One of the major tasks of a Transmission System Operator is to maintain and secure the balance between energy produced and energy consumed within its control area, using balancing energy.
From 14 May 2013, APG and ELES (Slovenia’s Transmission System Operator) will strive to avoid counter activation of secondary reserve energy. As no transmission capacities are reserved for the exchange of balancing energy within this cooperation, free available capacities will be the limitation for the exchange. With the implementation of this cooperation costs for balancing energy can be significantly reduced in both countries.
The exchanged volumes (avoided activation of secondary reserve in APG’s control area) will be published from 14 May 2013, on the page “Secondary Control”, as 15-minute aggregates.
You can find a detailed description of the model on the page “Imbalance Netting Cooperation”.
