 Public Rights of Way

As part of our construction planning, we're consulting with users of the Public Rights of Way tracks along the cable route, to ensure that any closures are communicated in a clear and helpful way. We've established a PRoW Liaison Group, and have been working with Parish Councils to raise awareness of the coming works.

If you would like to see how we're proposing to manage the temporary closures, please see the illustrations below. A detailed schedule of works will be shared before construction starts, and any closures will be detailed.

For more detailed information on proposed PRoW closures and diversions, please visit the PRoW page here.

If you would like to join the PRoW liaison group, please email rampion@eon.com with and expression of interest.

Update on Current Work

1

Work has finished on the cut and fill exercise of the substation. Works are now progressing onwards with the installation of the main equipment, as well as local mitigation planting. The Public Rights of Way have been diverted and are being maintain by the site contractors. In the coming months, planting of trees and shrubbery around the substation will take place. The two 400kV transformers were delivered to site in November and works continue with the installation of site equipment.

ABB has been granted consent to work every weekend between the 22nd April 2017 and the 30th June 2017 between the hours of 8am and 5pm to conduct some electrical installation activities within the footprint of the Twineham Substation. This will allow connection to National Grid’s Bolney 400kV substation. ABB has also been granted approval to work every other weekend from this 22nd April 2017 date to work inside the OFTO and GIS buildings to install equipment inside the buildings to facilitate the future connection to the Bolney National Grid subsation. This will involve no HGV movements out of hours and staff working on site will use a minibus service to reduce the number of trips to site. During these times, members of the public can call the 0800 2800 886 phone number to contact a member of the team if you wish to discuss anything regarding the works.

ABB has also been given consent to work on filling the super grid transformer at the Twineham Substation with oil for its future use between the 2nd May at 7pm through to Monday 8th May at 7am. The work involves a specialised lorry pumping oil through the transformer twice in one long continuous process, which will require works to take place overnight. This work is only expected to take roughly 72hrs, should be finished by Thursday evening and other previous activities have gone on without incident locally. It is fully expected impacts from these works will be minimal on local residents. Please note, a longer period of consent has been granted in case of any logistical or processing problems during the works, which are not expected.
