One of the first responsibilities of a TSO is the maintenance and warranty of the physical balance between electricity generation and consumption in their respective control areas by using balancing energy. Through the coordination of the activation
of balancing energy between different control areas, a substantial potential for
efficiency can be exploited.
One possibility to optimize balancing activations is to net the demand for balancing energy between several control areas. Through such Imbalance Netting Cooperations the activation of balancing energy can be significantly reduced and consequently the stability of the grid can be increased. The balancing costs of the involved partners can be correspondingly reduced.
The Imbalance Netting Cooperation (INC) with the Slovenian TSO ELES is in operation very successfully since mid-May of 2013. A further optimization is going to be put into operation from April 24th 2014, subject to successful completion of the internal testing, as APG starts to cooperate with the already operating International Grid Control Cooperation (IGCC). Within this cooperation Austria’s balancing
demand will be optimized with those of Belgium, the Czech Republic, Denmark, Germany, the Netherlands, and Switzerland.
In the framework of IGCC, no reservation of cross border capacities takes place. The cooperation is only allowed within the limits of the available capacities after the intraday trading.
The exchanged volumes (saved activation of balancing energy in APG’s control area) will be published after the launch of the cooperation on the APG-Homepage under the tab Secondary Control in a ¼ hour timeframe. A detailed description of the model can be found on the APG-Homepage under the following link:
