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

 

 

 

Load-Frequency Control Block (LFC Block) is a part of a synchronous area or an entire synchronous area, physically demarcated by points of measurement at interconnectors to other LFC Blocks, consisting of one or more LFC Areas, operated by one or more Transmission System Operators (TSOs) fulfilling the obligations of a load-frequency control (Article 3(18) od the Network Code on System Operation - SOGL).

 

The LFC Block refers technically to the balancing zone, which defines the size of the network area for which the balancing capacities are being procured (Commission Staff Working Document accompanying the document Commission Regulation of 23.11.2017 establishing a guideline on electricity balancing {SWD(2017) 383 final} p. 3). 

 

It is also accentuated that the LFC Block is important as “this is the geographical area over which reserves (other than the fastest type) ought to be dimensioned by the SOGL” (The EU electricity network codes, Technical report, Leonardo Meeus, Tim Schittekatte, European University Institute, Badia Fiesolana, February 2018, p. 11).

 

The determination of the LFC Blocks must be proposed by all TSOs of a synchronous area four months after the entry into force of the SOGL (art. 141(2) of the SOGL).
