Imbalance Prices 1min
-
QuarterStart and end time of the corresponding quarter hour.
-
MinuteThe 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): no error registered during the calculation and publication run. The published data are likely but have not been validated by an operator
- Data issue: at least one error registered during the calculation and publication run. The published data are uncertain and must be reviewed by an operator
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.
-
SI
System Imbalance
The system imbalance is calculated for each quarter-hour using the difference between the Area Control Error (ACE) and the NRV.
The values published at a given minute are computed taking into account the average of the NRV and ACE between the start of the quarter hour and the end of the considered minute.
-
α
Alpha
Additional incentive applied on top of the regulation costs in cases of major system imbalances. The value of the alpha component is computed taking into account the measured SI of previous quarter hours (published on the 15-minute imbalance price table) and the estimated SI for current quarter hour (published in the current table)
-
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.
-
PriceThe imbalance price calculated for each quarter-hour.
-
SR
Strategic Reserve price 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.
