Public consultation on the LFC block operational agreement and the methodology to determine the balancing capacity in the Elia LFC block


Elia organizes a public consultation of the “LFC block operational agreement” concerning the methodologies and rules for system operation. 

At the same time, Elia consults the “LFC Means” document. In this document, the methodology is specified which determines with which balancing services the required reserve capacity will be delivered


Today, October 4, 2019, Elia launches a public consultation of the stakeholders on the LFC block operational agreement and the LFC Means as described in the following documents:
  • The LFC block operational agreement specifies the dimensioning rules for Frequency Restoration Reserves or ‘FRR’ (also referred to as aFRR and mFRR and formerly to as secondary and tertiary reserves) and the methods to fulfill the obligations of load-frequency control in execution of article 228 of the Belgian Federal Grid Code. After approval by the CREG, the LFC block operational agreement will replace the previous version and will enter into force together with the Terms and Conditions applicable to Balance Service Providers for the mFRR Service (T&C BSP mFRR).
  • In line with Article 228 of the Federal Grid Code, the LFC Means specifies the methodology which determines with which balancing services the required reserve capacity for aFRR and mFRR will be delivered. This proposal introduces a daily dynamic dimensioning of the mFRR balancing capacity to be procured on daily basis which will enter into force at the same time as the T&C BSP mFRR.
In parallel with this consultation, Elia organizes a consultation on its proposals on the T&C BSP mFRR which will facilitate, amongst others, the daily procurement of mFRR balancing capacity.
It should be noted that only the "LFC Means" and the “request of amendment of the LFCBOA" are subject to consultation. The explanatory note of both documents, as well as the LFCBOA with track changes compared to the previous version, are published for information.



The stakeholders are given one month for providing their comments and suggestions. This consultation aims to receive any comments from market participants and relevant stakeholders regarding the consulted documents and the consultation period is set from Friday October 4 to Monday  November 4 2019.
