Elia Open Data

Elia, part of Elia Group, is Belgium's electricity transmission system operator. Elia is responsible for ensuring the secure and efficient flow of electricity from generation facilities to distribution system operators and large industrial users. Open data provided by Elia is essential for understanding and effectively managing the electricity network.

Available Datasets

Currently, the following dataset available is imbalance prices per quarter-hour (Near real-time).

This dataset provides detailed information on the imbalances in the electricity grid. The data includes timestamps, imbalance values in megawatts (MW), and other relevant metrics that help monitor and analyze the stability of the grid. The dataset is updated every 15 minutes with H-1 data. This near real time update allows to reflect the most current status of the network.

Different variables are available with this dataset:

Elia name	Data Hub variable name
Marginal decremental price	MDP
Marginal incremental price	MIP
Imbalanceprice	PNeg & PPos
System imbalance	SI
System imbalance + ACE	NRV

As of 2024-05-22, Elia has migrated the Imbalance Data to a new API. To maintain data continuity for existing customers, the same variables have been retained. However, NRV data is no longer available directly through Elia and is now calculated as imbalance + ace. PNeg and PPos have been combined into a single value, the imbalance price, as both PNeg and PPos were previously populated with the same data from Elia.
