I think it was the world's biggest when it was being built,

Nothing like it, the Snowy Scheme always left it
for dead and was done a long time before it too.

although now US and China have larger. The first one to be comparable
in
capacity to a contemporary power station.

That's wrong too.

https://en.wikipedia.org/wiki/List_o...power_stations

That's a misleading list because the Snowy system is lots of separate
pumped
storage hydro power stations all part of the one overall system.

According to your first Wiki link, the bulk of the Snowy Mountain
scheme is simple hydro.

The list may imply that but the reality is very different.

Only one pumping station is mentioned, confirmed as the
Tumut-3 pumped storage system in your second Wiki link.

That is because the complex series of storages isnt
just a set of turbines and pumps for each storage.

It is rated at 1500 MW and was completed in 1974

That was the last in the Snowy system.

http://tinyurl.com/hc7cqqv (Dinorwig 1730 MW, duration 6 hrs,
completed 1984). Marchlyn Mawr, the Dinorwig reservoir, has a
capacity of 9.2 million cubic metres http://tinyurl.com/zvx7lbb
http://tinyurl.com/hr8qwlx , whereas the reservoir at Talbingo
that feeds Tumut-3 has a capacity of 920 million cubic metres
http://tinyurl.com/z8ljova http://tinyurl.com/haonl9r about 100 times
the capacity of Marchlyn_Mawr (although whether all of this is
available to Tumut-3 isn't stated).

It is. And so is all the other storage too.

It is indeed a complex system, but only one section of it can be
described as pumped storage, the power station at Tumut-3,

Wrong. That isnt the only pump in the system.

on that part of the system which moves water north
from Lake Eucumbene and the Tooma reservoir into
the Tumut river and then on into the Murrumbidgee
http://tinyurl.com/jeclz69 , http://tinyurl.com/jd2n49t
and in particular this quote "The Snowy Mountains Scheme
has one pumping station at Jindabyne

Which is in fact involved in the fact that the entire
Snowy scheme is a pumped storage system. It doesn't
have to have that pump at one of the power stations
to be part of the pump storage facility because all
those dams are interlinked.

and a pump storage facility at Tumut 3 Power
Station" from http://tinyurl.com/jgsqrpm .

Unless of course you know better than the people that run the scheme,
in which case you should tell them they've got it wrong.

What they say there is no different to what I said.

You are the one that doesn't understand what they were saying.

The entire system is a pump storage system because all
the dams are interconnected and it is only the oldest
dam, Burrinjuck, which has no way to move the water
that has got there back into the other dams.
