Contacting us about Connections Reform​ | National Energy System Operator

NESO·guidance·low·26 Feb 2026·source document

Summary

NESO publishes guidance on contacting them about connections reform, directing customers to use the connections portal for application-related enquiries. The portal has been upgraded to handle 99MB file uploads and allow case comment updates without requiring NESO responses first. Non-portal channels may result in delays or unprocessed requests.

Why it matters

This administrative guidance consolidates communication channels rather than changing substantive connection processes. The portal improvements reduce friction for developers managing applications, but the reform's core economic issues — queue management, cost allocation, and readiness assessment — remain unchanged.

Key facts

  • Portal supports file uploads up to 99MB per file
  • Customers can update case comments without waiting for NESO response
  • Non-portal enquiries may face delays or go unprocessed

Areas affected
