What’s been done so far in Snowdonia, what is coming up and what will happen if the project is taken forward.
A section of overhead lines in the Snowdonia National Park that crosses the Dwyryd Estuary near Porthmadog was identified as having a significant landscape and visual impact.
Winter 2014 – Autumn 2015
National Grid and independent landscape consultants undertook further technical work and considered the detailed input from local stakeholders in Gwynedd and the National Park. This enabled the project’s Stakeholder Advisory Group to prioritise the section of transmission line as one of four to be taken forward nationally in September 2015.
National Grid working with local partners established a Stakeholder Reference Group. The following organisations regularly attend these technical meetings:
- Gwynedd Archaeological Planning Service
- Gwynedd Council
- National Trust
- Natural Resources Wales
- Network Rail
- Snowdonia National Park Authority
Winter 2015 – Summer 2016
National Grid undertook environmental, transport and ecology surveys in the area around the line both within and outside the National Park boundary and engaging with technical stakeholders and members of the local community.
Autumn – Winter 2016
The VIP project’s Stakeholder Advisory Group reviewed the results of the environmental and engineering surveys, the stakeholder feedback and National Grid’s preferred options. The Group recommended that the project should proceed to further development work which will inform the preparation of a planning application.
2017 – 2018
Geotechnical surveys took place throughout 2017 and 2018; the results of which are helping us to develop detailed engineering designs.
In November and December 2018, we carried out a formal consultation, with three days of events in Penrhyndeudraeth and Talsarnau.
Stakeholders and members of the public in Penrhyndeudraeth and the surrounding towns and villages were invited to public consultation events to find out more about our plans. This consultation also provided an opportunity to submit formal feedback to our proposals.
2019 – 2020
We undertook a pre-application consultation, including an event in December at the Snowdonia National Park office in Penrhyndeudraeth, and submitted a planning application in March 2020 in respect of the tunnel head house sites at each end of the project, and associated infrastructure.
2021 – 2028
The current indicative programme is that, subject to all necessary negotiations, approvals and consents, on-site works will commence in 2021 with construction completion expected for 2028 when the pylons and overhead line will be taken down and permanently removed.
