I can’t resist cancelling the units even though it doesn’t actually make sense because it’s a capacity not a volume, as it were, but that’s a 3.6kw factory!
Here’s my working. There are about 31.56 million seconds in a year, which I rounded to 30 million, and so
30 GWh/year
= 30x10^9 Wh / year
~ 30x10^9 Wh / 30x10^6 s
= 10^3 Wh/s
= 1 kWh / s
= 3600 kWs / s
= 3.6 kw
I used the duckduckgo autocalculator just now, and 30/31.56*3.6 is about 3.4, so it’s much closer to 3.4kW.
(It’s not power output, it’s manufactured storage output. I think of it as like a factory that produces 3.4 litre capacity jugs per second, but they’re not jugs, they’re actually batteries. Big ones.)
They could make a 120kWh battery (which would give a family car a range in the region of 450 miles) every two minutes.
(“to the best of my knowledge, that is now, immediately.”)
Yup. BYD’s 30GWh/year means 1kwh/second!

3.6 MW even. :)
3.6 kW is what a 50cc internal combustion engine typically produces
