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.

Thanks that will be my Xmas reading, a quick read indicates wind for example, does not include any storage cost, so power is there when you want it. But will have to read all 362 pages to confirm that impression.
Realistically people have an expectation of 24*7 power, and thats how comparitive costings should be done, not nameplate, regardless of technology.

I think things like that are what they lump under costs associated with connecting to a the grid by the various generation technologies which they say they don't include in LCOE.

There needs to be a means of storage to stabilise the grid's frequency and voltage when there are large amounts of power being generated by many thousands of tiny generation units all doing their own thing in response to their own micro-climates.

It's a problem now on WA's grid as the increase in residential solar has soared. The local generator (Synergy) is losing money hand over fist and the local distributor (Western Power) is facing rising costs having to adapt its grid to conditions it was never designed to handle.

My last electricity bill was $8, for the quarter. I don't pretend to know how it all works, but that's fine by me. Looking for someone to explain to me how a battery set up would work, before we consider going that way.

I get 54 cents feed in

The advice I'm getting is to delay on batteries by at least two years and instead put on more panels plus a 5kW inverter, which is the limit which can be put into the grid by households with single-phase power.
We're already in credit with 3.1 kW and a 15 cents feed in rebate and are about to double our panels to 6.5 kW with a 5kW inverter.

Be careful, with our Contract, changing the inverter size , invalidates the Contract. Of course our tariff is closed off now, yours may still be open.

Your welcome, why am i not surprised Tombie trumped us all (again)
