This article in the hard copy gives a figure which shows a coal fired power plant using Integrated Gasification Combined Cycle with Carbon Capture is economically viable at just over $40/tCO2 carbon price. The type of coal gasification is not stated but above ground is likely. UGC would be cheaper by perhaps 15-20% with extra savings in waste disposal. Solar PV and solar thermal are shown to be way more expensive.

However, this report from the Federal Gov http://www.ret.gov.au/energy/Documents/facts-stats-pubs/EPRI%20Fact%20Sheet.pdf has IGCCCCS as more expensive than a (relatively) simpler super critical pulverised black coal power plant.

Both reports put down solar PV and solar thermal (and most other renewables) as costing $300-$500/MWhr vs IGCCCS at $150-$250/MWhr. Buuuuuttttt - $300-$500/MWhr for PV is $0.30-$0.50/kWhr. Domestic power is currently around 21c/kWhr in most states and heading to at least $0.30/k/Whr largely to pay for network upgrades.

Installation of domestic and commercial PV systems (which displace at retail power rates, not utility production cost) is very close to viable.

Neither analysis has explicitly addressed the rapid fall in PV power prices over the last year or included analysis of how power management (switching off appliances, conversion to most efficient use, ToU) can compensate for some of the variability in output of PV/Wind.
