On 14th September 2017, the EU regulation 2017/1485, also known as System Operation Guideline (SOGL), entered into force.

  • coordination actions aiming to reduce FRCE as defined in Article 152(14);
  • measures to reduce FRCE by requiring changes in the active power production or consumption of power generating modules and demand units in accordance with Article 152(16);
  • the FRR dimensioning rules in accordance with Article 157(1).
