Load-Frequency Control Area (LFC Area)
European Union Electricity Market Glossary


Load-Frequency Control Area (LFC Area) means a part of a synchronous area or an entire synchronous area, physically demarcated by points of measurement of interconnectors to other LFC Areas, operated by one or more Transmission System Operators (TSOs) fulfilling the obligations of a LFC Area (Article 3(12) od the Network Code on System Operation).


Supporting Document for the Network Code on Electricity Balancing of 6 August 2014 says the LFC Area is in most cases equal to the TSOs' Responsibility Area.


The above document explains, furthermore, that from a functional point of view, the term LFC Area is related to load-frequency control, aiming at balancing the LFC Area in terms of frequency, including loads and generation.


Therefore, a LFC Area fulfils the following functions:


- Being responsible for the Frequency Containment Process;


- Being able to maintain power interchange at the scheduled value;


- Cooperating to restore Frequency to its set value following a perturbation;


- Being responsible for accounting inadvertent energy deviations within its territory.
