GSR029: Review of Demand Connection Criteria to Align with EREC P2/7
What is being proposed
This modification is proposed to review the demand connection criteria in Section 3 of the NETS SQSS to resolve the discrepancies with EREC P2/7. This includes the review of the group demand definition and demand security contribution assumptions from embedded generation, demand side response, storage and active network management schemes

Timeline
Analysis
NESO proposes reviewing demand connection criteria in the transmission network security standards (NETS SQSS) to align with distribution network security standard EREC P2/7. The review covers how embedded generation, demand side response, storage and active network management contribute to demand security. The workgroup process has been running since June 2022 with next meeting scheduled for March 2026.
Why it matters
This attempts to reconcile inconsistencies between transmission and distribution security standards that create regulatory arbitrage opportunities. However, the three-year workgroup timeline suggests the technical complexity of defining equivalent security contributions across network levels remains unresolved.
