The UK’s National Energy System Operator (NESO) has launched a public consultation on a new strategic framework to guide long-term planning for electricity, gas, and hydrogen transmission infrastructure across Britain.
The proposed Centralised Strategic Network Plan (CSNP) aims to deliver a coordinated, whole-system view of Britain’s transmission needs beyond 2030. It will outline a 25-year roadmap identifying where and when new infrastructure is required to support the country’s transition to net zero emissions by 2050.
“Our energy system is already changing to meet increasing demand, the government’s carbon budgets and the overriding need for security of supply and helping boost economic growth,” said Julian Leslie, NESO’s director of strategic energy planning.
“As the independent organisation at the centre of Britain’s energy system, taking this co-ordinated approach to infrastructure planning is vital – not only to help drive investment decisions, but also to ensure everyone has access to reliable, clean and affordable energy.”
The CSNP will incorporate both onshore and offshore electricity transmission networks, including cross-border interconnectors and offshore hybrid assets. It will also consider the role of hydrogen infrastructure, including the potential repurposing of existing gas transmission assets, which are not expected to expand but may be used to support the emerging hydrogen sector.
The plan will be reviewed every three years and is designed to balance economic, environmental, and social factors while supporting delivery of NESO’s Strategic Spatial Energy Plan (SSEP). NESO said it would use vector-specific analysis to determine system needs and outline delivery phases for required upgrades.
The five-week consultation period invites stakeholders from across the energy sector, local communities, and the public to provide feedback.
NESO is aiming to support a predicted doubling of electricity demand by mid-century through a more integrated approach to infrastructure planning.
