We are becoming a separate company

In April 2019, the Electricity System Operator is becoming a separate company within the National Grid Group. Find out more about what this change will mean.

Transmission charging methodology forum (TCMF) and CUSC Issues Steering Group (CISG)

The Transmission Charging Methodologies Forum (TCMF) is established under the Connection and Use of System Code (CUSC). The aim is to provide a forum for regular discussion between us and interested parties on the development of charging methodologies. We have combined this meeting with the CUSC Issues Steering Group. The CISG provides a place for interested parties can raise general issues with the CUSC that are not covered by any of the other groups established under the CUSC. 

All existing or prospective users of the connection and use of the CUSC are eligible to send one representative to forum meetings. In addition, representatives from other industry bodies such as Ofgem are invited. 

To find out more about how the meetings work, please consult the TCMF Terms of Reference document

If you would like to attend future TCMF meetings, please contact the CUSC team at [email protected]. The chair is appointed by National Grid and is currently Jon Wisdom, who can be contacted at [email protected].
