Wind Generation and the Electricity Grid

[cove]

At our 2 Perth warehouses we now have 110 LED warehouse lights installed so in a month or two we will know if we have succeeded in crushing our work power bills. The power draw readings before and after installation were amazingly different.
So we chose solar and then LED lights to dramatically reduce our grid power use. We have done this nationally.

LED may be giving us headaches.

LED bulbs can bring on feelings of dizziness and pain within just 20 minutes of switching them on, an expert has warned.
Professor Arnold Wilkins, professor of psychology at the University of Essex, said the flickering of the unpopular lights is stronger than for traditional lightbulbs.
While fluorescent lights, such as those in offices, dim by around 35 per cent with every flicker, LED lights dim by 100 per cent. It means they effectively turn off and on again hundreds of times every second.

In the warehouses those LED lights are between 6 and 11 metres from the concrete floor. We haven't gone LED in our office as we are just wanting to get our power usage to a net zero rather than a minus number after our solar power generation.
We are already providing electricity to the grid on weekends and public holidays when we are closed. Battery technology is probably 3 years from being a winner.
We work sunlight hours so solar 3 years ago was a big saver.

Oh dear. Just heard on the Radio that SA has had a 2 year wind drought that is impacting on our energy generation.

Where is the battery?

Not here yet.

Its not our fault. Last time it was a storm that blew down the towers, then it was a dodgy connection from Victoria. Not our fault now that there is no wind.

Very surprising! There's always a lot of wind coming from SA members on this thread.

That's it. They have been too engrossed within AFF ecosystem they neglected to blow in the direction of the windmills:mrgreen:

Moi? Surely not.

on the topic of "less than accurate reporting" I have been look at the aemo website (link at the bottom) and I find it very strange that the Denmark wind farm is always producing at 100% while the Albany farm (50 km east) is rather variable (though mostly producing something). I note that the Albany farm is owned by Synergy, (one of) the state electrical retailer.

I emailed the aemo about the availability of tabular data by day including periods of no production either by lack of wind or administrative decision. Their reply was less than helpful as they referred me back to the farms.

Why is it I suspect political interference?

Nothing new - remember the Bureau of Metereology's "homogenisation" of temperature data that always seem to favour the Climate Change narrative.

 

[drron]

Though now technology has allowed BOM to drop homogenisation for an even better way of getting warmer temps.
Electronic thermometers which measure at each second.The highest 1 second reading each day becomes the maximum no matter whether it is totally inconsistent with all other readings.
So just imagine what may influence a sudden change in temp at official stations such as Hervey Bay airport or Amberley.

And its strange isnt it when temperatures less than -10C at Thredbo top station were either recorded as a blank or rounded up to -10C.

reason given by BPM ranged from equipment failure to technology limitation, to a rounding policy

$60 Billion of REC value has been spent by Australians. Imagine what that could have been spent on.

At least 6 nuclear reactors producing baseload power with no CO2 emissions.

The wind generation in SA for the last couple of days.

As the graph shows, the orange and dark orange bits represent gas – which is also pretty constant due to the new guidelines imposed by AEMO, the market operator. Yellow represents the output of the state’s 700MW of rooftop solar.
But it is the green that fascinates. South Australia has just over 1,700MW of wind online, but it is highly unusual to see it so constant. The reason is that AEMO has put in constraints to limit the output at 1200MW, which it does when it cannot find a fourth gas unit to operate at the same time.

Ummm baseload means 24/365 at constant output.Put up a graph showing wind output over the last year.
There is no way wind power will ever be baseload.
The backlash is starting-

2 day graph?. What about a longer period such as 1 month

Dont forget that yMW installed wind has to be always backed up with xMW from other sources
Problems start when the x is < y because the backup will not be enough leading to load shedding.

So when the Premier says more gas is being built some of that is for backup in case y < x.

so not only is wind expensive in its own right there is an additional cost from needing to build backup sources

 

[drron]

So it looks like SA and VIC are going to get a lesson in the true nature of baseload power-
Risk of blackouts in Victoria on the rise this summer, report warns

And all because of global warming-
