DCRP/MP/23/01: - Engineering Report P28

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

What is being proposed

This Modification has been raised to assess the requirement to develop an Engineering Report, to provide supportive guidance on the technical application of specific areas of guidance provided in the current version of Engineering Recommendation P28 Issue 2.This Engineering Report is currently in early development, and will be Explanatory in nature. No change to EREC P28 is expected as part of this modification.

Details

Analysis

Distribution network operators assess whether to create explanatory guidance supporting Engineering Recommendation P28 Issue 2, which sets technical standards for distributed generation connections. The proposed Engineering Report would provide additional technical application guidance but would not change P28 itself. No timeline or specific technical areas are identified.

Why it matters

Administrative housekeeping that adds process without changing connection standards. Guidance on guidance creates additional documentation burden without addressing the underlying technical barriers that P28 creates for distributed generation.

Key facts

  • Covers Engineering Recommendation P28 Issue 2
  • Engineering Report would be explanatory only
  • No changes to EREC P28 expected
  • Early development stage
