ENA welcomes £20bn of early investment in onshore transmission networks

15 December 2022


Ofgem have announced 26 strategic electricity transmission reinforcements through the regulator’s Accelerated Strategic Transmission Investment (ASTI) framework, targeted at unlocking the government’s 2030 50GW offshore wind target.

Ross Easton, Director of External Affairs for Energy Networks Association (ENA), which represents the UK’s energy network operators said:

“The network reinforcements announced today are another positive step in the transformation underway in the UK’s energy system. Projects like these are unlocking billions of pounds in investment and economic growth right across the country, keeping the UK at the forefront of global offshore wind development. All networks will keep working closely with Ofgem, government and the wider industry to make sure that we can unlock strategic investment in an energy system that’s fit for 2050.”

Notes to editor

  • The Accelerated Strategic Transmission Investment (ASTI) framework will initially apply to around £20bn of onshore transmission network investment across 26 projects.
  • These projects will be delivered by the three transmission operators: National Grid, Scottish Power Energy Networks and SSE Networks
  • ASTI projects have a streamlined regulatory assessment process to provide earlier approvals and quicker delivery
  • If all ASTI projects are delivered by their optimal delivery dates, we expect consumers will see a net benefit of up to £2.1bn
