Members are subject to limited liability for acts of good faith, except where there is evidence of negligence. Powers of the EBCC:  Powers of the EBCC are primarily concerned with Energy Balancing, Security, Cash Calls and authorisation of the Trading System Operator. It is in these areas that the EBCC must make the decision concerning terminations.

4. Credit Risk Management Energy Where a User becomes a party to the UNC they become responsible for the financial implications of balancing their daily gas flow and assume a share of the credit risk associated with other Users’ Energy Balancing activity. National Grid Gas plc is responsible for managing the Energy Balancing Regime. However, in accordance with UNC Section V, National Grid has discharged its responsibility for managing the activities of Section X of the UNC by appointing a Transporter Agency. Currently xoserve Limited are appointed as the Transporter Agency. They are vested with several powers in Section X. A list of these powers can be found below.

12. SoLR Timeline The timeline below represents only a very basic example of the time periods involved with a SoLR. Ofgem may give either 24 hours or 30 days notice to revoke a supplier licence, depending on the cause, and a SoLR may only be appointed after revocation. Although Ofgem advise that the SoLR should be appointed on the day of revocation they do not guarantee that this will be the case. Further, Ofgem cannot give a guarantee that they will automatically revoke a licence upon satisfaction of conditions laid out in schedule 2 of the licence.
