Blah, blah, blah, why does this endless sermon disregard that big old coal fired power can only be run at 100%? Reduced power means low pressure steam danger if condensed water droplets preening turbine blades. Especially with brown coal, quality variations do cause danger of reduced output. Boilers are the height of 20 storey buildings. Conflict between more steam tubes and ash build up and bridging, corrected by shutdown, cool down scaffolding and jack hammers. Corrosion inside as well as outside of boiler tubes, leaks causing ash set like concrete. With Hazelwood, 8 x 200MW turbines, possible to reduce some to idle but newer 500MW are all or nothing.
Does AER not understand nature of problem, ever worse beyond 40 year use by date.
