M Group to support Britain’s clean energy future as part of National Grid’s Electricity Transmission Partnership

We’re pleased to announce that M Group Energy has been named as part of National Grid’s £8 billion Electricity Transmission Partnership.
This new partnership will see us working collaboratively with National Grid and other ETP delivery partners to deliver critical infrastructure to build a resilient grid, supporting Britain’s clean energy future.
As a regional delivery partner, we’ll have first refusal of future substation work in the pipeline within the South West and South Wales, meaning we will have the certainty to invest in local people, skills and innovation.
It also marks a major boost to National Grid’s ambitious RIIO-T3 investment plan, which proposes up to £35 billion investment in the transmission network in England and Wales over the five years to March 2031, including to build new substations or upgrade existing ones.
As part of the ETP, National Grid expects to award around £8 billion worth of substation construction work over the RIIO-T3 investment plan, covering multiple regions and around 130 projects.
Steve Convery, substations director at M Group Energy, said:
“We’re pleased to receive the appointment to the Electricity Transmission Partnership. This partnership will enable us to manage energy projects across South Wales and the South West in the coming years.
“We’re excited about this opportunity, and look forward to working closely with National Grid, customers, supply chain and associated stakeholders to successfully deliver these essential upgrades, working towards a clean energy future.”
Alice Delahunty, president of National Grid Electricity Transmission, said:
“Our Electricity Transmission Partnership marks a bold shift in how we deliver vital electricity infrastructure. By adopting a regional, long term approach, we’re giving our supply chain the certainty to invest in people, skills and innovation. It’s a key step in turning our RIIO-T3 investment ambitions into action and building a resilient grid to support Britain’s clean energy future.”
