• TSC offers integrated output data which are useful for TSOs, as well as for other existing security initiatives (centralised or decentralised...)

• TSC is compatible with all organisational forms (among other TSOs) in Europe

• TSC can be extended, if there is an interest of other TS operators (even to other spheres of synchronous part of European grid)

TSC improves operational security of TSs in Europe

TSC -TSO Security Cooperation• Tool for closer cooperation between Transmission System Operators (TSOs) • It solves unfavourable operating situations (caused e.g. by high transit of

power from wind parks in Northern Germany).

These flows of power result from increased installed power generation capacities in wind power stations as well as from prices of power on spot markets (such prices of power are directly related to the volume of wind power generation)

Real-Time Awareness & Alarm System (RAAS) in Central Europe

• Global knowledge of situation in electricity systems and real-time information on main parameters which are available at individual dispatching centres

• RAAS provides warnings and alarms relating to grid conditions to all TSOs in the whole region in real time.
