£39.5m Project To Modernise Belfast's Electricity Grid

A new £39.5 million project to modernise the electricity transmission grid in Greater Belfast has been launched.

The 'Energising Belfast' project will deliver a new high-capacity underground cable through Belfast city centre, as well as a new transformer at Castlereagh Main substation, increasing the reliability of the electricity system in Greater Belfast.

Northern Ireland's electricity transmission operator, SONI has hosted an event with the Northern Ireland Chamber of Commerce at Allstate's offices in Belfast city centre to mark the launch of the project.

Welcoming the launch Mike Brennan, Permanent Secretary of the Department for the Economy said: "Energising Belfast is significant in its potential to enable the economy in Belfast and wider Northern Ireland to grow with cleaner electricity and help to deliver the Northern Ireland Energy Strategy and the 10X Economic Strategy.

"It is helping in providing opportunity to deliver affordable clean electricity and to promote Northern Ireland as an attractive location for renewables investment. Our energy revolution will be based on Northern Ireland's innovation, engineering and IT expertise. Projects such as Energising Belfast allow our skills to flourish, build markets where we export those skills and innovations to the world and help enable a step change in the capacity in our electricity network."


Alan Campbell, Managing Director of SONI commented: "A thriving city centre is vital to the prosperity of Belfast City and the region. This project will prepare the transmission system, ensuring Belfast is equipped to avail of the economic growth opportunities, as Northern Ireland transitions to net zero.

"While there is currently no finalised route selected for all parts of the project, it will include a new high-capacity underground electricity cable, which will help to underpin future investment, as it strengthens security and consistency of supply for businesses. The project will also enable older sections of the transmission line to be replaced, paving the way for the future removal of some pylons in Greater Belfast.

"This project will future-proof the transmission system in Greater Belfast to ensure businesses have the secure electricity supply they need to expand in the near-term and into the future, supporting the economic and societal vision of the Belfast Region City Deal.

"Along with supporting the decarbonisation of heating and transport, it will also prepare the grid to facilitate greater levels of clean energy, helping Northern Ireland to deliver its climate ambition of at least 80% renewable electricity generation by 2030."

NIE Networks owns and manages the transmission and distribution network in Northern Ireland. 

Randal Gilbert, Network Assets Director, added: "While SONI will lead on the functional design and consenting of the project, NIE Networks will be responsible for the technical design, construction and delivery of this new high-capacity transmission network across the city. Assuming SONI obtain all the necessary consents within the planned timeframe, we anticipate beginning construction in 2024 however the first phases of this project will entail enabling works at existing substations before the city centre works commence. The project is estimated to last for three to four years.

"The energy system in Northern Ireland is at a transformational juncture. Our vision is to provide an electricity network that is safe and reliable, capable of facilitating a net zero carbon future and one that meets the longer term needs of our society. We're excited about the opportunities that lie ahead of us and the transformation of our energy sector over the coming years."
