Accelerated Loss Of Mains Change Programme
We, alongside other Distribution Network Operators (DNOs) and Independent Distribution Network Operators (IDNOs), have joined forces with National Grid ESO on their 'Accelerated Loss of Mains (LoM) Change Programme'. The initiative to Futureproof generation assets and ensure compliance with new settings introduced under the Distribution Code.
The new requirements specify that the protection settings required for any new generation connecting to the network must now also be applied retrospectively to existing generation with loss of mains protection.
Loss of mains protection is used to prevent damage when issues occur on the electricity distribution network leading to the disconnection of generation unnecessarily. The effect of this, more often than not, happens when renewable generation is operating and the costs to manage any disruptions are paid for by the consumer and electricity industry. Updating loss of mains protection will therefore deliver a step change in how the electricity system can be operated allowing more low carbon power to be generated at a lower cost.
All owners of generation installed prior to February 2018, that currently complies with EREC G59, now need to comply with new settings required for the interface protection. This means owners will need to make changes to their protection settings, and have until 1 September 2022 to do so.
