    On the GB grid, the "TV pickup" remains a real effect, in the middle of and and the end of popular TV programmes and sports events.
    And guess what: those spikes are predicted by the grid operators. So they are not "sudden" in the strict sense of the word.

    You could say a goal in soccer is unpredictable and during the slow motion repeats the wife goes into the kitchen and opens the fridge and 1 minute later hundred thousands of fridges start cooling. But then again: you have half a minute or even a minute time until that happens.

    A SmartMeter and SmartCharger from Siemens, obviously you need an internet connection, and a power company involved in using your SmartMeter/SmartCharger.

    That means it hasn't been done. I don't give a shit about research projects.
    If it was a 1000 cars around 2005, then most certainly there are far more now.

    and still isn't anything widely available to power my home from an EV traction battery despite it being technologically not all that challenging.
    This is for 90% of the world completely irrelevant. Either we have no power outages (Europe), or if there is one: you are in much deeper shit than just having no power (Asia).

    Give it a few more years and you can buy your power to local home adapter in the shops around you.

    Coal and some types of gas-fired plants simply cannot be fired up quickly enough to respond to sudden spikes in demand,
    That is not how the grid works.
    First of all it usually always has enough reserve that a (several!) failing power plant can be substituted by the rest of the others.
    Secondly, there are no sudden spikes in demand. Grid operators perfectly know when a spike is to be expected (both ways).
    Thirdly, there is a fleet of plants called "reserve power", and yes: they can be spun up in a matter of 30 seconds or less.
    Fourth: you underestimate the speed how coal or gas plants react to changing load.

    Finally: for solar power and wind power grid operators use "forecasts", aka "prognosis". They pretty well know how much power the grid will receive from solar/wind the next 4 - 8 quarter hours and plan their dispatchable plans around that.

    People expect their car to be ready to go when required, and even with a safety net of any discharge to the grid will not take their car's battery below (say) 75% charge, that's still a 25% variance in how far the car will be able to go without requiring a top-up.

    On the other hand, apparently so does the report you linked to. Which does not appear to be a peer-reviewed paper.
    Obviously not. It comes directly from the research institute. No idea if it ever will end up in a peer reviewed journal. Probably less than 1% of scientific research results get published in peer reviewed journals ... there are simply not enough journals, and usually you have to pay to be published. For university research that makes no sense at all.

  23. Yeah,
    and we have to take into account that we and the other solar system are moving, so we can not aim directly at it but where it will be in 40 years.

    That electricity was probably generated by burning fossil fuels, spending roughly 3.3W of heat per 1W of generated electricity.
    It is more a 2 : 1 ratio, depending how you define efficiency, as a thermal power plant usually runs a bit less than 45% efficiency.
