The increased influx of renewable energy sources into the European grid poses new challenges to the transmission system operators in the daily operation of the grid.

Operation starts on June 1st, 2012
Further enhancement for security of supply in Europe
The increased influx of renewable energy sources into the European grid poses new challenges to the transmission system operators in the daily operation of the grid. Despite this new situation the TSC partners aim at maintaining the high quality of security of supply in the region.
Another important step towards this goal has been reached with the operational start of the Trial Phase on MRAs on June 1st, 2012. Following discussions with representatives of the different National Regulatory Authorities (NRAs) cost recovery for activation of certain kinds of multilateral remedial actions will be ensured on a temporary basis.
The procedure will help the operational planners to propose multilateral remedial actions to resolve security violations in the case when already all other available single or bilateral remedial actions are exhausted. As a novelty planners can now order redispatch capacities from all TSC member states and not only neighboring countries. The terms and procedures for the activation of such multilateral remedial actions have been summarized in the Trial Phase Agreement on Multilateral Remedial Actions which has been signed by all partner TSOs. The first weeks of the Trial Phase on MRAs shall also serve as a period for obtaining more information about the successful implementation of such operational procedures and if necessary to adjust them.
This new procedure demonstrates the strong commitment of the TSC initiative to foster security of supply in Europe.
TSO Security Cooperation
The Transmission System Operator Security Cooperation (“TSC”) was launched in December 2008 as an initiative with a decentralized approach to foster regional European cooperation for system security in the countries concerned and in the whole of Europe. Its members are Austrian Power Grid, ?EPS (Czech Republic), 50Hertz Transmission, Amprion, TransnetBW, TenneT TSO (Germany), TenneT TSO (The Netherlands), PSE Operator (Poland), swissgrid (Switzerland), ELES (Slovenia), MAVIR (Hungary) and HEP OPS (Croatia). The involved TSOs set up the “TSO System Security Cooperation” with a permanent TSO Security Panel (group of security experts), new cooperation tools for Control Centres and a common IT platform CTDS for data exchange and performing common n-1 security assessments. TSC’s main goal is to ensure the overall system security of the European network, an area with 170 million citizens, and is open to the participation of other TSOs.
