Like I said, inverter based systems have a lot more to go wrong. Ask Spain. There won't be much on the news about it as it is not what the world wants to hear. No one really heard what happened in SA wasn't publicised either. I had to look at the AEMO report to find out the details. We heard little about it and I was working on a windfarm (not one of the ones that tripped off) when there was a lot of the old steam engines on the grid there was enough inertia to react to load changes. Worked for many years. I am not a fan of coal. 

 

As far as underutilised plant, yep the lines may be underutilised in the early morning periods. With intermittent generation they may be underutilised for weeks at a time. The underutisation of coal has been bought in because of the weather dependent intermittent parasitic generation we have put on the grid. We still need it and they still need to make money. Intermittent generation makes power more expensive. Cheap when its running, really expensive when its not.

 

No one said it was just a flick of the pen to extend the life of a NPP but it has been done and obviously economic to do so. Newer plants should be easier, especially if they have 80 years in mind. Is 600 million really expensive for a large plant with potentially a large capacity factor. The windfarm I was on and cost $400 million for 111MW with a capcity factor of somewhere between 29 and 33% 15 years ago. All the large tech companys are looking at using np power. Even looking at restart the remaining TMI reactor. A close on 50 year plant.

 

No one is saying intermittent generation shouldn't be tried but making stupid targets and throwing a heap of tax payers money towards it is not the way to do it. Are you willing to back Australia s future on this. We can see what is happening in the UK and Germany. UK is importing 1000's of tonnes of woodchips from America so they can say they don't use coal anymore. How stupid and ungreen is that . They are also paying windfarms for not being able to get the power on the grid. Is this how the CIS is going to work in Australia. At least they have some NP and building more.  The funny thing is Australia has no hope of getting to its targets. We are at currently 40 % after 15 years and want to get to 80% in 2035. The second 40% is going to be a lot harder because of the extra storage and grid infrastructure that is needed. 

 

France exporting approx 12 GW at the moment @ 52g CO2/kg

Germany 448gCO2/kg

UK 218gCO2/kW

A lot of counties don't have the sun and wind we have there's also tidal which works every day with the tide going IN OR OUT. When you put  steam into the equation it's less efficient and when failure happens it's a sudden Loss of a Large amount and May take ages to fix . It is only efficient at near full output and can't be varied quickly. Brand NEW coal Plant is costly. Carbon Capture and storage is a Myth.  Our demand pattern has changed. Most people run airconditioning and have a fair bit of  refrigeration. Heating water directly by electricity (Elements) is an expensive way of doing it.  

 Solar by concentration can Produce very HIGH temperatures. That's helpful for specialised processes, yet to be realised.  No one can deprive you of solar. Yet.   Nev

But that's what the Vic Gov't want. We have a gas hot water system, had it for 45 years. Within a couple of years we'll be required to replace it with electric.
