means a legal entity with a legal or contractual obligation to provide a service contributing to one or several measures of the system defence plan;

means the TSO appointed and responsible for managing the system frequency within a synchronised region or a synchronous area in order to restore system frequency back to the nominal frequency;

means the significant grid user for which special conditions apply for disconnection and re-energisation;

means the netted value of active power seen from a given point of the system, computed as (load — generation), generally expressed in kilowatts (kW) or megawatts (MW), at a given instant or averaged over any designated interval of time;

means reconnecting generation and load to energise the parts of the system that have been disconnected;

means all technical and organisational measures necessary for the restoration of the system back to normal state;

means a legal entity with a legal or contractual obligation to provide a service contributing to one or several measures of the restoration plan;

means synchronising and connecting again two synchronised regions at the resynchronisation point;

means the TSO appointed and responsible for the resynchronisation of two synchronised regions;

means the device used to connect two synchronised regions, usually a circuit breaker.

means the fraction of a synchronous area covered by interconnected TSOs with a common system frequency and which is not synchronised with the rest of the synchronous area;

means a strategy that requires the assistance of other TSOs to re-energise parts of the system of a TSO;
