U.K. Electrical Demand High.

Zoomup
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."

    I think you are being over optomistic Mike. Switching off Industrial customers is a big deal, and I know because I used to work for one. They will not do it until every one is sure that our backup generators had the full load and were stable, phased and happy. The cost to them if there was a problem was very high because you could pretty much write off a days production and perhaps another day to fix the problems. In fact we used to run on diesel every afternoon in parallel with the mains anyway because the voltage was usually low otherwise. In the amber region there is a big risk of grid failure if a station drops out, or anything happens to the supergrid like a cable breakage due to an aircraft accident. The risk may seem small, but a 5 GW change would probably be sufficient. The weather is quite good at the moment but if there was a problem and we had some more snow the situation could easily get out of control. We need a great deal more nuclear to get the situation under control, but that is probably 20 years away. Welcome to green Britain.
