Loss of Mains
Distribution Network Owners and National Grid ESO are teaming up through the accelerated loss of mains change programme to accelerate compliance with new requirements in the Distribution Code. The new requirements specify that the current protection settings required for any new generation connecting to the network must now also be applied retrospectively to all existing generation with loss of mains protection.
Loss of mains protection is used to stop any damage when problems occur on the electricity distribution network. Methods used in the past can disconnect generation when it is not necessary to do so. The effect of this more often than not happens when more renewable generation is running and the costs of trying to stop any disruptions are paid for by the consumer and electricity industry. Changing loss of mains protection will therefore deliver a step change in how the electricity system can be operated and will allow more low carbon power to flow at lower cost.
