Media gem from 2009 – West Australian Govt backed Perth geothermal projects to generate electricity from steam

Geothermal mine to power University of WA – note the quote “…be used in the design of a desalination plant, which would utilize geothermal energy to create fresh water.” I wonder where we find this raging success 7 years later? Green Rock Energy GRK is mentioned in the above article – they were reconstituted as Black Rock Mining Limited asx code BKT and here is the full share price history. Green Rock Energy fell on tough times and changed into Black Rock Mining Limited about a year ago – April 2015 and at that time the new company moved into graphite exploration. Note the map of Hot Rock tenements still held by Black Rock Mining Limited. Some around Wellington Dam.

Port Augusta coal fired power station shuts today

An example of Govt delusion IMHO – ABC reports – Port Augusta’s coal-fired power station closes in South Australia – They should be OK until peak loads on Adelaide hot summer days – then they will be stretching their resources if wind is light in the late afternoons. Checkout Nemwatch. Amazing that a modern first world State puts its entire economy at the whim of the wind. I have a few articles on this issue. For Peter Bobroff’s site AusGrid

How secure will the South Australian electricity grid be when coal shuts down next month?

Media reports say Alinta will close their coal fired generation at Port Augusta in May 2016. SMH and ABC – Last month I blogged – Will South Australia walk the talk and close their coal fired electricity generation? Since then I have obtained 12 months of daily South Australia electricity data and on Adelaide hot summer days when wind is not stellar it looks difficult to meet demand without coal. NemWatch

Large version chart -I am looking for a period of 5 minute data to check this further. Thanks to Peter Bobroff from the grid.publicknowledge.com.au site for these data.

Tasmanian Government fined $54K by ACCC for false advertising renewable energy

About time somebody got pinged considering claims made by renewable energy advocates over more than a decade. At a time when Hydro is saddled with the Basslink failure – I bet behind scenes unprintable.
Momentum Energy ads falsely claimed power generated ‘from thin air and fresh water’, ACCC rules
Check the brilliant little NemWatch to see in real-time how much renewable energy is being generated State by coal burning State
Here is the ACCC media –
Momentum Energy pays penalties of $54,000 in relation to renewable energy advertising 21 Apr 2016

What exactly are the three NSW large scale solar power plants generating?

I have been saving NemWatch screenshots offline for a few months now to get a handle on what the three NSW large solar power plants actually produce out of their rated capacity of 211MW. Plants are at Nyngan 102MW & Broken Hill 53MW – and Moree 56MW. I made 69 readings, mostly in March (36). If there are more than one per half hour slot – then they are averaged.

AGL’s Nyngan and Broken Hill plants combined are expected to produce 359,000MWhours of electricity per year which equals 40.98MW on a 24/7 basis.

Will South Australia walk the talk and close their coal fired electricity generation?

Last October South Australia was talking big about closing their last coal fired power stations near Port Augusta in March 2016 – Alinta to shut SA coal mine, power plants early – we will see. What do readers think? This chart of daily generation shows they would have to work their gas fired units much harder if coal closed.

NemWatch lets you see real time generation sources but does not show imports and exports. Thanks to Peter Bobroff from the grid.publicknowledge.com.au site for these daily data which reveal much.

Tasmanian electricity crisis explained day by day

Thanks to Peter Bobroff from the grid.publicknowledge.com.au site for these daily data which reveal much.

The last day of Basslink transmissions was 20 Dec 2015. It is fascinating that the cable failed a few days after exports were started. What was the rationale behind the decision to sharply increase Hydro production 16-17th December to export to Victoria – at a time dam levels were low? After Basslink failed it took a month to ramp up gas. Will try and get intraday day data in the week up to the break. A week ago I posted – “Base Load power is now a myth” so say renewable energy enthusiasts
Checkout NemWatch for real time electricity generation in each State and see how often wind is near useless.

Tasmanian electricity crisis rolling along

The pre-Christmas 2015 failure of the Basslink cable from Victoria has thrown a googly into Tasmanian electricity supply. Most of their supply is from Hydro, the last two years rain has not been stellar and storage levels are under 17% now. They have gas supplies from Gippsland and have gas fired generators. Nemwatch gives real time snapshots of what each source is contributing. Wind has less capacity than gas – thats when the wind blows. The State Govt which owns the Hydro and most other generation – is importing 200 diesel units to help through and the unions want their share. Then they can always turn off industrial customers if they have to. Basslink is taking longer to repair than was first thought.

Wind power is useless across Australia today

Scanning news headlines I discovered that the fault in the BASSLINK cable has not been found yet so there will be delays to the repairs timetable requiring the Tasmanian Govt to order 200 diesel generators. Upshot is the cable repair ship has not pinned down the fault location yet. Anyway – that nudged me to check NEMWATCH for the first time this month and the result at 4pm AEST 12 Feb 2016 is below.

Wind across Australia generating only 470MW. How has this taxpayer subsidised economic monstrosity been foisted on Australia and continues to be expanded? Answer is a combination of – Green Lies – GreenLeft media – gullible politicians – voter apathy. There are many days when wind generation is very poor.

Breakthrough turning CO2 into a clean-burning formate fuel using partially oxidized atomic cobalt layers

This research by Chinese scientists in Hefei is reported in Nature – Partially oxidized atomic cobalt layers for carbon dioxide electroreduction to liquid fuel
and Popular Mechanics – Breakthrough Material Is a Better Way To Turn CO2 Into Clean-Burning Fuel.

Could a process such as this be a basis for making CCS (Carbon Capture & Storage) more worthwhile?
