Wind Power Collapsed During April

May 5, 2021

By Paul Homewood



UK Electricity Generation – April 2021


With last month being dominated by high pressure, wind power only contributed 11% of the UK’s generation, averaging 3.4 GW. Including embedded wind power, which is not included in these transmission figures, total wind power would be around 4.4 GW. For much of the month, wind power was much lower still, at times contributing less than 1 GW.

Current wind power capacity is 25 GW, so over April as a whole, wind has been running at 17% of capacity, about half its average level.

Even with the planned 40 GW of offshore wind capacity promised by 2030, wind power would still have only contributed about 9 GW during the month, whereas total generation has been over 31 GW.

Surely it should now be obvious that we cannot do without a reliable source of backup supply.




Meanwhile, the media continues to ignore the problem, and instead broadcast propaganda for the renewable industry:

    Strangely, that same press reporting 17.6GW output from wind turbines haven’t pointed out that at 11:00am on 13th April wind generation collapsed to just 0.199GW

      Ironic that the website from whence your image came is upbeat and thinks wind is wonderful!

    ‘Surely it should now be obvious that we cannot do without a reliable source of backup supply.’

    What is the business model for this ‘backup supply?’

      Some sums

      31-9GW leaves 22GW required. Multiply by 24×30, and we get 15.84 TWh. At $500/kWh, that would be $7.92 trillion in batteries. A non-starter, I think.

      ‘Demand management’ aka restrictions on access to power via pricing and/or contract terms.

        “Demand management” is euphemism for “blackouts.”

      Taxpayers cash! To stop the back-up generation going bankrupt due to the uneconomic operating conditions created by the government it must be subsidised so that it can step in when the unreliable generation only made possible by subsidies fails. Next time the Martians land they will consider instant mash potato to be quite sensible compared to our generation system.

    I am in my mid-70s and may – just – escape the devastating electricity shortages and rationing that is most definitely going to hit the UK as a result of Milliband’s idiotic climate change Act and the parallel failure of any government to institute any workable and timely electricity generation policy.
    I visited my MP to raise his awareness of this and ask him to take up the matter in parliament. He had no idea what I was talking about and absolutely no interest in pursuing the matter. The country and our children and future generations are doomed my the “here today, gone tomorrow” opportunists who allegedly represent us.

      The national debt is currently about £4.8 trillion, some £78,000 for every person in the UK.
      And we’re planning to throw away further trillions so that Boris can continue to indulge in virtue signalling. Utter madness.

        Its not, it’s around £2.5 trillion.

        Read the article.
        ‘The truth however is much worse, factoring in all liabilities including state and public sector pensions, the real national debt is closer to £4.8 trillion, some £78,000 for every person in the UK’.

    With unbelievable stupidity, the UK, not even afforded a referendum on the subject and without the freedom to even debate the lie, is embracing this ‘Climate Change’ tyranny which only helps China to reach its Global Domination agenda.
    The gullible West is outnumbered many times over by the populations in possession of ‘Common Sense’ in China, India and many other countries which don’t even believe in any of this childish AGW hypothesis.

    Gas reserves are a lot lower than last year, LNG just in time shipments are keeping us going, you can see the charts here

      They’ve been dipping into the linepack. Not enough LNG shipment. Apparently not able to ramp up pipeline supply. A lot more demand for elec gen than they had bargained for, plus extra heating too compared with normal seasonal demand. .

      Sounds like a good time to have a fleet of reliable coal fired power stations with coal in stock.

    To make matters worse! If we don’t build a UK alternative for the interconnects to the EU we will have a week hand when it comes to negotiating access for fishing when the waters revert to the UK and for any other changes we might like to make. The Channel Islands are being threatened with this now and the French parliament has openly debated this tactic.

      Two of our interconnectors – BritNed and IFA2 – are currently out of action anyway. Jersey has previous experience of being cut off from France due to cable failures, and it still has backup generation that is diesel and oil fired (steam). That will add to costs of course, but it means they probably get to avoid blackouts.

    Then we have this from the Guardian….. May 4th..
    ‘Blustery bank holiday helps windfarms set new clean energy record’

    • Ray Sanders permalink

      A typical article written by Jillian Ambrose who has the scientific capacity somewhere between a mushroom and an amoeba. I just loved the line “The blustery bank holiday produced a new wind power record as turbines generated just over 17.6GW of electricity for the first time in the middle of Monday afternoon, enough to run more than 3.5m kettles. ”
      I have no idea how much power Silly Jilly thinks an unspecified “kettle” uses (presumably but not necessarily an ELECTRIC kettle rather than a hob kettle) and neither, of course, does she largely because they don’t normally teach English Literature graduates basics like that.
      I emailed the Graun to point out how risible the article was but unsurprisingly they didn’t reply.

        “enough to run more than 3.5m kettles”

        A new metric!

        “17.6GW of electricity”

        What is that in Hiroshima bombs? [Gamecock’s preferred unit of measure for energy]

        The utterly dumb thing she doesn’t notice is that she highlights the problem – that this amazing amount happened at one instant. So great if 3.5 million of us turned on our kettles then but useless before and after.

        Where can I buy one of these 5kW kettles?

      The Timnes was no better on 5th May. The following was probably based on the same press release:
      “Blustery weather helped Britain’s wind turbines to generate a record 17.6 GWs .mid afternoon on Monday …….. . The record ,edging above the previous high of 17.5 Gw hit in february was set in the haf four before 3.30 pm when wind was the biggest source of electricity at 48.4 per cent of the mix etc etc .
      Paul, can you include the editors at The Guardian and The Timmes in your recipients list of the facts about the resiliance of wind energy and the cost penalty imposed on he consumers by the supply costs and compensation payments?

    The surge on Monday was quite dramatic.

    I posted on Jo Nova about this a while ago – I predicted the MSM would hail the success of the spike, and ignore the almost complete failure on more than 1 day in 3 over the last month.

    Sky news might have reported that, over the year, carbon dioxide intensity of the grid increased. The monthly chart shows the lack of wind very colourfully.

    Surely windfarms should only be allowed to supply power on a continuously available basis.They would then have the obligation to make arrangements for back up supply.

    • Phoenix44 permalink
      May 6, 2021 9:42 am

      The obvious solution. But that would require those in power recognising that wind was the problem rather than the solution.

    Oh dear, the wind has dropped back again to 3.36 GW. Thursday am.
    Not enough time (only 2 days) to recharge the batteries since the last wind drought.

    Here we go again.
    A public notice in the papers on the 28th April re;lated to a ” Proposed Application for a Development Consent for 2 more wind farms in the North Sea.
    The proposed generating capacity of each farm will be 100MW. .
    O intend to respond to the invitation to comment as a tax payer and legitimate consultee.
    Cn anyone remind me of the facts as regards the net output on an annualised basis of the windfarms commisioned thus far as apercetage of their claimed outpu capacity? Can someone remind me of the cost to the consumers based on guaranteed prices and the off-set compensation for refusing take take poer into the grid.. Apologies for the mistakes in the above. I can only see half of one line when drafting this.

      “On an annualised basis, you got as much electricity as you did before. So what are you griping about?”

      Wind power is GREAT!
