U.K. Electrical Demand High.

Tonight the demand needle is nearly in the amber section of the meter. Does that mean this?


"According the Gridwatch tag: The amber warning represents the demand level that cannot be reliably met by wood or fossil burning, or nuclear generation, but must be augmented by imports, or unreliable intermittent renewable energy. Note that coal, gas and nuclear are close to limits."

  • Well, it does mean that, sort of !

    There is in fact a little more leeway than the above suggests. Wind power though inherently very variable can in practice provide 1Gw reliably, it is often a great deal more than 1Gw (7.5 Gw right now) it is however very rare for wind power to drop below 1Gw at this time of year.

    Imports can also be relied upon to a degree, cables suffer damage and the converters break, but it is virtually unknown for ALL the import capacity to fail at the same time.
