My account is in the sixth comment.
Electricity prices at AEMO have spiked to over $250 per MWhr across Australia in the morning rush – Nemwatch shows wind through the “National Grid” (excl WA) is under 250MW. The Wind Energy site shows how this wind drought is now in its third day. None of this is news in the GreenLeft main-stream-meedja. Imagine the headlines if coal or gas fired generators were to fail like this? Write your MP’s and Senators – call for a moratorium on wind power – say you will vote to curtail the excesses of the MRET scheme and for sensible electricity prices.
On the weekend I noticed this error in the BoM rain map –
I thought come Monday they will correct this to 9.27mm. Here we are Tuesday and no such luck, the error has gone into their daily rain numbers – presumably to be discovered in checks at a later date, weeks months away. It has also gone into 3rd party sites like AWN –
there could be others. It puzzles me that an error as gross as this lives on for 3 days – surely a little robot algorithm could flag outliers way less than this. I thought it was topical in view of my call for an audit of Perth dam catchments rain data.
Electricity in South Australia $265 per MWhr as they fire up the diesel gensets. NemWatch for real-time generation in the states – AEMO for price & demand within the states – the differences shows SA must be importing over 500MW from Victorian brown coal generation. To see progress of the wind drought open the 3hr graph for August & check MW . Write your MP’s tell them of this and say you will be voting for a sensible power grid and moderate power bills. Drive home that these price spikes will keep recurring whenever the wind fades.
I have commented in four blogs on the stupid decision last year to lease the Port of Darwin to a Chinese company for 99 years. Now the Treasurer has knocked back further Chinese ownership of our electricity grid – let us do the obvious sensible thing and tell the Chinese we have changed our minds and Darwin Port is not for lease/sale. Lock the lawyers in a room till they come up with a formula. Nationalize it if we have to – just correct the monumental stupidity and lets move on. BTW does anybody know if Tony Abbott was the first PM to sight the proposal? Timing would suggest he must have known but I can not confirm that with Google.
“mem” has commented on information at the Melbourne Water web pages – inflows and storages. Using their csv file from the storage page I made this chart.
In March I blogged – Victorian Labor Govt moves to turn on the Wonthaggi seawater desalination plant – see my chart of Thomson Dam environmental flows –
I am short of time to add much until about 6 Sept – but can do quick blog housework.
From a Western Australian Govt report emailed me – Water Innovation. I have not located it online but could be related to this bumph.
Facts are that rainfall over the Perth-Peel urban areas, the catchment areas for the Gnangara and Jandakot Mounds, plus the Perth Hills water supply dams & and Wellington Dam catchments; would average over 7,000GL of free water from the sky per year.
This absolutely dwarfs any other water on their diagram as the Perth water supply totals about 4% of rain. The efforts of the WA Govt water authorities over decades have been to ignore the benefits of dam catchments management and to allow Perth dams to be effectively decommissioned, while taking Perth water supply to expensive seawater desalination. The Ancient Romans were far better water managers.
We need an audit of WA Govt dam catchments rain data.
Noticed this today on the way to morning peak demand – see the spike in all States at about 6am. The Wind Energy site shows a wind drought from yesterday midday. NemWatch. Easily understandable how low wind in South Australia can lead to price spikes when demand is high. But in the case of Vic, NSW and Qld with large coal and gas gen – the wind sector is too small to have much effect I would have thought. In the case of Tasmania obviously the Basslink cable lets Vic prices reflect to the south side of Bass St.
I am wondering if this spike is another sign that the fossil fuel generators are fed up with being used as suckers by the MRET scheme. I say good on them if that is the case.
Edit – 8am 6 Aug – Hiroshima Day – National wind drought now – to check on progress at Wind Energy – click the Tab to MW.
