ACER publishes decisions based on EU
Regulation on System Operation in electricity (SOGL) - on the methodology for
coordinating operational security analysis (CSAM) for all Transmission System
Operators (TSOs) and the methodology for assessing the relevance of assets for
outage coordination (RAOCM).
The CSAM decision serve as a
pan-European frame for the regional proposals on operational security
coordination for each capacity calculation region (CCR). Among others, the CSAM
decision covers harmonised rules to identify the elements of TSO's
observability area and coordination of remedial actions inside a CCR and
between CCRs. RAOCM sets out harmonised rules for all synchronous areas and
describes in particular the influence computation method.
Both methodologies were originally
developed by all TSOs and submitted for approval to National Regulatory
Authorities (NRAs) before being referred to the Agency. The Agency introduced some
amendments to the all TSOs' proposals in order to improve its legal clarity.
Also, The Agency introduced some amendments
to the CSAM proposal in order to impose more specific and legally enforceable
requirements on TSOs and Regional Security Coordinators (RSCs) with regard to
their obligations to design and coordinate remedial actions. CSAM also includes
a requirement for TSOs to develop a probabilistic approach for risk assessment
- to handle the reliability and costs of operation of a power system - and
further defines the rules to deal with overlapping zones between CCRs as an
amendment to the methodology.
