To save others googling: https://en.wikipedia.org/wiki/Dinorwig_Power_Station - cheers for the interesting read!

Wow. When notified in advance, Dinorwig can go from 0MW to 1800 MW power delivery in 16 seconds. Unprepared, looks like it takes a couple of minutes.

Absolutely breathtaking inside that place.

Rimmer: We can’t afford to take any chances. Jump up to red alert.

Kryten: Are you sure, sir? It does mean changing the bulb.

Worth a visit https://www.visitcruachan.co.uk/ and if you go by train it's discounted

Seems puny compared to the twin plants on the Niagara in the USA/Canada (both are pumped-storage hydro):

2,675 MW: https://en.wikipedia.org/wiki/Robert_Moses_Niagara_Power_Pla...

1,997 MW: https://en.wikipedia.org/wiki/Sir_Adam_Beck_Hydroelectric_Ge...

You're comparing apples to oranges. They're not pumped storage stations.

Technically, they're actually both:

"Water enters the forebay via tunnels from the Niagara River controlled via the International Control Dam upstream of the natural falls. Water in the forebay is then either pumped up into the upper reservoir or immediately sent down over the escarpment downstream of the natural falls into the Robert Moses Power Station turbines."

So, it's like more like Malus pumila (Domestic Apple) to Malus sieversii (Wild Apple).
