DCRP ER P28 Working Group

ER P28 – Planning Limits for Voltage Fluctuations Caused by Industrial, Commercial and Domestic Equipment in the United Kingdom

A DCRP working group has been established to undertake work to revise ER P28. Following a request (found here) issued 10 September 2014 for interested stakeholders to join the working group the working group has been finalised. The working group is made up of sitting members and corresponding members.

The first meeting of the working group took place on the 9 December 2014. Phase 1 Planning Phase was completed in February 2015.

Phase 2 Review Phase was completed on schedule. A report from the P28 Working Group was completed and issued to the Grid and Distribution Code Review Panels in February 2016 with recommended changes to P28 (see Reports below).

The Phase 3 Revision Phase commenced in September 2015 as planned. A final complete draft (Draft version 1) was issued to the P28 WG for comments on the 23 December 2016. Further details are contained in paper DCRP_15_02_09. A amended final draft (version 2) of P28 Issue 2 was issued to the P28 Working Group on 13 April 2017 for acceptance. The P28 Working Group convened on the 17 May 2017 agreed a list of amendments. Following subsequent comments an amended final draft (version 3) was approved by the P28 WG and sent to the ENA Energy Networks Futures Group (ENFG) on the 1 August 2017.

Following comments from the ENFG in September and October 2017 an amended final draft (version 3.4) of EREC P28 Issue 2 was accepted by the ENFG in November 2017.

The Distribution Code Review Panel (DCRP) has sanctioned the latest draft version of EREC P28 to proceed to public consultation. Public consultation will open on 5 January 2018 for four weeks. Final publication of P28 Issue 2 is expected in Q1 2018.
