Answers to questions we’re often asked about SEGL2

Here you’ll find answers to some of the most frequently asked questions about the SEGL2 project.

We’ll keep these up-to-date as our work progresses and we hope they answer your questions about our work.

Who is National Grid and what do they do?

National Grid sits at the heart of Britain’s energy system, connecting millions of people and businesses to the energy they use every day. Our individual companies run the systems and infrastructure that deliver gas and electricity across the country.

What work is being proposed?

We are proposing the construction of a new High Voltage Direct Current (HVDC) Link from Peterhead in Aberdeenshire to Drax in North Yorkshire. The cables will travel most of their journeys under the North Sea before making landfall just south of Bridlington at Wilsthorpe, East Yorkshire.

SEGL2 will then run underground for approximately 68km and connect to the national grid at Drax. The link will provide extra network capability and strengthen the transmission network from northern Scotland to Yorkshire in England.

Why are you planning these projects?

The UK Government is committed to increasing the use of renewable energy and has a target to achieve net-zero greenhouse gas emission by 2045 in Scotland and 2050 in England and Wales.

The Government also has a target for the connection of 50GW of wind power by 2030. The proposed SEGL projects are essential to meet these commitments and create a cleaner, greener future.

Why are you building in Drax and East Yorkshire?

Drax was identified as the most appropriate location to connect SEGL2 to the existing network because that provides the network capability needed to deliver cleaner greener energy on to the rest of the country in the most optimum way. Many factors are very carefully considered including, balancing cost, benefit to the network and minimising infrastructure and impacts on people, places and the environment.

How long are the works expected to take?

If approved, we intended to begin construction on SEGL1 in 2024 and complete the works in 2029.

Will there be disruption in my area because of the proposed works?

The onshore cables between landfall and the converter stations will be buried below ground and any construction impacts will be temporary. After we complete our work, we will return the land to how we found it.

What are the hours of operation for the works?

Our normal working hours are typically 7am to 7pm Monday to Friday and 8am to 5pm on Saturdays.

Will the buried cables have any effect on my health?

Some people worry that EMFs may have negative health effects. We take these concerns seriously and want to keep the public, our contractors and employees safe.  We ensure all of our existing and proposed equipment, including those on this project, comply with independent safety guidelines set to protect us all against EMF exposure. After decades of research the weight of evidence is against there being any health risks of EMFs below the guideline limits.
