Thread: Big storm and no power in SA

I assume you sell equipment mainly, not so much the free stuff that comes out of the sky. How many kW rating is the biggest system you have sold/installed? Currently, with another 275kV line back in operation tonight, wind is providing just over 1GW of power in SA, not unusual for this time of year...

I'd say something like I have made a deal with Mother Nature and sell the energy that can be harnessed from her.....but ain't no man able to understand women.....if it was father nature, no doubt a deal could be struck...

Thats great, but it's not baseload generation

So, you are TELLING me I have no technical knowledge on this subject.

You have absolutely no idea of my background.

You spout ideas from books that you have read.

And you don't sell renewable energy either.

I think you have an ego problem.

I don't need an idea on your background, I don't need too, to know that you are lacking technical understanding on the subject, read mick marshes posts, they are extremely factual and informative and written in way better words than I am capable off

Books I have read? Huh? I worked for powecor and silcar high voltage and electrical services, also worked for yallourn energy, I'd say it may have a little to do with industry exposure....books I've read? Bizarre

I don't sell the sun, nor the wind no...good pick up and my lack of England skills by bee_utey, humorous really

No ego problem, I'm not emotive, I just prefer people had their facts right

You still haven't told me, how you are going to provide grid stability?

But you would know that had you read my earlier post.

Importantly:

I don't know how many times I have to say this before it sinks in. Wind is only good for line regulation.

I am all for renewables but the right type of renewable power station must placed in the correct location to provide system stability.
And, as it is a private energy market, this must be done, and paid for, by private companies.

The 1MW geothermal pilot plant in the Cooper Basin was a success. They drilled down to some really hot rocks. A larger plant has the capacity to provide the stability the SA grid needs. Problems are it's expensive, remote and requires expensive infrastructure with high losses to get the power to Adelaide.
They did test drilling all over Western Victoria to site one. It's an ideal spot to have a large power station. Problem was they couldn't find any rocks hot enough.

Lets not fight guys. I'm learning stuff.
That geothermal information is interesting. If only they could get that happening it would be good for grid stability.
As I see it as a non-expert, its not about coal OR renewables, that is a pointless dead-end argument. Instead, its about a widening range of power sources, each with advantages and disadvantages, connected by an increasingly-interconnected national grid, with improved management on a national rather than state level. Do you agree?

Discomick i agree with your non emotive summary

Bazinga!!!


The grid is just fine. It should be more local.
When you make it national, all sorts of problems, inefficiencies and losses creep in. WA has several grids.
That is not to say they shouldn't be connected nationally. That is all about selling cheap power to another state at a higher price. i.e. it's about the money.

Like $70,000MWh having seen the spot pricing at times it mind boggling.

The plant areas actually shut down at certain times as it's cheaper/profitable to pump power into the grid than to consume from it..
