- divisibility
means the possibility for a TSO to use only part of the balancing energy bids or balancing capacity bids offered by the balancing service provider, either in terms of power activation or time duration;
- exchange of balancing capacity
means the provision of balancing capacity to a TSO in a different scheduling area than the one in which the procured balancing service provider is connected;
- exchange of balancing energy

- exchange of balancing services
means either or both exchange of balancing energy and exchange of balancing capacity;
- full activation time
means the period between the activation request by the connecting TSO in case of TSO-TSO model or by the contracting TSO in case of TSO-BSP model and the corresponding full delivery of the concerned product;
- imbalance
means an energy volume calculated for a balance responsible party and representing the difference between the allocated volume attributed to that balance responsible party and the final position of that balance responsible party, including any imbalance adjustment applied to that balance responsible party, within a given imbalance settlement period;
- imbalance adjustment
means an energy volume representing the balancing energy from a balancing service provider and applied by the connecting TSO for an imbalance settlement period to the concerned balance responsible parties, used for the calculation of the imbalance of these balance responsible parties;
- imbalance area
means the area in which an imbalance is calculated;
- imbalance netting process function
means the role to operate the algorithm applied for operating the imbalance netting process;

means the price, be it positive, zero or negative, in each imbalance settlement period for an imbalance in each direction;
- imbalance price area
means the area for the calculation of an imbalance price;
- imbalance settlement
means a financial settlement mechanism for charging or paying balance responsible parties for their imbalances;
- imbalance settlement period
means the time unit for which balance responsible parties' imbalance is calculated;
- integrated scheduling process
means an iterative process that uses at least integrated scheduling process bids that contain commercial data, complex technical data of individual power generating facilities or demand facilities and explicitly includes the start-up characteristics, the latest control area adequacy analysis and the operational security limits as an input to the process;
- integrated scheduling process gate closure time
means the point in time when the submission or the update of integrated scheduling process bids is no longer permitted for the given iterations of the integrated scheduling process;

- preparation period
means the period between the request by the connecting TSO in case of TSO-TSO model or by the contracting TSO in case of TSO-BSP model and the start of the ramping period;
- requesting TSO
means the TSO that requests the delivery of balancing energy.
- self-dispatching model
means a scheduling and dispatching model where the generation schedules and consumption schedules as well as dispatching of power generating facilities and demand facilities are determined by the scheduling agents of those facilities;
