Fuck these incompetent headline writers who cant use units correctly. At this point they are doing this shit on purpose to ragebait people into reading the article. And they dont even explain what that headline is supposed to mean in the article. Does the output power ramp up that fast or do they mean that it can actually just output a lot of energy really fast?

    I am also fascinated by the measurement “two soccer fields.” Americans largely play soccer on American football fields, so any American would just say “two football fields.” But everyone else hates calling it “soccer” and prefer to use metric rather than comparisons? This just seems like they chose all their measurements to be maximally irritating.

    Calling it two football field would still work. Americans would think brown oblong ball field, everyone else would think black and white orb game. In in all cases they'd be thinking of essentially the same measurement.

    Aren't soccer fields like 20% larger usually?

    Yeah. A lot of USLW games are played in gridiron stadiums, and the touchline is way further out than the sideline. They’re not required to be strictly uniform like gridiron, though, it’s more like a baseball diamond in that regard, so I’m not sure if they’re strictly wider, or just usually wider.

    My interpretation is that it can go from no output up to 1.2GW in milliseconds. Do most big batteries take more time to ramp up to high output?

    Actually, the headline isn't wrong, you just read it wrong.

    The article specifies:

    • 2.1 GWh total storage capacity
    • 1.2 GW peak output
    • can ramp up to that peak output within milliseconds

    Every power source has a ramp up time. Ramping up e.g. a nuclear reactor can take hours, so if demand fluctuates it takes long for it to spin up.

    This one here can ramp up almost instantly to cover for fluctuations in the network, especially those caused by the unpredictable nature of renewable power generators.
