able to output 1.2 GW within milliseconds

By exploding?

When I flip the light switch in my room, I drain 6 nuclear reactors.

Yeah, that's a bit too much a bit too fast, isn't it?

1.2GWh within milliseconds would be exploding.

Read the headline again, it only talks about GW not GWh. That means it can output 1.2GWh per hour, but it can ramp up to 1.2GW within milliseconds. And it likely can only keep that output for a very short time, which is exactly what you need to balance the fluctuations of renewable energy production.
