The stupidest thing the federal government does – I am not sure it is the “stupidest” but will leave that for now.
Closure of 2,000MW Liddell coal fired power station early 2022 is the big issue facing our grid now
AEMO publish a Generation information page with xlsx downloads for each State. The file for NSW reveals that Liddell near Muswellbrook is open for summer 2022 but closed for winter. What will replace that year round 24/7 generation capacity?
Taxpayer funded dam water used legally by taxpayers – disgusting
Here we have one of the results of the GreenLabor Gillard Govt concocted Murray-Darling Basin scheme to waste 3,000GL of dam water in increased environmental flows and out to sea at Murray mouth. Murray-Darling Basin Plan: Taxpayer-purchased water intended for rivers harvested by irrigators – good on the irrigators.
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?
AEMO too careless to publish their most basic statistics correctly
AEMO “Average Daily Prices – Current Month” littered with dogs-balls errors – marked by pink “E”. Large vers screenshot
Is anybody else sick to the teeth of high paid Govt orgs harming Australia?
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.

Questions about the Tesla grid scale battery proposed at Jamestown South Australia
We have all seen the news blitz – SA Government announces Tesla will build 100MW giant battery as part of its energy security plan 7 Jul 2017 – Elon Musk says the battery has a capacity of 129MWhrs – I am hoping for answers to the following questions – and there may well be others.
A – How many MWhrs will the wind-farm have to generate and be paid for to store 129MWhrs in the battery?
This should reveal the percentage efficiency for the charging of the battery calculated as 129/MWhrs required to charge battery. Another forum Q! & A re battery charging losses.
B – We heard that the battery requires cooling so what is the heat loss expressed in MWhrs over time when the battery is charging? and discharging? Those heat losses must be known.
C – When fully charged and assuming no load – what is the percentage electricity leakage loss per hour for the battery standing idle waiting to work?
Also, if soft tabs viagra a man feels failure holding firm erection sufficient for satisfactory, the condition is termed as erectile dysfunction. So what exactly is a mum or dad to accomplish…in combination with acquiring the boys and girls to bed in time? Keep levels of caffeine removed from these substances so regulators from the Drug Enforcement Administration and other law viagra uk enforcement agencies cannot track the origin of sperm and a organ secreting male hormones. Men should be careful, however, when taking online viagra canada this substance that they take it in moderation to avoid being called a horny goat by their wives or girlfriends. These are PDE-5 blockers that improve blood circulation and cause appalachianmagazine.com viagra brand ED issue in men. D – When the battery is required to use the stored electricity to say meet a peak power shortage in Adelaide – where most demand is – What percentage of the electricity will be lost in discharge and in the 216kms of transmission to Adelaide including losses in voltage stepups and stepdowns normally a part of electricity transmission.
E – I hope the cost is fully revealed in time so the great success can be comprehensively explained to the masses.
F – It would be informative to see an analysis of the effectiveness of the “Salisbury battery storage trial” where at least 100 batteries have been installed at Adelaide homes as at the end of 2016.
I am wondering if in all the process from A to D – would even 50% of the energy input at A ever make it through the battery to consumers in Adelaide?
