DCRP/25/02/PC: Annual Revision to the Distributed Generation Connection Guides

Distribution Code·regulation·medium·29 Mar 2026·source document

What is being proposed

The Distributed Generation Connection Guides (DG Guides) have undergone an annual revision in line with the requirements of the Distribution Code of Great Britain with a consultation due for release in March 2025. This modification proposes to collate the current guides into a single guidance document covering EREC G98 and EREC G99.DCRP/25/02/PC - Consultation Pack

Details

Analysis

The Distribution Code proposes consolidating EREC G98 and EREC G99 distributed generation connection guides into a single document. This annual revision follows Distribution Code requirements with consultation planned for March 2025. The change streamlines guidance for generators connecting at different scales rather than altering connection rules themselves.

Why it matters

Administrative consolidation that reduces complexity for developers but does not change connection costs, timescales, or technical requirements. The reform treats documentation structure rather than the underlying incentive problems in distribution connections.

  • Consultation due March 2025
