Congestion Risk Indicator (CRI) per electrical zone of the Belgian grid - data as of 22/05/2024
This dataset provides the Congestion Risk Indicator (CRI) for each electrical zone of the Belgian transmission grid, published by Elia, the Belgian transmission system operator. The CRI reflects the level of risk of congestion in a given electrical zone associated with an increase or decrease in active power net injection within that zone. Data is recorded from 22 May 2024 onward, corresponding to the local go-live of the ICAROS system. The indicator supports monitoring of grid congestion risk at a zonal level, offering insight into how changes in power injection could affect the stability and capacity of the electrical network in Belgium.The Congestion Risk Indicator (CRI) represents the status of an Electrical Zone regarding the risk of Congestion associated to the increase or decrease of the active power net injectionin the Electrical Zone This dataset contains data from 22/05/2024 (ICAROS local go-live) on.

| Fill | Field | Type | Description |
|---|---|---|---|
| 100% | datetime | datetime | Time at which the interval starts. |
| 100% | resolutioncode | text | Resolution refers to the duration or length/duration of a Market Time Unit (MTU) used for organizing market activities.It determines with what granularity time is divided within capacity calculation, capacity allocation & cross-border scheduling. |
| 100% | zonename | text | The name of the zone. |
| 100% | cri_level_upCRI level in upward direction | text | A CRI in the upward direction indicates a congestion risk if the net injection in the electrical zone would increase. The increase of net injection in the electrical zone is limited depending on the risk severity. |
| 0.9% | cap_upCap in upward direction | double | Maximum increase of active power net injection allowed in an Electrical Zone with a medium CRI level in upward direction without creating a Congestion |
| 100% | cri_level_downCRI level in downward direction | text | A CRI in the downward direction indicates a congestion risk if the net injection in the electrical zone would decrease. The decrease of net injection in the electrical zone is limited depending on the risk severity. |
| 0.6% | cap_downCap in downward direction | double | Maximum decrease of active power net injection allowed in an Electrical Zone with a medium CRI level in downward direction without creating a Congestion |
