What are you building?
We are building a new high-voltage electricity connection between Bridgwater and Seabank near Avonmouth. The new connection will be 57 km long – consisting of 48.5 km of overhead line and 8.5 km of underground cable through the Mendip Hills Area of Outstanding Natural Beauty (AONB).
As part of this connection, we will modify the existing overhead lines at Hinkley Point and Seabank, extend our substations at Seabank, and make some changes to the existing local electricity network owned by Western Power Distribution (WPD). Click here for further information.
Why do you need to build a new connection?
The connection is needed to make sure the country continues to have reliable supplies of electricity into the future. It will carry power from the new nuclear power station at Hinkley Point and other new sources of energy planned in the South West. National Grid has a signed connection agreement with EDF Energy and has a legal obligation to connect Hinkley Point C by 2024.
Why are you continuing construction works during the Covid-19 outbreak?
The Hinkley Connection Project is a key part of the national infrastructure. These are works that need to take place today to ensure the future running of the network. Together with our contractors, we are continuing to progress with the critical elements of the project in line with current Government guidance on construction activity. Read more
How are you keeping workers and communities safe during this time?
Work on site has been significantly reduced and we have introduced stringent site operating procedures to protect not just our workforce, but also their colleagues, their families and the communities in which they’re operating. We have, for example, restricted travel between our sites and removed skin contact entry systems, such as fingerprint scanners. To meet social distancing requirements, we are installing additional handwashing facilities and welfare cabins. Read more.
Have you got planning approval?
Yes, permission was granted on 19 January 2016. All documents relating to the decision can be found on the Planning Inspectorate website.
Where can I view technical plans and drawings?
The Planning Inspectorate published a number of approved plans and drawings on 19 October 2017. To view all documents, visit their website. Detailed construction and access plans can also be found here.
How long will it take to build?
The connection is made up of many different elements – like a series of interconnected projects that take place at different times over several years. We won’t be working across the whole route, all the time. We will work in different places at different times. In all, the connection and its associated infrastructure will take around eight years to build.
When are you starting work?
We started work at Churchill in North Somerset in June 2018.
The main construction of the new 400,000 volt electricity connection is expected to start in spring 2019, when we will start to build the 400,000 volt underground cable through the Mendip Hills Area of Outstanding Natural Beauty (AONB).
We have produced a high-level construction timeline which can be viewed here. A more detailed programme will be developed for each element of the project once contractors are appointed.
What is happening in my area?
How will I know when you are starting work in my area?
We have published a high-level construction programme which gives an indication of when works are due to start in each area of the project. It can be viewed here. More detailed information will be available once contractors are appointed.
We are committed to working closely with the local community and will keep you informed about what we are doing and when. We will be in touch with parish councils and local communities before work starts in each area.
Will you use the T-pylon along the route?
As a result of positive feedback during our consultation, we are using the T-pylon for the majority 81% (116 pylons) of the connection. The T-pylon is a third shorter than traditional pylons. For further information click here.
Will you fund local community initiatives?
We recognise our work may have an impact on local communities and our Community Grant Programme has been set up to support community organisations and charities in areas affected by our activities.
We welcome applications from projects run by charities and community groups that meet local needs by providing a range of social, economic and environmental benefits. Projects that meet our criteria can be awarded a grant of up to £20,000. More information about how to apply can be found here.
What are your working hours during construction?
Our agreed standard working hours are between 7am and 7pm Monday to Friday and 8am to 5pm on weekends.
Are you allowed to work on weekends or outside of these hours?
Most work will be carried out on weekdays. There may be occasions when we’ll need to work at weekends or outside the standard hours. These may include when we are working on a continuous process such as cable jointing, or if adverse weather or ground conditions cause delays, or to avoid traffic delays during the week, but there are restrictions to this.
