Standing groups

Standing groups give industry participants the opportunity to discuss issues relating to electricity codes in further detail. These issues may be relevant to one or more of the codes.

Balancing services standing group (BSSG)

The balancing services standing group (BSSG) reviews the contractual arrangements for the procurement of balancing services in the balancing and settlement code (BSC).

The group considers potential developments to the provision of balancing services regarding:

  • procurement;
  • charging principles and contracting; and
  • contracting.

Grid code development forum (GCDF)

The grid code development forum (GCDF) facilitates technical discussion of grid code-related issues between us and interested industry participants. Here you will find the proposals for this new forum and details related to forthcoming meetings. 

To align the approaches between the grid code review panel and workgroups, the grid code development forum will be aligned to take place on a single day.

Past standing groups

CUSC Issues Standing Group (CISG)

We set up the CUSC Issues Standing Group (CISG) under the governance of the CUSC Panel. There are a number of other standing groups under the CUSC such as the Transmission Charging Methodologies Forum (TCMF); Governance Standing Group (GSG); Balancing Services Standing Group and the Commercial Balancing Services Group (CBSG).  

The objective of the CISG was to provide a forum where interested parties can raise general issues with the CUSC that are not covered by any of the other groups established under the CUSC. These issues could cover changes, for example, to general rights and obligations, User Commitment (pre and post connection liabilities and securities), general credit and security requirements and cross-code issues affecting the CUSC.  The Standing Group's aim was to consider and develop well-formed CUSC Modification Proposals to be taken forward by individual CUSC parties or by National Grid, and to coordinate and time proposals so that all industry parties were better able to resource CUSC workgroups. The intention was to be to run this group adjacent to TCMF to minimise travel for those who would attend both meetings. 

The actions of this Standing Group in no way restricted the right of an individual CUSC party to raise a CUSC modification proposal at any time in accordance with the rules outlined in the CUSC. 

The Terms of Reference and material discussed are provided here.

Cross Codes Electricity Forum (CCEF)

We ran this forum in partnership with Elexon and ElectraLink. We gave four reasons for attendance.

Reduce your resource burden: Multiple codes, multiple changes. Monitoring what’s going on takes time and effort. We’ll take the work out of keeping up with code changes. Come to our Cross-Codes Electricity Forum and experience a “one-stop shop” for BSC, CUSC, Grid Code and DCUSA change information. We’ll tell you what’s happening, what’s about to happen and why. Best of all, it’s free. And if you can’t afford to travel, you don’t need to leave your desk. Use our webinar to see and hear the presentations and ask us questions.

See the wood, not the trees: No jargon, no pages of detail. Just the key information you need now, in plain English. Go straight to the heart of the matter and learn where things fit into the bigger picture. Learn quickly what impacts you.

Get your questions answered: Got a burning question about a change? Confused by the change process? Ask us anything you like in an informal, face-to-face environment.

Know how, when and why to get involved: Learn about forthcoming and current consultations, and why your views matter.

The forum was held at ELEXON's offices in London every other month.  For more information, including presentations from previous forums and meeting dates, and to register your interest, please see the Elexon website.

European Code Coordination Application Forum (ECCAF)

European Code Coordination Application Forum (ECCAF) was a Standing Group of the GB Codes Panels coordinating the application of European Network Code Requirements to GB Codes.   ECCAF was replaced in 2015 by the Joint European Stakeholder Group.  

Following a process launched by DECC and Ofgem in January 2015, it was decided to merge ECCAF, the Joint European Standing Group and the DECC-Ofgem Stakeholder Group into one new forum to cover all European Electricity Stakeholder Engagement called the Joint European Stakeholder Group

The material relating to ECCAF will remain here for present.  

Any queries should be directed to [email protected].

The purpose of ECCAF was to provide a forum for discussion of matters relating to the coordination of efficient application of ENCs to the GB Codes and to provide advice to the GB Code Panels on these matters. ECCAF was established as joint standing group of the BSC, CUSC, Grid Code, STC, SQSS, D-Code and DCUSA panels.

Joint European Standing Group (JESG)

The JESG was replaced by the Joint European Stakeholder Group in 2015. Following a process launched by DECC and Ofgem in January 2015, it has been decided to merge ECCAF, the Joint European Standing Group and the DECC-Ofgem Stakeholder Group into one new forum to cover all European Electricity Stakeholder Engagement.  The new group will be known as the Joint European Stakeholder Group. Details of the proposal can be found here. 

The material relating to the former Joint European Standing Group will remain here for present.
