Climate Lies Threaten Civilization

Government funded climate insanity turned off the lights in South Australia this week, and threaten the same for all of Australia.

    Turnbull was all for renewables until this blackout – his jumping of the fence is an indication that the general population is becoming aware of the scam that is renewable energy since Turnbull will say whatever the polling indicates is popular.

    The situation is a total debacle but the renewables lobby and greentards are pushing back, saying more renewables would prevent the event since the storm was made so severe by CO2 induced climate change.

      The best thing is the rare leader of character and prudence who follows the will of informed citizenry.

      The second best thing is a shrewd politico who follows the will of informed citizenry.

      I don’t know where Turnbull exists on the continuum but he seems to know from where the wind blows.

      • Streetcred says:

        We can safely say that Turnbull, ex Goldman Sachs, is a popularist warmist who will say and do whatever it takes to get support for himself and his Banker cohorts. This is nothing more than lip-service to sceptics within the government.

    no, a severe storm turned the lights out. The power fail would have happened with any generation system…

    “23 towers in five locations, affecting three major power lines, were lying on the ground, ripped out by the storm.

    As Simon Emms from Electranet made clear on Thursday, when you take more than 700MW of generation out of the system in a matter of seconds, no grid that he knew of could have kept going”

    “Where the transmission lines, managed by ElectraNet, came down is south of Port Augusta. In May this year South Australia closed its last coal-power station at the port. If those coal-power stations were still operating, they still would have dropped offline and seen the cascading failure that tripped the generations. Having those thermal generators there wouldn’t have helped at all.”

      Your statement is false. The SA grid lacked sufficient inertia to maintain frequency. So most of the wind tripped off. The gas plant could not come on fast enough, the overload tripped the interconnectors, and the whole thing went down. The greenies are trying to spin it otherwise, but a lot of commenters at JONova where this has been dissected for two days are EEs with utility grid working experience. A simple look at the wind production plus voltage and frequency on the interconnector provides conclusive proof. The few storm related lost transmission pylons would have led only to a local blackout, not the whole province.

        AAA+ yup
        prior to wind dragging it down no matter what happened damages wise a section would fall out
        NOT ever the entire damned state
        I lived in SA for 50+yrs and remember the rolling strikes and the odd blackout on summer n winter fire or storm times
        not ever did the entire state go offline

      Getting your news from the Conversation or Renew, is like getting it from Pravda.

      The same ultra-far-left lies and propaganda.

      Suits your ideology though, doesn’t it Griff.

    • Mark M says:

      Observations show 40% renewable energy cannot stop a “unprecedented” one-in-50-year-event.
      How much % renewable energy is needed for South Australia to prevent it’s first drought?
      Dec 2015: Is drought the new normal for the once lush south-east of SA?

    • Analitik says:

      It is absolutely true that taking 700MW of generation out of the South Australian grid meant that demand was certain to outstrip supply. What is hidden in the official statements is that the pylon collapses should have resulted in blacked out “islands” while the rest of the grid stayed up. The remaining generation in South Australia was on the other end of the section of transmission lines that went down so it is not as if Adelaide had all it’s power pulled.

      You can read why the grid did collapse in my post at the end of this thread.

    Griff suggest you read this article:

    “True it was that lines were damaged in the mid-North around Port Augusta, but that doesn’t explain why the whole State’s supply went down. Grids are designed with with a level of redundancy, and to avoid complete collapses by isolating damaged sections, in order to keep the balance up and running.
    “For those truly interested in the cause, what appears in the graph above – care of Aneroid Energy – gives a clue as to the culprit.
    SA’s 18 wind farms have a combined (notional) capacity of 1,580MW.
    On 28 September (aka ‘Black Wednesday’), as the wind picked up, output surges by around 900MW, from a trifling 300MW (or 19% of installed capacity) to around 1,200MW.
    As we explain below, electricity grids were never designed to tolerate that kind of chaos, but it’s what occurs in the hour before the collapse that matters.”

    IOW the rapid fluctuations and sudden shut down of the wind turbines caused the grid collapse. The power lines down only caused local disruption.

    • Analitik says:

      That is not the cause

      If look at Wednesday’s wind generation at the Aneroid Energy site and isolate South Australia, you will see that all was going swimmingly with strong but not excessive output of around 70% capacity factor until the grid suddenly collapsed

      If you also check do the same for fossil fuels (you need to remove some Qld power stations that aren’t eliminated by the state checkbox), you will see the real issue is the very low amount of fossil fuel generation that was taking place at the time. The Ladbroke OCGTs were flat out with Hallett ready to ramp for coping with fluctuations but the only other thermal generators online were the Torrens B units so there was very little synchronous inertia available to stabilise the grid.

      Most wind turbines in Australia are either doubly fed or full converter so they are asynchronous in operation and provide zero synchronous inertia for grid stabilisation. There are models of asynchronous wind turbines which have circuitry that provide synthetic inertia characteristics over a few seconds (at the cost of extra expense and a relatively long recover period) but these have not been deployed in Australia,

      The indications are that the Heywood interconnector was lost, islanding the South Australian grid creating a non-credible event. With the high amount of wind production and low amount of synchronous inertia, it wouldn’t have taken much of a trip event to cascade down the whole grid as there would not have been much inertia to drive current through the trip so it could be isolated.

      Given the forecast bad weather, what should have been done was for the Torrens A units and Pelican Point CCGT, South Australia’s other remaining baseload generators, to also have been online as spinning reserve that afternoon. This would have provided as much synchronous inertia as was available to stabilise the grid against the trips and surges that are inevitable during wild weather. Then the trips would have been isolated by the circuit breakers as the generators would have been able to provide the current surge needed to trigger the breakers and there would have been blacked out islands rather than the whole grid going down.

      The pylons going down SHOULD have been a localised problem. The fact that the whole grid was blacked out shows the yet another limitation with renewables.
