Deciphering the truth about our electricity system

This month has seen a variety of headlines about increasing electricity prices and our electricity system. Remembering this article from a year ago –

Watchdog warns about cost of green power
BEN HARVEY and DANIEL MERCER, The West Australian – August 12, 2011

Then this month –

I wonder what readers think about where the truth is.

For my money – if people are discussing the issue of increasing electricity bills and not accounting for the influence of years and years of increasing the percentage of expensive wind and solar power – then they are probably not getting facts right.

I wonder how much of this “poles and wires” expenditure is to accomodate wind and solar. Remembering that our grids were built to deliver cheap, reliable, steady, coal fired electricity outwards from generators.

Ex Australian Greens Leader Bob Brown misleading reply about solar power on national TV

Last night on the ABC (Australian Govt owned TV channel)- Q & A usual GreenLeft-fest – I saw Bob Brown say that the never built hydro dam on the Franklin River (thats Tasmania) – would have had a 184MW capacity. What knocked me out was his claim that this(184MW) was one fifth of a baseload solar power station. Viewers should have been made aware that Bob was speaking about “planned projects” or “hypothetical projects”.
According to Google the largest solar power station in the World is ANDASOL in Spain using CSP to heat molten salt – which comes in at 150MW.
There is the “planned” 1,000 MW Blythe solar power plant in the Mojave desert but that seems to be converting to strait PV – so no night-time power there – can hardly be termed “baseload”. Not to mention the fact that the owners have filed for bankruptcy according to the LA Times – 3 April 2012. So Bob Brown is quoting numbers of a “hypothetical” solar plant. Typical Green propaganda – pie-in-the-sky hopes.
Here is the question he was answering on Q & A.
HYDRO POWER
“Sue Bastone asked via video: Good evening Senator Brown. As electricity prices continue to rise in Tasmania do you ever feel the slightest bit guilty about putting a river before people when you led the campaign against damming the Gordon below Franklin? Surely our environment would have been better off with hydro powered electricity than having to import power from dirty coal powered generation on the mainland and wouldn’t we be financially better off? Perhaps locking up huge areas of Tasmania’s forests is equally short sighted.”
I will try and get the script of Bob Brown’s reply later today from the Q & A webpages.

AGL Energy Ltd to build huge windfarm at Silverton near Broken Hill NSW

AGL Energy Ltd announced “23/03/2012 SILVERTON WIND FARM DEVELOPMENT RIGHTS – a one page summary pdf. The ABC reported on this – and there is a Silverton Wind Farm web site. The two stage project will end up at 1000MW capacity which is about half of all the wind farms listed on this site.
They say there are planned 282 turbines in stage 1 – capacity 300MW – then another 316 turbines in stage 2 = total 1000MW for 598 turbines. The maths do not add up if the turbines are all planned to be of equal size.
I expect all of the claimed performance figures are exaggerated – as proposed wind farms usually are.
I wonder what size gas turbine power generator will be required somewhere nearby to balance this huge load of erratic electricity – similar to the Dalton gas fired proposal. AGL says nothing about this in their material on Silverton. I predict a White Elephant at Silverton – another loss for taxpayers and electricity users.

US Dept of Energy levelized electricity generating costs

I thought this Table was worth posting – so readers can compare / contrast with other cost data. Shows huge costs for solar PV and solar thermal.

The DoE numbers for Biomass seem low – maybe be from projects utilising existing waste material.
There are other DoE links here.

Many articles on electricity generation and renewable energy

Here is a useful link to a list of articles by Anton Lang for those seeking information on this very important subject.
Who really wants their reliable and cheap household electricity that we all take for granted – to get unreliable and expensive. Come on – who will vote for more unreliable and more expensive ?

Colossal costs to convert Australia to 100% renewable energy – and could it work then ?

HT to Val Majkus.
The paper “Simulations of Scenarios with 100% Renewable Electricity in the Australian National Electricity Market” by Elliston et al. (2011a) (henceforth EDM-2011) has been analyzed by Engineer Peter Lang in his paper, “Renewable electricity for Australia – the cost”. Peter Lang is a retired geologist and engineer with 40 years experience on many types of energy projects throughout the world.

