Electricity again.

I am astounded how some in the government and also the media can say black is white and say it with so much passion.

Yet again we have research from the CSIRO in association with AEMO that shows that renewables added with batteries is lower in cost to old coal fired power stations. It wipes the floor with new coal fired stations.
Yet there was Matt Canavan saying they were dole bludgers only operating when they want to. Does he not know the Telsa battery has saved Melbourne from blackouts which would have been caused by break down in units of coal fired power stations. Where did that power come form. how is SA an energy exporter these days?

Let us examine the problems associated with coal fired power stations.

  • They take a long time to build
  • No investor wants a part of them
  • No financer wants a part of them
  • No insurer wants a part of them
  • They are unreliable. units break down with regular monotony more so nn very hot days when demand id at its peak
  • They emit emissions and pollution
Funny how these problems are either never addressed or ignored.

We do not need any any new coal fired power station. They would add to prices and emissions.

Whoopsy.

I neglected to talk about dispatchable and base load power. They are two different things as has been discussed previously. It takes some time to power ( pun intended) up a base load power station. Dispatchable power can be done in seconds as the Telsa battery has shown time and time again.
It seems after railing against dispatchable power when the NEG was proposed they are now used them inter changeably.
The foolishness of base load power can be seen via a very simple example. Imagine peak demand is 1000 widgets of power.  The power station has 1200 widgets of capacity just in case of the numerous breakdowns.
Midnight comes around and demand slips to 200 widgets BUT supply is still 1200 widgets.
