ACER adopts Decision on electricity coordinated security analysis

Friday, June 21, 2019


The Decision aims to impose more concrete, enforceable requirements on TSOs and Regional Security Coordinators with regard to their obligations to design and coordinate remedial action.

ACER published a Decision on the methodology for coordinating operational security analysis for all TSOs, based on the EU Regulation on System Operation in Electricity. The Decision will serve as a pan-European framework for regional proposals on operational security coordination for each capacity calculation region (CCR).

It covers harmonised rules to identify the elements of TSOs’ observability area and coordination of remedial actions inside a CCR and between CCRs.

While the methodology was originally developed by all TSOs, ACER has introduced some amendments to the proposal to improve its legal clarity, also imposing more “concrete and legally enforceable requirements” on TSOs and Regional Security Coordinators (RSCs) with regard to their obligations to design and coordinate remedial action.

The Decision also includes a requirement for TSOs to develop a probabilistic approach to risk assessment to handle the reliability and costs of operating the power system. It further defines the rules to deal with overlapping zones between CCRs.
