Negative electricity prices support case AEMO must be reformed

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.

NIWA “dryer than average” New Zealand rain Outlook looks under threat – again

The NZ climate prediction maestros look to have dropped another dodgy one – to my untrained eye anyway.
Stuff says – Live: Christchurch declares state of emergency, orders evacuation as floods rise – and the NZ Herald with hopeless front page – Winter storm chaos: What you need to know
If I read the COLA forecast right – more rain this coming week. Not long since – NIWA 3 month Outlook destroyed inside two weeks 11 Mar 2017

No Australian weather site has recorded a daily max of 50° this century

I had Lance staying overnight and this subject came up – me opining after watching too much ABC TV news for years – that some site must have hit the 50° in the last several years. When Lance pointed out on BoM pages that the last 50° plus was in 1998 – I felt somewhat conned. We searched Google and sure enough we found this article “The proof Australia is getting hotter” – which includes this rather specific claim – Quote “While Western Australia had a cooler than average year in 2016, some parts of the giant state did hit 50 degrees, Australia’s observation of such heat a first in two decades.” Well if 50 was hit it was not noticed in official BoM daily data. Screen saved. What an amazing lie – “fake news” indeed. Part of my conning was BoM news early in 2013 of the extension of temperature scales up into the 50’s. Oddly this neat animated map from Feb 2016 does not extend to cool temperatures around -10 that are quite common this winter. What other plus 50’s (122F) are there that the BoM should recognize?

Loony-toon negative wholesale electricity prices appear in AEMO Queensland data

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.

Minister Frydenberg oddly misleading about Queensland wholesale power prices

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.
