Week 58

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.

Here in Australia, that level of power is 18,000MW. (See data for the Running Weekly Average For Base Load below)

The Bayswater Coal Fired Power Plant In New South Wales

This data I have collated below is for this last week, and 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 these numbers, that huge amount of power is being supplied mainly 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.

This is the permanent link to all the Posts with the data from each week.

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, the time of minimum power consumption.

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

Comments For This Last Week

As Winter draws to an end, (although some of the mornings are still cold) power consumption slowly falls, little by little, and even though some days show that minimum power consumption at that 4AM point in time still over 19000MW, some days are falling back a little below that 18000MW mark. Even so, the Running average for the week was just slightly higher, but now looks to have reached the highest point for the Winter.

With the time of less power consumption approaching with the benign Season of Spring soon to be upon us, some of the power plants are taking the early opportunity to close down some of their Units for maintenance, and Upgrades. Currently, there are 8 of those Units off line, and five of those are in the State of New South Wales, (NSW) two at the Bayswater Plant, two at the Liddell plant and one at the Vales Point plant. This takes a little over 3000MW out of the NSW grid, and that State is consuming more power from its two nearby States, Queensland to the North and Victoria to the South, via those Interconnectors between the States.

Even so, coal fired power is still delivering a Running Average of just over 81% of that Base Load total.

The Peak Load at around 6PM each evening is now steadying also, and this week’s average was only just higher than for last week, and the coal fired power delivery average for that peak was a little lower than it was last week.

The site where I collect the data for each of the States with respect to the coal fired part of the totals, (shown at this link) upgraded its site this week, and the new ‘look’ for the site is a lot better with the addition of colour to the main graphs, as you can see below. I have used a weekday graph because it has much larger power generation than for weekends, and this graph is for the Friday just passed. For some greater detail, click on the image and it will open on a new page at a larger size.

Here, the black line across the top of the graph shows the total power generation from every source. This is also similar to the total power consumption, which is slightly lower than what the black line for total power generation indicates, after minor grid losses are taken into account.

The dark grey colour is for the black coal fired power generation. The yellowish colour is for the brown coal fired power generation. The purple colour is for natural gas fired power generation. The blue colour is for Hydro (water) power generation. The green colour is for wind power generation. The red colour in the dip between the two peaks is for solar power plant generation. Rooftop solar power is not included on this graph, as this shows just the power generation from all power plants only.

The time line for the day is across the bottom, and is broken down to hourly increments. However, at the actual site, you can hover your mouse on the graph, and notice that it is updated in real time at five minute intervals, indicating the total for each colour, as well as for the black total line across the top of the graph.

It also makes it a little easier for me to work out the average as well, when it comes to my daily Electrical Posts in the other Series I am doing.

As you can see from looking at the graph, coal fired power, the grey and yellow colours make up the bulk of the total for every day.

As I always say, when it comes to coal fired power, there just is no substitute.
