The Wind Power Fraud the same the World over: South Africans Rumble the Rort

Wholly unreliable Stone Age power source, meets
‘flighty’, but trusty South African beasts of burden.

STT expects that our followers’ Spidey-Senses have probably picked up that we’ve been going harder than ever in our efforts to belt the patent nonsense of attempting to rely upon a wholly weather dependent power generation source – smashing the infantile ‘logic’ employed by wind power’s proponents to sell their third-rate-wares, has been the main thrust of every single post that we’ve lobbed into the enemy’s trenches this week.

Operating under the ‘if it’s doing them damage, then keep doing it’ approach to destroying the wind industry (and the parasites that depend upon it), here’s another little piece – this time from South Africa.

The engineer that penned it, Terry Mackenzie-hoy, draws on work by another energy market expert, Professor Philip Lloyd – that spells out in clear and simple terms the facts that STT has been banging on about this week – well … since we began, really.

Cape Town professor’s research picks holes in claims about wind energy

Professor Philip Lloyd works at the Energy Institute at the Cape Peninsula University of Technology. He recently sent me a copy of a paper he had written, entitled ‘An Assessment of the Impact of Wind Energy on Energy Supply’. The paper addresses a number of concerns that power system engineers have with wind energy. Putting aside the visual and noise impact of wind turbines (and bird and bat strike), there is the matter that wind energy is often referred to as being ‘nondispatchable’ – the output of a wind farm can go from maximum to near zero, and there is nothing that the grid operator can do.

To keep the power supply to the load going, wind turbines then have to be backed up by ‘spinning reserve’ in the form of a generator that can be brought on line, if necessary, in a few seconds. Spinning reserve in this context refers to gas turbines. It is well known that gas turbines run up very quickly and consume great quantities of hydrocarbon fuel. Thus, using a gas turbine to back up a wind turbine is hardly a combination which can be described as being green.

Another characteristic of wind turbines is that they have a load factor which is low, compared with other generation. ‘Load factor’ is the ratio of the energy supplied by the wind turbine divided by the total possible energy that could be supplied by the wind turbine. It has been widely claimed by wind turbine suppliers that this load factor can reach 50% – at least half the total installed capacity.

What Lloyd has done is to examine the power output of the UK grid. This information is available from the UK Gridwatch and shows, with five-minute updates, what energy is being supplied by nuclear, coal-fired, hydro, wind, gas turbine power stations (as I am writing this, Gridwatch records that 10% of the UK grid is being supplied by wind and a third is being supplied by gas turbine).

Lloyd examined the figures for a four-year period. He found that the number of shifts in wind power supply where the shift was greater than 200 MW and lasting longer than five minutes is increasing and went from 10 shifts in 2011 to 80 shifts in 2014. He also found that, while in the last five years a 20% load factor is attainable in the UK, it is unlikely that this will ever improve.

Further, the maximum production from Britain’s wind system is 55% to 60% of installed capacity. This is a vital piece of information because it allows developers and investors to understand exactly what financial model applies to wind power development. What’s more, the UK wind farm capacity is about 12 000 MW. The figures indicate that it is quite possible on some days for this entire capacity to be unavailable owing to a lack of wind.

Lloyd notes: “Clearly, while it is true that the wind always blows somewhere, there are times when that ‘somewhere’ is a very small region in a very large system.”

He adds: “The implications of this are that it is essential to increase the spinning reserve as the proportion of climate-dependent renewable energy feeding a grid increases. Moreover, the increase in spinning reserve should be proportionately greater than the increase in the renewable energy. As spinning reserve is more costly than other sources of energy, the costs can mount rapidly. This needs to be taken into account in planning the expansion of renewable sources of energy.”

It is very unlikely that Energy Minister Tina Joemat-Pettersson even grasps this concept distantly. However, it must be understood, and understood clearly, that this very important piece of research by Lloyd has shown us the following: no wind farm will ever operate at a load factor greater than 20%. The maximum production from any one system cannot exceed 60% of installed capacity. The faster one grows renewable energy, which is climate based, still faster must one grow spinning reserve in the form of gas turbines. This paper is a landmark publication by the professor. I take off my hat and I bow.

Professor Philip Lloyd: want to ‘rely’ on wind power?
Then expect to burn an ocean of gas.

    The madness of wind power, or lack thereof, should most definitely,at the least lead to a moratorium on any further progress.

    There is no reason not to.

    The world in which we live is not changing in a cause and effect way the climate change charlatans purport, or if it is as a serious consideration, cannot be of such immediacy that we should do anything but tread warily and be calm and thoughtful and not be confused by that which is an ongoing and evolutionary process.

    The reasons the climate charlatans are seeking outcomes with such urgency is simply that they know that we know, and the game is up.

    What I knew 4 years ago, and before STT and The Callous Wind came to be was miniscule.

    Today, I could, with many others write a paper, of intellectual respect and understanding, of the absolute scam that is the wind industry.

    In time this will be done, and there will be governments and public service (lack thereof) bodies that will be held in and with contempt. These parasites will, without doubt be scurrying as rats from a sinking ship.

    Unfortunately, I have, and many who read and participate in this site and others of a kindred spirit experienced the amoral and sociopathic nature of these people and their belief of invisibility and unaccountability. Make no mistake. You are neither.

    Their lack of ethics and inherent psychopathy are obvious and the likes of Simon Chapman et al, will eventually be held to account.

    And so today Bill Shorten delivers a policy that means building another 12,000 turbines needing 12,000 turbines worth of back up. Unbelievably, the comments by readers of Australia’s major newspapers think its a wonderful idea and are incredulous that there are some doubts about the proficiency of wind turbines and the obvious ‘fact’ that power prices ‘must’ decrease. Well Shorten clearly has the inner city masses worked out! Now, how does one get through to them? Very hard to bust religious beliefs, but try we must.

    11.30 am BST. Wind for whole of UK is 0.19 GW; Demand 37.55 GW. Wind 0.51% of total demand.

  6. Relying on wind energy
    As only fools would do,
    But the green mist is clearing
    Now in South Africa too.
