Britain’s National Energy System Operator (NESO) has announced it is overhauling the grid connection system to prioritise viable power projects, targeting decarbonisation by 2030. This reform aims to eliminate grid bottlenecks caused by non-viable ‘zombie’ projects.

The reform replaces the previous -served system that had led to a large queue of projects seeking connection.

Under the new framework, NESO will fast-track projects ready to build with necessary planning permissions and alignment with national goals. NESO identified 132 GW as vital for the Clean Power 2030 goal and an additional 151 GW needed by 2035, plus prioritisation for 99 GW powering data centres.

Ed Miliband, Britain’s Energy Secretary, said that over 300 GW of non-aligned projects will now not proceed.

A spokesperson for NESO said: “We’re proactively managing the connections queue so customers whose projects are progressing at their contracted rate can connect to the transmission network as quickly as possible. This is being achieved by terminating contracted projects not progressing against agreed milestones to free-up space for projects which are.”
