Did you notice that your plot of electricity demand through the day was for June 9, in Australia?

So peak demand doesn't appear to vary very much summer or winter. Round meal times.

Can you prove that? Why would you produce the daily demand cycle from the middle of winter to back this up?

Yes indeed. So where did I do that?

What I quoted was text from AEMO.

"For many, the Australian summer is a time for family, beach, outdoor fun and keeping cool under our strong southern sun. For the Australian Energy Market Operator (AEMO), summer is also when Australia’s energy system is under the most strain due to high consumer demand (like when we all turn on our air conditioners at 6PM) and extreme weather events like bushfires."

"Energy fast facts

    The power system is under the most strain during high demand days between 4PM to 7PM, most commonly during periods of extreme heat (38 degrees plus)."

The only evidence you have provided showing actual demand levels throughout the day is from the middle of winter

Sorry. That appears to be Gnads. What evidence have I shown for winter?

My bad. Yes, it was Gnads.

So the only evidence that has been presented showing actual consumption variation during the day is Gnads' graph from mid winter showing the evening spike at slightly higher than the midday one, and mine from summer showing one dominant peak in the middle of the day.

except what has been written by the Australian Energy market Operator (AEMO) as I posted.

Most strain (maximum energy usage) between 4PM and 7PM.

yes. if you want another state feel free. Or make an assumption that electricity usage Australia wide would follow a similar pattern. Wink

You do realise it's a screen dump, not an interactive thing right?

Don't you think it's strange that the most basic info on this is so hard to come by?

Australias Stupidity

A nation sleepwalking into penury!

Over the past decade subsidies and hand-outs have resulted in the spending of around $50 billion of our nation’s limited and precious capital on so-called ’’renewables’’ - solar & wind Power.

Untold billions more have been spent to upgrade transmission lines to connect these to the grid.

For that money, we could have instead built 10 new HELE coal fired power stations (which would have lowered Co2 emissions) and had change left over to build 10 new Adelaide Hospitals (the most expensive ever built in the world).

Yet this ‘’investment’’ (or should we say ’malinvesment’) has hollowed out the baseload generation of the nation, causing wholesale electricity prices to triple, and at times resulting in power having to be cut to our nation’s aluminium smelters to avoid blackouts.

And on 9/6/2018 at 6pm, when demand peaked at 6pm, at just over 26,000 MW - that $50 billion spent on wind and solar was only providing 100MW - that’s less than 0.4% or 1/260th of total demand. Bit of a bugger when the wind don't blow and the sun don't glow and the power stations don't go (no more).




Peak demand is actually at midday in the middle of summer - when solar panels happen to have peak output.


Grin Grin Grin

Yeah everyone is at home at midday cooking a hot roast dinner  Roll Eyes

Afternoons into early evenings is the peak period when people are all at home ... evening meals & ACs turned on.

It shows that at around 6pm on the graph ... not the slight rise at 9.00am.

I found the graphs I posted no trouble & they're recent not 4 years plus older.

Yes Gnads, you found graphs from the middle of winter.
