National Grid Electricity Distribution (NGED) is set to begin a major reinforcement project in Swansea designed to improve the reliability and capacity of the city’s power supply.
The scheme, which will see cables upgraded between Swansea Uplands and Townhill, aims to future-proof the network for growing electricity demand while strengthening supply resilience for homes and businesses.
Work is scheduled to begin the week commencing Monday 4 August 2025 and will continue for several months. Contractor Balfour Beatty will undertake excavation work along Townhill Road, including sections of the pavement and carriageway.
Ryan Davies, NGED’s Head of Operations for Swansea, said: “We are carrying out vital reinforcement work in Swansea to improve the resilience and reliability of the city’s electricity supply.
“These upgrades will help to meet new and future demand for electricity and allow us to restore power quickly if there are outages, supporting economic growth by ensuring a reliable energy supply for local businesses and the community.
“We recognise there’s never an ideal time for this type of work, but we have scheduled the start of work during the school holidays to minimise disruption as much as possible. We’d like to thank residents and motorists in Swansea for their patience while we complete the project.”
National Grid confirmed that every effort will be made to reduce disruption, but the works will require the use of heavy machinery and safety barriers. Access to properties will be maintained at all times, though residents may be asked to avoid parking in some areas while work is underway.
The upgrades form part of NGED’s wider programme of investment in South Wales’ electricity network to support the region’s growth and transition to cleaner energy sources.
