Thread: Big storm and no power in SA

Interesting.

The Projects manager was having a chat with us today. As part of his job, he gets and reads AEMO reports. The latest report shows the towers came down after the blackout occurred. Just before the blackout occurred, six wind farms of a little over 300MW were lost from the grid being the catalyst that started the events that brought the grid down.

The suspicion in the office was that those wind farms, like the two locally, were shut down due to high winds to protect the assets.

Let me draw your attention to:

In South Australia that so-called "synchronous generation" is provided mainly by gas generators, and through the interconnector.
Wind energy is asynchronous, and as such does not provide the same system stability, or inertia.

In the wake of the storm, the wholesale electricity market in South Australia has been suspended, meaning AEMO can direct when and how much electricity generators can produce electricity to ensure stability of the system.

Next stage - Get Trump to build a wall between the states?

Or FedExit vote in the states..

I think if Trump gets in he'll start WW3.

Yes, I also read elsewhere that the market which resulted from privatization has been suspended and they've back to a centrally-controlled system.

Geez, rarely on the forum anymore, but rose coloured shades are still worn by some!

Spinning masses of copper, baseload generation are what is required for grid stability........SA has little of this, the reliance and being hooked to VIC via interconnector, for grid stability is a problem.....the state should of self sustained, with appropriate load shedding and outages, but it can't, cause it it reliant on renewables far to heavily, none of which are Spinning masses of copper!!

Mick has given you enough facts...yes, facts.....so you change the reason of fault to privatisation?.....its simply the lack of base load generation, within the distribution area thats is the major problem, the fact the interconnector was lost, highlights this....it highlights the reliance on baseload generations, from VIC

I can't believe people argue black and blue otherwise, against, actual happenings and logic, Ive worked heavily in the power generation industry, distribution and part of my business sells renewable energy

Without baseload generations, the eastern sea board grid cannot remain stable, simple

How you choose to generate that baseload generation does not matter......but it needs to be....you guessed it....spinning masses of copper.....big **** off turbines!

Unfortunately S.A and Tassie, have adopted welfare support as a state right, where's my electricity, but someone else out of sight can shovel the coal.

Edit, my understanding was the interconnects for both states are supposed to be a two way traffic, not a permanent suck on the teat

Of course baseload is needed as part of a national grid. Like Qld, SA has gas but it didn't perform. It appears the wind was operating and didn't cause the shutdown. The two interconnectors to Victoria shut down when the loss of more than 20 towers destabilised the grid.
The answer is NOT to claim that any particular part of the grid caused the shutdown. The answer is to increase the interconnectedness of the east coast grid. That's why Friday's meeting included talks to establish 2 new interconnectors between SA and NSW. That was the single most important decision to result from the situation, I think.
Victoria's dirty old Hazelwood may be shut down as early as next year. That will highlight the need to abandon state rivalries and move to a national system, which will include increasing use of renewables. Tasmania already has 90% renewables. As more houses go solar and as battery banks fall in cost that renewable source will also decentralise the system.
