Activated volumes and prices 1'
Elia publishes cumulative volumes and prices per product of the activated balancing energy per minute
Cumulative activated volumes and prices per minute
The cumulative volume and price per minute are both indicated for every product category (if the product was actually used). Only regulation-related measures requested by Elia with a view to offsetting imbalances in the control area are included.
The prices given on this page are:
- the cumulative highest price calculated by Elia for the minute in the quarter-hour in question in the case of upward regulation;
- the cumulative lowest price calculated by Elia for the minute in the quarter-hour in question in the case of downward regulation.
Time interval for publication of data
All published values are non-validated values and can therefore only be used for information purposes.
Legend
-
QuarterStart and end time of the corresponding quarter hour.
-
Minute
The minute at the end of which the calculation has been performed.
Example: “11:49” means that all events which occurred between 11:45:00.00 (hh:mm:ss) until 11:49:59.99 have been taken into account to compute the estimation of the data related to the quarter hour 11h45-12h00
-
Quality Status
Indication on the reliability of the data
The possible values are the following:
- Non-validated (default): the published data are likely but have not been validated by an operator
- Data issue: the systems have detected a potential issue in the calculation and publication flow
Important remark: the reference for the imbalance settlement are the 15-minute data
-
NRV
Net Regulation Volume
The net regulation volume is calculated using the difference between the sum of the volumes of all upward regulations and the sum of the volumes of all downward regulations requested by Elia. The values published at a given minute are computed taking into account the average of all the activations requested by Elia between the start of the quarter hour and the end of the considered minute.
-
GDV
Gross Downward Activated Volume
Sum of all downward activated reserves. The values published at a given minute are computed taking into account the average of all the activations requested by Elia between the start of the quarter hour and the end of the considered minute.
-
GUV
Gross Upward Activated Volume
Sum of all upward activated reserves. The values published at a given minute are computed taking into account the average of all the activations requested by Elia between the start of the quarter hour and the end of the considered minute.
-
MIP
Marginal Incremental Price
The highest price paid by Elia for upward regulation during the quarter-hour in question.
The values published at a given minute are computed taking into account all the upwards activations requested by Elia between the start of the quarter hour and the end of the considered minute.
-
MDP
Marginal Decremental Price
The highest price paid by Elia for downward regulation during the quarter-hour in question.
The values published at a given minute are computed taking into account all the downwards activations requested by Elia between the start of the quarter hour and the end of the considered minute.
-
IGCC-
International Grid Control Cooperation Downwards
Exports to neighbouring Transmission system operators in case of positive imbalances. The values published at a given minute are computed taking into account all the data between the start of the quarter hour and the end of the considered minute.
-
IGCC+
International Grid Control Cooperation Upwards
Exports to neighbouring Transmission system operators in case of positive imbalances. The values published at a given minute are computed taking into account all the data between the start of the quarter hour and the end of the considered minute.
-
R2-
Secondary Reserve Downards (aFRR)
The values published at a given minute are computed taking into account all the activations requested by Elia between the start of the quarter hour and the end of the considered minute.
-
R2+
Secondary Reserve Upwards (aFRR)
The values published at a given minute are computed taking into account all the activations requested by Elia between the start of the quarter hour and the end of the considered minute.
-
Bids-
Non-contracted regulation reserves activated downwards (non-contracted mFRR)
The values published at a given minute are computed taking into account all the activations requested by Elia between the start of the quarter hour and the end of the considered minute.
-
Bids+
Non-contracted regulation reserves activated upwards (non-contracted mFRR)
The values published at a given minute are computed taking into account all the activations requested by Elia between the start of the quarter hour and the end of the considered minute.
-
R3 Std
Tertiary reserve Standard activated upwards (mFRR)
The values published at a given minute are computed taking into account all the activations requested by Elia between the start of the quarter hour and the end of the considered minute.
-
R3 Flex
Tertiary reserve Flex activated upwards (mFRR)
The values published at a given minute are computed taking into account all the activations requested by Elia between the start of the quarter hour and the end of the considered minute.
-
Inter-TSO Export
Inter-TSO (reserve sharing) reserve Flex activated downwards
The values published at a given minute are computed taking into account all the activations requested by Elia between the start of the quarter hour and the end of the considered minute.
-
Inter-TSO Import
Inter-TSO (reserve sharing) reserve Flex activated upwards
The values published at a given minute are computed taking into account all the activations requested by Elia between the start of the quarter hour and the end of the considered minute.
-
SRStrategic Reserve price or volume when there is a volume >= 0MW of Strategic Reserve activated in the system between the start of the quarter hour and the end of the considered minute.

Disclaimer
If the activated strategic reserve volume is greater than 0 MW, the MIP, IGCC+, R2+, Bids+, R3+, MDP, IGCC-, R2- and Bids- columns of the prices table will not be used to calculate imbalance prices because the strategic reserve is active. The imbalance price will be shown in the column with the SR. To understand how imbalance prices are calculated when the strategic reserve is active, see Article 6.7.2 of the Rules on the Operation of the Strategic Reserve.
