every coal fired power station in Australia was built with government money.
Taxpayer's money and it was not a subsidy. The Government does not "have" any money.
So AGL is going to invest in power production that is not base load. This means that they can come into the market when power is in short supply and charge whatever the market will bear.
To replace Liddell, they are going to have either a large gas fired station or massive PV/wind and a very large storage system, not a piddling little system that has recently been installed in SA.
The deficiency with Liddell closing is 1000MW. Liddell could produce this day in and day out. Even on cloudy windless days.
How big will PV/wind production facilities and the storage system be?
How long would the storage supply last for and at what rate?
