rota block disconnection information

In exceptional circumstances, should there be a severe shortage of electricity production in the UK, distribution areas may be required to disconnect electricity to customers for a set duration, on a rota basis.

The purpose of Rota Disconnection is to reduce the demand for electricity to the level of production that is available. This is achieved by dividing all the users of electricity into groups, called blocks, which are determined by your postcode. These blocks are then switched off, in turn on a rota, for minimum intervals of three hour periods. If the shortfall becomes more severe, more blocks are switched off resulting in more interruptions.

This action can only be taken when it is authorised by the Secretary of State for Trade and Industy. The entire electricity network will be required to follow any instruction given in these circumstances.

Note to help you interpret the Rota Disconnection Timetable:

Go to the Rota Power Cut Level Matrix for your Block. Each Block has a weekly schedule of 56 equal periods of 3 hours. The periods for disconnection will relate to a severity number which will be announced in the event of an emergency. The higher the severity, the greater the number of periods you will be disconnected.

For example: if the severity Level is 1 and you are in Block A you will only be cut off in the 3 periods where you see the number 1 i.e. 9 hours in total during the week. However, if the severity Level is 4 you will be disconnected in the periods where there is a 1, 2, 3 and 4.
