No power cut here. Think there was a temporary problem with 2 separate power sources - a power station in Cambridgeshire and a wind farm in the North Sea. Think it led to some outages in various parts of the country and affected things like rail journeys. A minor and rare blip.
Due to the loss of those two power sources the remaining sources were put under more load and their generators were consequentially slowed down. This in turn lead to a drop in mains frequency which is very tightly controlled throughout the whole of mainland UK. As a first measure, they simply cut off parts of the country and most of the rail network in order to reduce the load and gradually get the frequency up again before re-establishing the supply. Here's a more detailed explanation: http://mainsfrequency.uk/fm-home The current frequency can be seen here: http://mainsfrequency.uk/fm-meter Ralf -- Ralf R.