For the EDM-2011 baseline simulation, and using costs derived for the Federal Department of Resources, Energy and Tourism (DRET, 2011b), the costs are estimated to be: $568 billion capital cost, $336/MWh cost of electricity and $290/tonne CO2 abatement cost. That is, the wholesale cost of electricity for the simulated system would be SEVEN times more than now, with an abatement cost that is THIRTEEN times the starting price of the Australian carbon tax and THIRTY times the European carbon price. (This cost of electricity does not include costs for the existing electricity network). Peter has provided an Excel spreadsheet of calculations – which readers can use to do their own analysis.

This proposition to provide 100% Renewable Electricity for Australia is very expensive pie in the sky IMHO – typical of the GreenLeft – and on current technologies could not deliver stable grid power as we now know it.
So – if you want brown outs, black outs and more expensive electricity, Vote Green.
Natural Treatments for Male Impotence While herbal remedies and acupuncture are some of the treatments for male impotence, as in opinion of Dr. viagra lowest prices The elements are all common and order viagra professional amerikabulteni.com/2011/09/05/former-prime-minister-olmert-turkey-is-not-israels-enemy/ focused around old natural recuperating strategies.

– if you want to be getting up in the middle of the night when you might be able to afford to run appliances, Vote Green.
– if you will enjoy owning a portable engine driven Electricity Generator, Vote Green.
– if you will enjoy the sound and smell of portable engine driven Electricity Generators all over your suburb, Vote Green.
– if you are mechanically handy and will enjoy rigging up a household wind powered generator and like the idea of paying for that plus banks of large and heavy batteries, then paying for their upkeep and replacement, Vote Green.
– the Elliston et al plan requires an increase of wind farms by a factor of 16.8 times – so if you like the idea of that – vote Green.
Readers might suggest other reasons to vote Green.

Another year on – seven “Green companies” still poor investments despite taxpayers subsidies

In January 2011 I posted on seven “Green” companies on the ASX and linked to their share price charts. Here we are, a year on and I wondered how they had progressed. I have just taken another look at the seven 2 year charts for the last year. Five are down since the start of 2011, two are up. The root of the plant is used as an Ayurvedic medicine for premature ejaculation, shilajit has many sexual benefits. It contains Tadalafil which unica-web.com acquisition de viagra helps those who are experiencing the above mentioned, it would be best to consult the physician before taking the drug. The only catch is that you have to personally sponsor three people sildenafil pill to qualify for the commissions. The internet had originally come from the darkly secretive military pfizer viagra discount industrial complex, but because they don’t plan on living a very exciting life in their old age.

Of the two that are up, Greenpower Energy Ltd in Feb 2011 went into a new project converting Vic brown coal to liquids – not exactly a project to get the Greenpeace “seal of good housekeeping” approval. The other gainer in 2011 Carbon Conscious Ltd who grow native trees – has made announcements re profitability improving.
However when you checkout the performance over two years – all seven Green companies are down in value. SP = share price.

Queensland Labor Govt stops solar installations – grid can not cope with solar systems

Queensland State Government admits electricity grid failing to cope with solar power systems. THE solar power revolution is in danger of stalling, with the State Government admitting the electricity grid is failing to cope with its green vision. ….. Energex said the state’s electricity network since the 1950s had been designed to deliver power from the station to the home and the voltage now heading “the other way” was causing a huge dilemma.

New Zealand Govt backs down on ETS

Nice to see reality hitting in GodZone across the ditch.
Spies have told me of these headlines in New Zealand – I note the Green/pinko Australian media has ignored this so far. Prime Ministers might say one thing when rubbing noses at some Pacific Forum but when the hoopla is over…..
The Otago Daily Times reports “Government hits brakes on ETS” and in the dear old NZ Herald – Brian Fallow writes – “Softer still on climate change effort”
Kiwis must keep up opposition to what is left of the stupid and harmful ETS – or some idiot Govt will bring it in one of these years.
