in the usa it looks like battery adds .015@kwh—this was from a record low contract priced signed in arizona in May by Tuscon Electric Power.
TEP declined to reveal the exact pricing, but the all-in cost for the solar-plus-storage project is “significantly less than $0.045/kWh over 20 years,” said Carmine Tilghman, senior director for energy supply at TEP. And, at under 3¢s/kWh, he says he believes the solar portion of the PPA is “the lowest price recorded in the U.S.”

fyi coal power comes in at above .05@kwh
Next question, what does a battery of 300MW look like??
I work at a coal plant, we can make money at $0.025/KW
There’s a lot of crap floating around out there from Musk about solar panels and batteries running the grid. The MISO footprint runs a summer peak of 100,000 MWs. It will take a while for enough battery packs to run the grid a night when there’s no wind.

A lot of ignorance in that article and on that thread.
