Thread: Big storm and no power in SA

its the big industry complaining the most about power cuts.

i cant remember who it was, but their slag solidified, cost them millions.

The wind generators did continue through the blackout, that's a fact, and now should not trip out. Solar/wind plus batteries will also aid stability.

SA always had this authority. turbo tom was either ignorant or asleep at the wheel.


the majority of wind generators tripped out before they were meant to.

all generators (of all forms) will trip out at 47hz to protect the generator

solar/wind/batteries wont add stability. they add little inertia, no frequency stability.

they are cheap for a reason.

False truths, not inconvenient truths.

Facts are facts, not opinions.

Batteries will be drawn down when needed so that will add stability. Another fact.

it must be hard to constantly argue and fight against renewables and alternate energy production when you full well know it is going to completely consume fossil fuel generating systems in a very short space of time.

you would not in any way honestly consider owning a Ford model T as your everyday drive and fossil fuel power generation is of the same vintage.

these things you want to hang onto , were designed and developed in the 19th century.....isn't it time to redirect your intellect(which you guys seem to infer I don't have) into update, modern, scientifically and now practically proven clean and free fuelling energy systems.

you naysayers use every other modern scientifically proven accessory to your homes and vehicles , why do you hesitate to include renewable and alternate power generation in your everyday life.

would you back the team at the bottom of the ladder to win the grand final?

Batteries don't add stability to an AC system. I thought we had covered that.

You would need to give a large industrial customer too much notice for this to be viable. I can't see this doing anything but pushing more buisness off shore if they think this is what the future holds here - I'd be out of here like a rat up a drain pipe given that option if I ran a large buisness. It's not a solution by a loooong way, just a stop gap - short term bull**** thinking that will cost jobs in the long term.

I could only see residential and small buisness being happy to do this, but you'd need 10's of thousands to sign up to have the impact they are claiming.

And they won't put diesel in - it would send the State Goverment broke within weeks - even if they didn't run, and even if the 2 major players that can do this stuffed everything they could in there we're only talking a couple of hundred meg at a cost of millions a week, and 5 times that if they ran.

Not sure how an option to get paid for lost production is going to send companies screaming offshore. This is about planned shut down of selected high demand processes for an hour or two instead of a total blackout at the plant. That's the point of signing contracts, they have to be an advantage for both parties.

Diesel gensets are one of the options being mentioned by the SA government. Tasmania did it and didn't go broke within weeks, so I've heard.

It doesn't matter how many times you assert this as a fact but the world's biggest battery manufacturers beg to differ. I think I'll take the random internet experts' differing opinions with a grain of salt....
