Hello fellow Wikipedians,

I have just modified 4 external links on Battery storage power station. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:

When you have finished reviewing my changes, please set the checked parameter below to true or failed to let others know (documentation at {{Sourcecheck}}).

Two dead references and an unrelated link in the 'Largest Grid Batteries' section

The references for the 'Tesla Solar Plant' no longer work and clicking on the link leads you to an article on 'Koloa, Hawaii' which doesn't mention Tesla or a battery plant.

Ramp-up

The current language in the lead about ramp-up in "milliseconds" should be verified. The serious sources that I have read say 1 second from 0 to 100%. For comparison, few milliseconds is the time for a typical computer to react to an event. Викидим (talk) 18:51, 17 February 2023 (UTC)[reply]

The rest of the grid usually has momentum which means that the frequency won't drop immediately after a sudden outage, but as the frequency drops it will kick in. So there's a big difference between how fast it can respond, and how fast it usually responds. GliderMaven (talk) 19:01, 17 February 2023 (UTC)[reply]

But if you can find a reference, we can go with that. GliderMaven (talk) 19:01, 17 February 2023 (UTC)[reply]

Here it is: Some battery technologies can ... increase output over full range in less than one second, see p. 30 in

Denholm, Paul; Mai, Trieu; Kenyon, Rick Wallace; Kroposki, Ben; O’Malley, Mark (2020). Inertia and the Power Grid: A Guide Without the Spin (PDF). National Renewable Energy Laboratory.

Pretty recent, should be reliable, comes from people who work on inertial response and thus usually know the ramp-up times. Викидим (talk) 20:16, 17 February 2023 (UTC)[reply]

Country-based Databases needed

Since the number of grid storage plants is now increasing rapidly we need some sort of database entry system so that new projects can be added to easily and the status recorded - planned /under construction /operational / under repair - maximum power output and total storage capacity. Also any incidents . I'm sure someone out there has the ability to create this type of wiki page but I do not! Lawrence18uk (talk) 07:15, 20 October 2023 (UTC)[reply]

Sunlight Storage II

Sunlight Storage II, also called Desert Sunlight II just came online in April 2024 at 230 MW according to the U.S. government (which are all in AC), 300 MW according to news sources - but I could not find the MWhr rating. One sourced guessed 460 MWhr, another claimed 980 MWhr, a third "supposed" it would be 1,200 MWhr. It should be large enough for the list if anyone can find a definite answer to the storage capacity.
