Power Flow Control is a new technology that can push power off overloaded lines or pull power onto underused lines. With this new power-electronic technology, we are now able to make the existing network more efficient, without the need to build new infrastructure.

Installing this innovative equipment at our existing substation in South Shields will provide more consistent, real-time control over how that new energy is routed, supporting the ongoing need for renewable generation and capacity on the network and allow us to continue to provide access to the network for our customers.

South Shields substation works

This work will include the erection of two new compounds on land already owned by National Grid for the installation of this equipment, and for some other associated works including new fencing. The main construction work is due to start later this year, and we anticipate that works on site will complete in 2027.

As we continue to reduce our reliance on fossil fuels and increase clean energy generation, we’ll be using more electricity than ever. That means we’ll need a grid that’s able to carry all this extra electricity to wherever we might need it.

Installing Power Flow Control technology at our substation in South Shields will allow us to continue to provide the best electricity flow around the country.

Our normal working hours will be between 7:00am and 6:00pm Monday to Friday, and 8:00am and 4:00pm on Saturdays and Sundays, if any necessary work needs to be completed. Essential activities that require continuous working will take place occasionally outside of these hours. In this incidence, we will inform affected stakeholders accordingly.



  • February 2024 – Surveys and preparatory work is ongoing from this date

  • Autumn 2024 – The main construction work is expected to begin on site

  • Spring 2027 – Works anticipated to finish on site

Have your say

National Grid is committed to engaging with communities at every stage of the project. Our dedicated community relations team works with local residents, businesses and community groups to ensure our work causes as little disruption as possible. Prior to the beginning of the main works, we will be holding a local information on Tuesday 9 July 2024, between 3pm and 7pm at Bilton Hall (Taunton Avenue, Jarrow, NE32 3RT).

This will provide an opportunity for you to meet the project team, learn more about what we are proposing to do, as well as ask any questions you may have, and provide any feedback you would like to share with us.
