Update from National Grid – Elstree Substation to Sundon Substation overhead electricity line refurbishment

National Grid has been refurbishing the existing 400kv overhead electricity line that runs between our Elstree to Sundon substations and passes through your parish.

We’ve now completed all phases of this work including reinstatement activity to remove our temporary trackway and Heras fencing, take down works sites and remove equipment.

Our work will ensure long-term energy security for southern England on both the high-voltage electricity transmission network, and the local distribution network supplying homes and businesses.

National Grid would like to thank local residents and businesses for their patience and understanding during these essential refurbishment works. Should you have any questions, please contact the team on: elstreetosundon@nationalgrid.com.
