Responsibility (control) area is a coherent part of the interconnected transmission system including interconnectors, operated by a single Transmission System Operator (TSO) with connected demand facilities or power generating modules, if any.
Regulation (EU) 2019/943 of the European Parliament and of the Council of 5 June 2019 on the internal market for electricity (recast) in Article 2(67) defines ‘control area’ as a coherent part of the interconnected system, operated by a single system operator and shall include connected physical loads and/or generation units if any.
There are three possibilities when it comes to interactions of the control areas with bidding zones:
1. the control area matching the bidding zone (most often, Poland, Belgium, etc.);
2. the control area split into several the bidding zones (for example Sweden);
3. several control areas forming one bidding zone (for example Germany).
Pursuant to the ENTSO-E Supporting Document for the Network Code on Operational Security of 24 September 2013 (2nd Edition Final) the term 'responsibility area' covers a different part of the system than the term LFC Area: the TSO is responsible for maintaining the (N-1)-Criterion of its own grid and all the interconnectors to adjacent TSOs.
The components comprising this network are together called responsibility area.
