Grid Code Specifications for Demand Connections

 

The aim of the European network codes is to guarantee equal and non-discriminatory conditions for competition on the internal energy market, to ensure system security and to create harmonised connection terms for grid connections. Nationally, the purpose of the Grid Code Specifications for Demand Connections is to ensure that

  • the connecting party’s electrical equipment withstands the voltage and frequency fluctuations occurring in the power system,
  • the connecting party’s electrical equipment does not disconnect from the grid due to frequency and voltage fluctuations,
  • while synchronised to the power system, the connecting party’s electrical equipment does not cause any adverse impacts to the other installations connected to the power system, and
  • the relevant network operator and Fingrid obtain the data on the connecting party’s electrical equipment, necessary in the planning of the power system and its operation and in the maintaining of system security.


The Specifications are based on the European Network Code (EU Commission Regulation 2016/1338), to which Fingrid has made national additions and clarifications.
