Every year the CREG approves Elia's evaluation of primary, secondary and tertiary reserves to be sourced.
Volumes needs of balancing capacity
|Required total volumes for year 2019 [MW]||Required total volumes for year 2020 [MW]|
|Primary Frequency Control (0s - 30s)
R1 – symmetrical – 200mHz
|80 MW1||78 MW|
|Secondary Frequency Control (30s – 15min)
R2 – symmetrical
|145 MW||Value to be confirmed|
Tertiary Frequency Control (15min)
* min 314 MW R3 Standard
|Value to be confirmed2|
- For the first auction of january a volume of 81MW will be procured.
- Dynamic dimensioning when new design mFRR goes live.
Dynamic FRR needs and mFRR volumes
The table below shows the upward FRR needs and mFRR balancing capacity according to the new calculation method which will be used to determine the mFRR volumes to be procured as from the ‘go live’ of the new mFRR design. The results of the downward FRR needs are published ex post on trimestral basis as there is no procurement foreseen of downward mFRR balancing capacity.
