A very large battery storage site, like the top 10 currently running has an order of magnitude more energy storage than you suggest.

The largest under construction for go live in 2027 has another order of magnitude, 19000MWh and will deliver up to 1000MW.

Things are changing fast as battery prices drop and experience accumulates.

Is that correct only 1MW of power but 19,000MWh of storage? That would take over two years to drain it.

Well spotted, I've corrected to 1000MW (or 1GW).

The UEA are aiming for a longer than usual runtime, but only 19 hours, not 2 years.
