David Bidstrup guest post. The cost of a fragile grid

On the 12th of March a substation fire that caused the shutdown of the Barker Inlet 210 MW gas power station in Adelaide. The interconnector with Victoria was under maintenance with only half capacity available and the combined output from the SA wind and solar stations fell to 2 percent of the rated capacity. Wholesale prices went through the roof with the maximum price per MWh reaching $14,348.00.

The six hour period between 6 p.m. and midnight cost $42,337,000.00 for 9,201 MWh giving an average cost of $4,596.00 per MWh. For the 18 hours prior to the interruption the average cost was $26.60 per MWh.  The total for the entire day was $42,958,000.00 so the 6 hour period accounted for 98.7% of the days cost and 86% of the month to date cost.

Looking at the month of March up to the end of the 14th, yields the following chart:

David Bidstrup The cost of a fragile grid

Note that the data is for each half hour period so for 14 days there are 672 data points on the X axis.

Overall the average wholesale price per MWh for March 1 to 14 incl. is $152.00 with a maximum of $14,348.00 and a minimum of -$628.00. All the other parasites have to add their cut before the public pay the bill.

    Where can i get in on this negative price!

    Imagine being paid to consume power because boffins have no way to turn solar panels off.

    Insane.

    If you think the grid is fragile now, wait until QLD starts closing coal fired power generators years ahead of schedule in order to meet their 50% renewables by 2030 goal.

    Pity we haven’t got a Government with the nous to fix this shit.
    I don’t know much about this, because to know, can cause cardiac arrest.
    However, when the price is $14,000 for a MWh, which is $14 for a KWh, and I happened to burn one KWh at that particular time, (ran the toaster for an hour) am I charged $14 plus addons?

  4. Herodotus says:

    A national disgrace.

  5. Roger says:

    Cynic,

    Short answer:

    No, your retailer absorbs the price spikes in accordance with the price specified your contract.

    @Mundi:

    Do they not have an on/off switch?

    Oh you need an updated ‘smart meter’ to allow for that function. Like the vaccine totally voluntary going forward.

  8. Cynic of A says:

    Roger:
    OK, but I assume the retailer gets the money from me in the first place, to “absorb” the loss? I mean, if the “avereage” cost is high, then the “average” price to the consumer must be high. What am I saying? Of course it is!
    Chris M:
    Yeah, I guess so. Didn’t think of that.

    They’re not. The ruinable carpet baggers are gaming the system to bankrupt thermal generators. They do that as they receive subsidies from LRET and VEET etc so still make money. As they’re the lowest bidder, they win. Thermal can’t do that so go broke.

    The cost of these subsidies in Victoriastan including SRET for rooftop solar, is now running at $0.025 per kwh.

    It’s racketeering pure and simple.

    This is obviously a “market failure”. The obvious solution is more government intervention.
    Well, that will be the story (if it ever gets any publicity at all).
    Renewable energy – where there’s more spin from the spivs than from the turbines.

  11. mundi says:

    Cynic,
    When it spikes to $14 per kWhour… this just means the monthly/yearly cost for the supplier goes up, and this is why power bills keep going up.

    The more unstable, the more expensive the average market cost ends up being, and the more reason they will say the average user retail price has to go up.

    What would be hilarious is: Imagine if every consumer had to pay the market rate. I think we would see some extremely interesting feedback to the government. Would any government last 5 minutes when it costs $3 to boil a jug of water?

    When it costs $5 in electricity just to cook dinner? The green scam would be over in a day.

    What other out come would you expect from a gullible, stupid Prime Minister who relies on lies about failed UN IPCC doomsday global warming?

    March 4, 2021: JOURNALIST: Prime Minister, we’re looking at [global warming] and all sorts of things here. You’re talking about more resources.
    Will those resources be taken out of the earth in a way that protects our environment and saves vulnerable species?

    PRIME MINISTER: If, I read recently a book, a friend of mine sent me a book by David Attenborough. I don’t know if you’ve read it. I’d encourage people to read it – I think it’s a very interesting read.

    Note to Scotty from Marketing; read this:

    ‘Our Planet’ film crew is still lying about walrus cliff deaths: here’s how we know

    “the claim by David Attenborough and the production crew of Netflix’s ‘Our Planet’ that the walruses they showed falling to their deaths were victims of global warming.

    Despite many statements to the press, the film crew have steadfastly refused to reveal precisely where and when they filmed the walrus deaths shown in this film in relation to the walrus deaths initiated by polar bears reported by The Siberian Times in the fall of 2017.”

    https://wattsupwiththat.com/2019/04/15/our-planet-film-crew-is-still-lying-about-walrus-cliff-deaths-heres-how-we-know/

    I advise Scotty from Marketing to not read UN 97% doomsday garbage and read science.

    I’m old enough to remember when Kevin Rudd told us it would cost us only $1 a year per person …

    “That is that they calculate that between now and about 2045 that you’d be looking at a total impact … in the vicinity of $45 per person over that period of time or something like $1 per person per year.”

    I always found it funny that SA (or more correctly Weatherdill) chose to blow up its nasty coal fired power station but never ever considered disconnecting from its nasty coal fired VIC interconnector. It was such a hypocritical, BS, self harming gesture. Its all about the virtue.

  16. Spurgeon Monkfish III says:

    An insane act of utter bastardry for which Weatherdill should be languishing in gaol.

    What a vile, spiteful and staggeringly ignorant idiot.

  17. Spurgeon Monkfish III says:

    the walruses they showed falling to their deaths were victims of global warming

    Ah yes, one of the great mysteries of our time. While it’s been established the poor ol’ walruses did indeed fall to their untimely deaths, was it the hungry li’l poleys or was it Rabbitboroughs’ own vainglorious film crew that prompted this act of mass Odobenine suicide?

  18. Speedbox says:

    …..the claim by David Attenborough and the production crew of Netflix’s ‘Our Planet’ that the walruses they showed falling to their deaths were victims of global warming.

    Yeah, it was utter bullshit.

    The walruses have been falling off that cliff long before David Attenborough arrived.
    The cliff is located nearby to Ryrkaypiy in Russia which is a very small village (population <1,000) in the far NE of the country. The average high temperature in the middle of summer is only about 8C and winter is typically -20C or less.

    Lovely walrus temperatures….and poley bears.

    According to local villagers, the bears are known to drive walrus off the cliff and subsequently feed on the carcasses later – and this has been occurring for as long as anyone can remember. And how do the walruses get atop the cliff? Well, local topography has a gradual incline from the shore, which is very narrow and rocky, up to the cliff top. The walruses shuffle up this incline followed (later) by the poley bears. Normally, the walruses shuffle down the same way when they are returning to the sea. The walruses go to the cliff top to moult and grow new hair, to whelp, to nurse young or just to rest.

    So, whilst this is a natural event, Attenborough's crew deserve a special mention. It is well known that walruses have very poor eyesight and can be easily startled, especially when they are on land. They are not built for agility in a rocky shore. Yet, Attenborough's crew were filming very nearby and at a minimum, were using drones overhead for additional footage. Some of the footage may have been by helicopter but in either case, this would be alarming to a walrus on land.

    Therefore, the walruses would have sensed the poley bears AND were being further unsettled by the scent of humans and strange noises (helicopter/drones) above them. To a near blind walrus, this would promote a terror.

    IMO Attenborough's inference that this was a all a result of climate change was dishonest and whilst the walrus deaths in falling off the cliff are a naturally occurring event, his crew have a degree of culpability.

    They also have quite a few diesel gensets around too – from after they destroyed the coal station. Your taxes at work…
