UK grid connections reform mishandled, Ofgem finds

Ofgem has published its assessment of NESO's handling of the Great Britain grid connections queue reform, and the verdict is mixed. The regulator identified missed deadlines, inaccurate connection offers sent to developers, inadequate engagement with project developers, and unresolved digitalisation issues. All four problems sit in the same reform programme meant to clear a years-long backlog that has slowed renewable and storage deployment across the GB zone.

Despite those failures, Ofgem stopped short of an overall negative rating. NESO met or exceeded expectations in seven of the eight performance obligations assessed, earning a headline grade of "good performance". The single obligation where NESO fell short was not named in the pv magazine report, but the combination of inaccurate offers and poor developer communication points squarely at the operational execution of the queue remediation process.

For developers and asset managers active in the GB zone, inaccurate connection offers carry direct commercial consequences: projects sized or financed on incorrect assumptions face renegotiation risk and schedule slippage. Ofgem's findings will feed into ongoing discussions about NESO's accountability framework and whether the current performance obligation structure is tight enough to protect developers through future queue reforms.
