Batteries Can Store 10 Minutes Of Electricity Needs

May 24, 2022

By Paul Homewood


This came up on Octopus Energy when I entered my meter readings today:




I think we can safely rule out relying on battery storage then!

    Not to mention how dangerous batteries are, with all those fires and explosions! See this at about 62minutes:

    If you live in the ‘right’ part of the world it might be 20 minutes. Here’s hoping 😎

      This nonsense is everywhere and the ignorance displayed is extremely depressing. How can anyone be so ignorant (= lacking knowledge or awareness in general; uneducated or unsophisticated)?

      Today, fairly breezy in Derby, to replace gas we need three times as much wind than we have already. About 75GW wind. Yesterday it would have been double that.

      I think practically it would be difficult to bring a complaint to the Advertising Standards agency, as all of the statements are true, taken individually. It is the suggestion that is completely wrong, but what the public are misled continually by the media and elsewhere.

      I do not expect any of the ‘crusading’ media doing an expose however?

    Is that before or after the UK has added 20m heat pumps to displace natural gas plus millions of EVs to displace oil fuel?

    Perhaps an Octopus customer would ask Octopus’s founder & CEO Greg Jackson? @g__j

    That’s why Boris’s ‘Net Zero’ dream is such a car crash. Not a hope in hell’s chance of success.

      Hopefully Boris and his lady boss won’t be pulled from the wreckage?

    Indian heatwave gone, Spanish heatwave gone, what will the BBC do now? North central Russia looks promising, but might be a bit remote, ne’er mind, wait a few days, sure as eggs is eggs somewhere else will have a hot day!

      The recent US PGA golf in Tulsa, Oklahoma was interesting weatherwise when the north wind blew on Saturday causing the temperature to plunge. Cold weather affects you if you have suffered injuries which is why the late great Barry Sheene moved to sunny Australia. Having nearly lost his leg after crashing his car, Tiger Woods faded away on the Saturday so badly he withdrew.

      And I had to laugh at the article decrying the heat wave in Pakistan/northern India where it had the March-April temperature map next to the 1979-2022 average temperature map, with a carefully-drawn line showing the area of study that was clearly a darker red in the March-April map while completely excluding the area of Nepal and Tibet that was light to dark blue, denoting temperatures that were significantly lower than the remainder of the map area. After all, if you don’t cherry-pick your data to support your argument, then you can’t use it to whip up fears about “climate change” destroying our lives.

    Not much of a heatwave in my corner of Surrey. Patio thermometer is showing 60F at 2pm. looking ahead to the Heathfield agricultural show on Saturday, it will be a coat day as a 3pm peak of 63F is forecast. Much will depend on how much the sun breaks through and at least there is no wind chill. June arrives in a week….

      Just imagine how cold it would be without AGW! You’d need hat and gloves to match!

    This is misleading as it suggests that batteries could provide electricity demand for 10 minutes. But global electricity demand is currently around 4000 GW (back of an envelope estimate of 100 times UK average demand), and grid-connected batteries are probably around a thousand times less than that.

    Grid-connected batteries are nowhere near being able to meet demand even for ZERO minutes.

      Yes. Its a scam the battery owners know that they make much more money as ‘standby’ and never used except for very rare occasions in a localised sense

      • May 25, 2022 7:25 am


        I believe that they make very good money when capacity is short and hence wholesale prices very high.
        Being a cynic, I don’t believe that they are charged completely from renewable electricity, Why would you?

    I know that there are vast numbers of small but powerful batteries around, for model aircraft and similar high current applications – probably surpassing the storage capability of big battery farms and the entire world’s car battery collection.

    But I am surprised to hear the assertion that this complete storage capability could run the world for 10 minutes. I would have thought less than 1 minute….

    Yes but this is old technology. In the brave new world of green technology, needed for every aspects of green fantasies, battery capacity will increase a trillion fold whilst prices will drop to zero

    Surely batteries can be made from that new wonder material – “unobtainium” ??

      You have to be on ‘hopium’ to believe that.

    The statement is somewhat meaningless, keeping in mind that batteries are used say to supply power to your house when your electric supply is down, or to store power generated in excess of power consumption say from a wind mill farm or a solar collector farm. Also, keep in mind that power generating plants (gas/oil/coal fired, hydros and geothermal) do not store any electric power: all the power generated is consumed as it is generated.
    I live in an all electric house, and consume from 740 kwhr to 3700 kwhr per month, or about 1 to 5 kwhr per hour average. Therefore, a battery with a 5 kwhr capacity would provide power from 1 to 5
