National Grid names £1.2bn transmission partners

National Grid has named five partners for transmission upgrades nationwide. The £1.2bn package covers more than 1,000km of overhead line reconductoring.

IN Brief:

  • National Grid has appointed five partners for £1.2bn of overhead line reconductoring across England and Wales.
  • The initial programme covers more than 1,000km of transmission routes using higher-specification conductor materials.
  • The work forms part of the wider RIIO-T3 investment plan to strengthen electricity transmission capacity through 2031.

National Grid has appointed five delivery partners to carry out major overhead line upgrades across England and Wales under the next phase of its Electricity Transmission Partnership.

Balfour Beatty, M Group, Morgan Sindall Infrastructure, Murphy, and OTW have been allocated an initial £1.2bn of reconductoring work across more than 1,000km of routes. The programme will replace existing conductors with higher-specification materials, allowing lines to carry more electricity without building entirely new routes.

Alongside the immediate work packages, the programme sits within National Grid’s RIIO-T3 plan, which proposes £31bn of transmission investment through to 2031. Over that period, the company expects to upgrade around 3,500km of existing transmission lines, equivalent to roughly half of its network.
