Elia publishes cumulative volumes and prices per product of the activated balancing energy per minute

Cumulative activated volumes and prices per minute

This page of cumulative activated volumes and prices describes the balancing energy activated to maintain a balance in Elia’s control area, as well as the strategic reserve activated to ensure adequacy in the Elia control area.

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

At the specified time, the most recent available data are collected and displayed as quickly as technically possible. The cumulative activated volume values published differ from those of the Current System Imbalance, as the latter are instantaneous values.

All published values are non-validated values and can therefore only be used for information purposes.

Legend

Quarter

Start 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.
SR

Strategic 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.

Imbalance prices (1 minute)

Elia publishes an imbalance price calculated based on cumulative activated volumes per minute.
