If coal and gas stations are keeping prices down how do you explain that over the last 12 months the respective prices paid to generators are
Solar $49/MWh
Wind $78/MWh
Brown Coal $101/MWh
Black Coal $135/MWh
Hydro $188/MWh
Steam gas $190/MWh
CCGT Gas $200/MWh
Battery $267/MWh
Reciprocating gas $228/MWh
OC Gas $349/MWh.
Volume weighted price of wind+ solar + batteries $72/MWh
Volume weighted price of coal+ gas $136/MWh
2. As for those renewable droughts you claim. In the worst day last year renewables produced 58.8% of their average daily output or 22.8% of total demand. Worst week 69% and worst month 74%, so if we have about four times as much renewables as we have now, the back up required will be about 20 GW for 1-3 hours, and there will be a net surplus in every week, month or year.
3. As for cheap abundant coal, where is it? When NSW privatised its coal plants they were guaranteed a coal price of A$27/tonne, now they are paying A$130-160/tonne. BHP claims operating costs for Mt Arthur are A$131/tone, with no profit, no depreciation. how could anyone spend billions on a new coal mine and make money at less than A$170/tonne.
A 2 GW replacement for Liddell would cost about $8bn and operating at 20% more output per MW than the NSW average, would need to earn $70-85/MWh just to repay its loans and investors, $30-40/MWh for operations and routine maintenance and around $50 for coal, giving it a breakeven of $150-180/MWh. A series of wind solar/battey hybrid plants spread across the state with a total of 1.5 GW wind/4 GW solar, 3 GW/12 GWh storage would deliver 10-15% more energy per year, 50% higher peak evening output and deliver power for $90-105/MWh
Have the massive (tax payer funded) subsidies all governments have been putting into renewables been factored into the real cost we are paying for electricity? Labour has been absolutely disingenuous about this when claiming that Australia has the lowest rate of electricity price inflation in the world. Are we different to every other country where increasing penetration of renewables has resulted in higher electricity costs?
Householders might think they are getting "free" power now because of the highly subsidised solar panels they have installed. But what about in 9-10y time when they need to be replaced? You can bet there won't be a subsidy then. So "the piper will have to be paid then" and all this "free" power will come home to roost when the replacement cost has to be paid by those households.
While it is true that solar panels on top of your house might give you some or most of the energy your household needs to function, people are missing the big picture. Solar and wind simply do not generate enough power to meet the energy requirements of factories, hospitals, shopping centres and large energy-draining operations that make our society run. Let alone the data centres generating responses to your ChatGPT questions. If we do not have enough power for manufacturing and basic services, then how are we meant to grow our economy? There's not much point swimming in your solar heated pool if the country can't power itself enough to build, create, protect or grow our nation.
1. This year Texas in 2/3rds of the area of NSW will produce enough energy from wind and solar to power the whole NEM. The EU in 2/3rds the area of Australia generates three times the NEM's total electricity demand from onshore wind and solar
2. Denmark with no measurable amount of hydro runs at 83% renewables, has 25% higher GDP/person than Australia, has a trade surplus, a government surplus and has 16% of GDP from manufacturing vs Australia's 5% oh and lost time per customer of 12 minutes vs 70-150 minutes in Australia
Renewables are be cheap if you forget the need to back them up 100% with conventional methods of generating power that will sit idle while the sun shines and the wind blows and those facilities are given preferential access to the grid. So, one must overinvest in generating capacity to the extent of more than 200%. Is that going to be costless? Lets not forget that the existing transmission infrastructure will be inadequate when one shifts to diverse locations to pick up relatively small increments in additional power. The costing of the renewables scenario is a just a fairy tale.
A new 1GW coal plant with mine, waste dam, cooling water supply is $5-7 bn and at current capacity factors will produce about 6-7,000 GWh/y at an operating cost of $70-90/MWh. Repaying interest and depreciation adds another $70-80/MWh for a total of $140-180/MWh. It will supply a peak of 1 GW and have about 93% availability at 1 GW and will use enough water for a city of 200,000 people.
A series of hybrid solar/wind/storage plants with 1GW of wind/2 GW of solar and 2 GW/10 GWh of storage will cost about supply 7-8,000 GWh/y for a cost $10 bn. Interest and depreciation will work out at about $80-100/MWh and operating costs about $20-25/MWh for a total of $100-125/MWh. It will have peak output of 2 GW, it doesn't require any cooling water or an ash pond.
Chris Bowen is a complete dope. The madness will not reduce emissions by smashing forests for wind and solar and will cost more like $7-$9 trillion as per the Net Zero Report by 2060.
Good to see that you are consistent, if nearly always wrong. But never mind, I am sure publishing these distortions makes you feel better.

Coal is and has been the cheapest method to produce electricity over plant life.
The integrated system plan (ISP) has been proven to be full of false assumptions.

They do easily produce enough power.
