SECURITY COORDINATION CENTRE

Security Coordination Centre SCC Ltd. Belgrade is the third established Regional Security Coordinator (RSC) in the Continental Europe region, and first in the region of South East Europe (SEE). Founders and owners of SCC are Transmission System Operators (TSOs) of Serbia (AD EMS) and Montenegro (CGES AD), as well as Independent System Operator (ISO) from Bosnia and Herzegovina (NOSBiH). Founded as a regional company in 2015, SCC’s main objective is to develop necessary services defined by ENTSO-E’s (European Network of Transmission System Operators for Electricity) Policy Paper “Future TSO Coordination for Europe” and by “Multilateral Agreement on Participation in Regional Security Coordination Initiatives” (shorter called MLA) in order to fulfil operational planning standards which are defined by European Network Codes/Guidelines. According to MLA, main services that RSCs should provide to TSOs are:

• validation and merging of Individual Grid Models (IGMs),
• coordinated security analysis (CSA) including remedial actions,
• coordinated capacity calculation (CCC),
• outage planning coordination (OPC) and
• short-term adequacy (STA) forecast.

So far, SCC is performing validation and merging of IGMs for day-ahead and intraday time horizons, as well as security analysis without remedial actions and coordinated outages planning in the SEE Maintenance Coordination group. Beside these daily processes, performed for its service users, SCC is participating in weekly operational processes: pan European STA calculation (process is organized on rotational basis among all RSCs) and regional OPC calculation (each RSC performs calculation for its region and then all potential incompatibilities are coordinated on weekly teleconference). Also, SCC engineers are contributing in development of mentioned functionalities within ENTSO-E’s Project Groups OPC and STA, together with other European RSCs and TSOs. Development of remedial actions functionality and automatic coordinated capacity calculation for 24 hours are in progress.

SCC has good operational and professional cooperation with other RSC’s as well: CORESO, TSCNET, Nordic and Baltic. Dynamic business surroundings and constant development mainly caused by changes in European regulative and requirements for being included in ENTSO-E association, and also specificities of transmission systems and national electricity markets in SEE region, represent additional challenges for future SCC development.
