The levelised cost of electricity (LCOE) for a range of technologies is tabulated in this report. The LCOE captures the average cost of producing electricity in Australia from a range of technologies over its entire life, given assumptions about how the generator will operate.

At the time this report was prepared (2015) all new technologies had higher LCOEs than the current Australian grid average wholesale price. No single technology is optimal across all metrics. Of the renewable technologies, wind power had the lowest LCOE. However, natural gas combined cycle and supercritical coal fired generation had the lowest LCOE of all the technologies covered in this study.

The study estimated the LCOEs of various technologies out to 2030. It found the overall ranking of each technology's LCOE was not projected to change from 2015 levels but it was likely the difference between lowest and highest cost technology would decrease.

The LCOE rankings of a carbon emissions price was studied. In 2015, for wind to be competitive with the lowest LCOE fossil fuel generator a $30/tCO2 penalty price needed to be applied. For solar a $70/tCO2 penalty price needed to be applied.

The study noted LCOE does not capture the cost of interfacing with the grid, ie LCOE's for all technologies are calculated at the generator's boundary. No allowance in LCOE is made for the costs associated with connecting / interfacing the various technologies to the grid.

I think LCOE is skewed in favour of coal and gas generators as they can profit from "peaking" in our distorted energy market,(think of it as a subsidy), solar & wind without storage can't do this. Also I'm not sure where the report attributed the gains that energy suppliers made from paying for diesel generator owners to run their sets during "peaking". Having said that I think the rooftop solar has all but eliminated the afternoon peak, as I know of places that used to run diesel gensets every hot afternoon in summer form approx. 1400 to 1800 whereas that is no longer the case.

Someone else come up with 'subsidy' theories in another thread. Load of bollocks as was explained by another in that particular thread.

Cost of Solar Power vs Cost of Wind Power, Coal, Nuclear, & Natural Gas

Actually fairly serious, i live in an off the grid environment, (shock oh horror oil palm) where we make about 8 MW of power

Based on our costings for a 1 MW plant and/or several 500 kva plants our costings give us:
Existing steam turbines, using biomass, can improve efficiency, almost free power, however 11,000 v transmission lines make it expensive for centralised power.
Some new Hydro plants, capex is high , but a 20 year + life with minimal maintenance
Diesel generators, less capex , but high operating costs and fairly short life.
Most expensive for 24/7 power is Solar/battery by a long shot, (no subsidies)

Hydro is probably option 1 to replace some Generators, if we can allocate the capex,
Option 2 is probably a hybrid solution.

On reflection our Hydro is fairly optimal, 50 m of head over a few 100 meters and 5 m of rain. Not everyone has that luck

We get 44c feed in tarriff, which is totally crazy, but never a bill is seen. And thats with 3kw

The approach that these guys are taking solves alot of issues I currently had with most of the current nuclear power plants around the world. They where on the brink of building a pilot plant in China just before Trump **** canned the trade agreement with China

I've always been grateful Microsoft dont make aircraft , but now nuclear power plants. Talk about the Blue Screen of Death.
But good luck to him, at least he is contributing to looking for a solution.

It's too late for them now to come up with another design as the cannot sell kW as cheaply as renewable by an order of magnitude at least.

So like Wivenhoe Dam or the broken one up the coast, insured by the State (Crown) whats the difference.
Do you think there is a insurance policy on the Gateway Bridge for example

Nuclear can rarely get insurance and requires massive taxpayer underwriting.
The world has moved towards privatised electricity generation so that means nuclear can't get insurance so can't be built without government subsidy.
Operating costs for renewables are lower than for nuclear, coal and gas because sunlight and wind are free.

Mick, you keep saying cheaper, but show us the numbers, my attempts to do off grid power in the MW range dont gel with this statement.

wow! i get i think 12 or 14 cents feed in.

We get 7 cents feed in.
