Hey Ross Garnaut SA power prices fell because gas prices fell

I checked gas and electricity wholesale prices data for 2017 and the claim in the AFR Monday – South Australia’s power now cheaper than coal-fired states – Ross Garnaut –
Any notion that this is due to some triumph of wind power fails to examine the dominant driver of SA electricity which is gas. The main sources of dispatchable electricity for SA are the Adelaide gas fired power stations. Then there are the interconnectors drawing on Vic coal fired power.

The three large States which are all dominated by coal fired power are all seeing reduced wholesale prices in 2017 as the Feds and Prime Minister attack high power prices.
