Australian Base Load Electrical Power – Week Ending 15th July 2017

Posted on Sat 07/15/2017 by


By Anton Lang ~

This is the continuing Post, where each Saturday, I will detail the power consumption for the Base Load in Australia for the previous week. This will show what is actually meant by the term Base Load, and that is the minimum daily power consumption at its lowest point. Power consumption never falls below this point.

The Bayswater Coal Fired Power Plant In New South Wales

Here in Australia, that level of power is 18,000MW.

This data is for the five States connected to the Australian grids, every State east of the Western Australian border, and here I will show that data for each of those five States, New South Wales, Queensland, Victoria, South Australia, and Tasmania.

As you can see from this data, that huge amount of power is supplied by coal fired power, and on most days that coal fired power provides 80% or more of that level of power, at that time, when power consumption is at its lowest level, that total of 18,000MW.

All of this data is taken at a single point in time, and that is at 4AM of every day, when nearly all of us are sound asleep.

For the Introduction and background for this Base Load, refer back to the original Post at this link.

For the purposes of this data, the sources are as follows.

Total Power consumption for each State

Fossil Fuel totals and Coal Fired power totals

Hydro Power totals

Wind Power totals


All these totals are from 4AM on each day.

There are no coal fired power plants in South Australia or in Tasmania

Saturday 15th July 2017

New South Wales – 7080MW (Coal Fired Power – 5900MW)

Queensland – 5050MW (Coal Fired Power – 6000MW)

Victoria – 4220MW (Coal Fired Power – 3800MW)

Weekly Average For Base Load – 18655MW

Weekly Average For Base Load Supplied from Coal Fired Power – 15336MW – 82.2%

Running Weekly Average For Base Load – 18629MW

Running Weekly Average For Base Load Supplied from Coal Fired Power – 15180MW – 81.5%


As you can see here, on no day did that Base Load fall below 18000MW,and on both Tuesday and Wednesday, it was above 19000MW.

Coal fired power supplied almost 80% (and above) of that total power on each of those days, as high as 85% on Monday.

During this week, the total for wind power ranged between 1% and 12.7% at its best, and on each day wind power was only a small part of that total absolute requirement.

Of interest here is that at the 4AM snapshot in time, most coal fired power plant Units are operating at a slightly derated total power delivery, and that power level ramps up to higher levels for the evening Peak Power time at 6PM. At that 4AM time, those coal fired plants are typically generating around 15500MW and at that 6PM Peak time, they are generating around 20000MW, out of an overall total Nameplate of 23000MW. During this week, every one of those 16 Power Plants were generating power, and, of those overall 49 separate Units, only 5 of them were not generating power, probably closed for routine maintenance.

Base Load Power is not a description for a power plant. It is an absolute power requirement to keep Australia actually operational. Take away that coal fired power, and Australia just shuts down.
