Balancing group
A balancing group contains a simple identifier, an indicator of gas type (for gas differentiation). Each TSO (Germany, Austria and Slovenia) can set a balancing group within a booking or bid. If the balancing group is required, it is not possible to bid without the balancing group.
A balancing group is an aggregation of exit and entry points that may serve for balancing the amounts of entry and exit capacity as well as to enable the execution of transactions for trading. It’s a way to structure the shipper company portfolio.
Portfolio code
A portfolio code provides the shipper a way to structure his portfolio. It is posted within a booking or a bid. Each TSO (Netherlands) can configure whether or not they ask for portfolio codes within a booking or bid.
(!) Keep in mind, a request to be part of a balancing group or portfolio code can be done only by contacting directly to the respective TSO.
