Cottam to Wymondley
Our overhead line running between Cottam Power Station in Nottinghamshire and Wymondley in Hertfordshire, has been in service since the mid-1960’s.
Over the next 2 years, we will be completing some essential refurbishment work to ensure that the line continues to provide a safe and reliable supply of electricity to homes and businesses in the area in the years to come.
The overhead line running between Cottam and Wymondley is approximately 170km in length. In the first phase of works, we will be replacing the wires that run between the pylons on the 90km stretch between Cottam and Ufford, near Peterborough. In 2023, we will complete the rest of the works, refurbishing the remainder of the overhead line between Peterborough and Wymondley.
The main refurbishment work for the second phase will take place from the Spring of 2023 and we expect all works on this phase to be complete with land reinstated by early November 2023.
Our experienced contractor, Morrison Energy Services will be carrying out the work and our working hours will be Monday to Friday, 7am-6pm with alternate weekend working.
Delay to phase four of the project
Our main works this year were due to take place between April and November 2023. However, due to constraints out of our control, we are not able to carry out phase four of the work at this time. This phase is between Eaton Socon substation and Wymondley substation.
We have applied to the system operator to secure an outage to complete the works. Once we have secured the dates and can resume work, we will notify all relevant stakeholders and update this web page.
How will these works affect me?
The refurbishment work will have no impact on power supplies in the area.
We aim to complete the works with minimal disruption to local communities. Most of the pylons are on farmland but where the pylons are closer to individual homes and businesses, we will notify the occupiers of those properties in advance.
