Contract and balancing groups

Balancing groups

Balancing groups are virtual energy accounts that allow market players to balance all feed-ins and withdrawals allocated to them and keep them aligned with schedules. The respective balancing group manager (BKV) is responsible for the balanced quarter-hourly current account of his or her balancing group. Balancing groups receive a unique Energy Identification Code (EIC). The EIC for (sub-)balancing groups is assigned by the BDEW or at the responsible LIO (Local Issu-ing Office) of the ENTSO-E. The standardised balancing group contract must be concluded before balancing groups can be established in TransnetBW's control area.

Registration of balancing groups

In the course of standardising these contracts, the German Federal Network Agency (BNetzA) has imposed the application of a uniform standardised balancing group contract on transmission grid operators with resolution BK6-06-013. This has been applicable to all new transactions in the control area of TransnetBW since 1 July 2011.

• Resolution BNetzA - BK6-06-013 PDF/138KB/DE
• standard Balance Group Contract (BNetzA) PDF / 338KB / DE

As of 1 June 2018, 12:00 a.m. every BKV receives a Y-EIC from the second balancing group to be established. This Y-EIC can only be used for national balancing group or scheduling transactions. This amendment affects Annexes 1 and 3 to the standardised balancing group contract.
