Power generation issues in South Australia

 
  steam4ian Chief Commissioner

People who want 100% reliable power should always install generators.

No distribution or transmission system is 100% reliable but failures are infrequent enough for consumes to become complacent. This is that state of play in SA.

There are generation problems mostly caused by economic and political factors. When it is available cheap wind produced energy swamps the market causing generators capable of supplying constant power to drop out of the market or sell much below real cost. The reliable generators have to recoup their cost by charging higher prices when the renewable sourced energy is not available.

SA power prices are high because we are in effect paying for two lots of generation.

That's a theory, but I don't think it's based on fact. Everyone knew, during the last heatwave, that the price offered by the generators was going to spike. The retailers knew they were going to be hit with an $85million bill that they would have to wear. I call price-gouging by the electricity generators, not because they have to, but because they can, because of weak legislation that allows them to.

Petrol generators have been selling out across SA in the last few weeks - seems many people don't want to be caught short again. It's not acceptable that the grid isn't reliable, these are issues from 10-20 years ago not the 21st century.

Actually it goes back a lot further than 10-20 years try 40 odd years or more. You would still get small blackouts though due to a tree branch or car crash taking out the power pole or wires  in a local blackout but large blackouts like of recent years where not the norm and certainly not blacking out the whole state either.

I thought the days of blackouts were a thing from my childhood I am 62 and back then we did get blackouts but the infrastructure back then did actually stay put and not collapse even in high winds and torrential rain etc. Yes we had one in one hundred year weather extremes even back then. These days it seems a slight breeze or a couple of drops of rain and something fails!

There was a state wide blackout way in the early 1980s when a couple of Pipelines Authority workers accidentally cut the gas supply to Torrens Island which then had to be cold started taking the best part of the afternoon.   The gas was off for less than a minute.   This event was always referred to in hushed tones at the Pipelines Authority as "the 30th June Affair".

Blackouts due to weather events are common where there is vegetation overhanging power lines (which tends not to be in the metropolitan area).

Kangaroo Island has also had blackouts through some clown or clowns shooting out insulators somewhere south of Yankalilla.   I imagine this is not restricted to Kangaroo Island either.

When I was in Ontario for Christmas in 2013 an ice storm went through a path roughly along the Great Lakes from Chicago to Quebec City and beyond.    It knocked out 300,000 connections in the area served by Toronto Hydro alone, so we are not alone in dramatic weather outages.    Toronto Hydro had all but 30,000 reconnected by Christmas 4 days later.

Only unit B1 at Torrens is currently generating (at full output 200MW). Pelican Pt offline.  At 1855 Adelaide time demand 1945 MW, thermal 888 MW, wind 555 MW, import 502 MW.   Lack of Reserve 2 has now been cancelled.

AEMO has cancelled planned work on Heywood - Mortlake line over weekend to avoid risk of SA islanding.

Update at 1915: PPt is now ramping up.

Meanwhile the SA Government is going to build Australias largest battery and a new power station, so hopefully these should help ease our power woes. Razz

And you believe that Heath, there is an election coming up and they will promise anything to get re-elected, never believe what pollies say before an election as the promise's are usually forgotten very quickly if they are put back into power. It has been like that for ages now.

Just think of what this state would have if all the political promises were fulfilled!
Decaying freeways everywhere in need of urgent replacement!
The cleanest drinking water in the world!

Electric suburban trains older than the Red Hens!
Heavy Rail to the North East suburbs (and NO O'Bahn)

Then all the rail would have been converted to busways (if a certain party had gained power)!
and God knows what else!

And by the way the battery power will most likely be built and owned by Tesla with the state paying for it (through the nose)

If they're Tesla batteries I'd be a bit concerned, actually I am it concerned regardless of the battery storage suppler.

When we gave some Tesla batteries a test we got some pretty disappointing numbers out of them. We had an inverter with a not too shabby 95% efficiency measured on it - the manufacturer quoted better, but hell, we think the marketing wanks got a hold of the specs.

We found the total efficiency of energy in - energy out was only about 86%, that was a little disappointing - Tesla told us DC-DC 92%, but unless we are running the grid on 48VDC there are other numbers at play.

We are told 100MW of storage, more interesting I think is the discharge rate, the batteries are only rated to 0.2C continuous and 0.33C peak, we gave them a piping hot supper, pulled 0.4C but delta T got to the point that we became concerned for the overall safety of the test.

On the basis of what we saw, the claim that 100MW (actually 87MW) is 'enough for one suburb for an hour' actually means 'we can supply two dozen streets for half a working day' - very different to what is claimed. 1C discharge is a dream claim that just doesn't exist.

Oh I forgot, Tesla also state their batteries could be discharged to near 0%, but in doing so shortens the life to 500 cycles, discharging to 75% allows ~2000 cycles - that's about 5 years, and the batteries will be U/S.
