How does the .au situation compare to .uk?

From what I can see they have 73% coal, 13% gas, 7% hydro, 4% wind, 2%
solar, 1% bio.

"Turmoil in South Australia's heavily wind-reliant electricity market
has forced the state government to plead with the owner of a mothballed
gas-fired power station to turn it back on.

The emergency measures are needed to ease punishing costs for South
Australian industry as National Electricity Market (NEM) prices in the
state have frequently surged above $1000 a megawatt hour this month and
at one point on Tuesday hit the $14,000MWh maximum price."

No power generation by nukes, much better situation for
solar and for using pumped water for load balancing etc.

That raw data is always a bit misleading. For example most of
the gas isnt baseload power generation in the east of the country.

"Turmoil in South Australia's heavily wind-reliant electricity
market has forced the state government to plead with the owner
of a mothballed gas-fired power station to turn it back on.

That mangles the real story.

The phrase "heavily wind reliant" did make me wonder, considering it's
only 4% of the total. Does your grid publish operating reserve figures
like ours?

Yeah, South Australia is part of the SE Australian
grid which includes the bulk of the coal fired power
stations and the Snowy Hydro system which is a
****ing great pumped water load balancing system.

Does your grid publish operating reserve figures like ours?

Not that I am aware of.

I see that includes Blowering Dam, where Ken Warby became the Fastest
Man on Water.
Some system, that.

Yeah, and that is just one of the dams.

Isn't that 4% of entire national capacity not just South Australia?

Seems like it, also seems the $14,000/MWh wasn't an actual "market"
price, but is the predetermined "value of lost load" figure that gets
automatically applied when they start eating into the contingency.

It isn't much higher for South Australia alone in the sense
of power actually produced instead of just installed.

So what are the profit and loss sheets per windmill or mill-farm?
I gather the reason behind investment in them is that you can screw a fair bit of the packaging in maintenance fees. What do they average out at?

Pretty pathetic. Not viable without a subsidy.

That isnt the reason for them.

Off peak power supplies?

No wild inept guesswork?

Chase it up for yourself.

Besides that one

Off peak power supplies?
(since their only reason for existence is that they will be used when and how the wind blows.)

Obviously nobody is going to be able to rely on them when peak needs speed needs so it has to be that one?

Nope.

Chase it up for yourself, I only do wild inept guesswork.

You obvious;y don't know how this small jot of the Intertubule works: You ask a question and you get an answer. You do not do it yourself and you certainly do not (whatever the incentive) under any circumstances tell the poster to chase it up for themselves; it makes it looks like you don't know.

What you do, without giving to much of the game away, is to find out how much the other poster knows. Not how much he thinks he knows -how much he knows!
