To improve South Australian grid security AEMO made recommendations to keep more “real” generation online. Real = “fossil fuel” which for SA means only gas or diesel. The SA Govt created its Energy Security Target (EST), a key plank of its $550 million energy plan. The EST is in fact a reverse or counter RET – so the EST was a sound move to attempt a bandaid repair of the damage caused by destroying the coal fired power stations in Port Augusta. Now we see the mega-powerful renewables/storage lobby has monstered the SA Govt who have now postponed EST to the outer darkness in 2020. You could not make this storyline up.
Reading down the ABC page time and again I am thinking – “mention the Hazelwood minus 1600MW that Vic has next summer compared to last” – But no – Hazelwood is never mentioned. The author also never makes the link to NSW that just survived a blackout on 10 Feb this year. So next summer SA – Vic – NSW are 1600MW more likely to be in load shedding events compared to last summer – more than ever weather dependent. Mad.
Just wanted to get these charts of generation and demand out re the near blackout event last Feb. Full month large chart. Remember Liddell is slated to close early 2022.
3 days large chart. Intro from AEMO report – Keystone cops would have been right at home. In a nutshell – coal gen was off its highs achieved on 5th, 11th and at end of month. Gas was below specs. due mainly low gas supply – ironic for a State with gas exploration bans. Imports were spikey and Hydro were the big heroes in preventing blackouts. Wind ebbed away through the afternoon as of course did tiny solar.

While wind was strong South Australia had a ~quarter of the day on the 22 July 2017 at an AEMO wholesale (RRP) price of minus $60 per MW hour(check SA & 5 Min). In a year of watching AEMO data I have not seen such an extended period of negative RRP price. Now we all know that the gas fired generator(s) that continued working with AEMO RRP at -$60 will not mail cheques out to power consumers. Presumably they were generating to some other undisclosed contract price. Yet the AEMO RRP was drastically lowered across all states on the 22 July. See the Table “Average Daily Prices – Current Month”. Time to talk about re-nationalizing the coal fired generators at least. NemWatch for current generation. For large screen shot.
First time I have noticed negative price from Qld – minus $1,000 MW 3.20am 13 July 2017 – tick “QLD” on left and “5 Min” on right. Who knows why? Just more Govt madness. Not uncommon lately to get negative price periods in Tasmanian data. NEM Dispatch Overview always worth checking – see how Qld is the “anchorman” of our grid. NemWatch gives a generation snapshot.
Australian Energy Minister Josh Frydenberg states “In Queensland, over the first five months of this year, electricity consumers paid the highest wholesale prices in the NEM, 30 per cent above the average.”
That statement may be technically true but the chart of AEMO daily prices shows it to be misleading. In fact Qld prices were only notably higher than other States during two price spikes in January and February – for the more than four months post 24 Feb 2017 Qld prices have been subdued compared to the other four States in the Eastern Grid.
