Volumes needs

Volumes needs of balancing capacity

The table below shows the required volume for primary, secondary and tertiary reserves, approved by CREG. 

  Required total volumes for year 2020 [MW] 
Primary Frequency Control (0s - 30s)
   R1 – symmetrical – 200mHz
 78 MW
Secondary Frequency Control (30s – 15min)
   R2 – symmetrical
145 MW

Tertiary Frequency Control (15min)
R3 Standard + Flex


(1) min 314 MW mFRR Standard
(2) Dynamic dimensioning when new design mFRR goes live (cfr. under) with min(490 MW mFRR Standard, mFRR to be procured)

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.
