Powering up Belfast
Northern Christchurch, Belfast
In February 2021, we started a major project to increase the capacity and resilience of the power network to support future growth in northern Christchurch. We laid a new underground 66kV cable from our Marshland Zone substation on Prestons Road to a new substation under construction on Blakes Road in Belfast.
The work involved installing the new cable along a 4.1km stretch on Prestons, Marshland, Belfast and Blakes Roads. We worked in sections digging between a series of cable joint bays, installed reinforced concrete at the bottom of the trench then installed the new cable. The cable was then encased in thermal concrete before the trench was backfilled and the road surface repaired.
In July 2021 we completed a key stage of the work along Prestons Road. We installed a section of 66kV cable from the Marshland Zone substation through the intersection to Marshland Road. This was challenging as we had to reduce Prestons Road to one-way eastbound so that our crews could work safely. This meant our community had to detour around the worksite. We scheduled this work over the school holidays, put on extra crew and worked longer hours to finish as quickly as possible. The crews completed the work in three weeks, well ahead of schedule.
We have some final works to complete; joining sections of cable, but this will not affect traffic flows and will be completed by early 2022.
Thank you to the local community for their patience and understanding while we completed these essential works.
