I refer to taswegen on page one. Your pricing of $85 / mwh is minuscule.
That is 85 cents / 1000 kWh which is 8.5 cents / kWh.
What you need to know where the rest of the electricity charge comes from.
Retailers are the problem.
To be a retailer which is open to anyone, if you read the rules.
The rules say company,s corporations, or sole prioritore.
A global company that does billing for 60 percent of the world charges $1 / customer / month. AMEO reporting etc is all included in the charge.
Are you starting to see where the charges are coming from.
As of yet no sole propiators have been granted a lisense.
Only gigantic multi nationals hold our power costs close to the chest.
85 cents /1000 kWh would be an expensive day, it,s usually around 5..6 cents / kWh.

The market is showing opposite assessments than what is being put out by politicians.

What costs would be incurred should 200,000 people from an Australian region need to be evacuated? That is what happened in Northern California when rain bombs caused the risk of the Oroville Dam breaking down.
Mass evacuations have happened a number of times in the last few years.

Quote from Australian Prudential Regulation Authority:

"Australia's powerful financial regulator has revealed it views climate change as a "material" risk that it will be watching much more closely in its monitoring of banks, insurers and wealth managers.

Geoff Summerhayes, an executive board member of the Australian Prudential Regulation Authority, on Friday made the first detailed comments from a domestic regulator on how they are responding to financial risks created by global warming."

Commit yourself to renewable power for your house. Those in wind areas use a 5kw turbine
. Those with sunshine and no wind use solar and of course power storage.
Convert your lighting to 12 v led.
Refrigerator x 12 volt
There is a whole host of self help available, instead of whining about things you cannot change.
Turnbull is now talking about clean coal. The only clean coal is still in the ground once it is above ground it is very dirty.
