Transmission System Operators (TSOs) like Elia and TenneT have the responsibility to balance supply and demand. Energy is exchanged between grids in order to have a stable electricity grid, operating at a frequency of 50 Hertz. Connected parties share the responsibility for balancing and have to inform grid operators about their planned injections, offtakes and transports. A connected party is therefore called a Balance Responsible Party (BRP) or Access Responsible Party (ARP) in Belgium.

The challenge of BRPs? The dynamics of the power market require constant attention for balancing offtake and injection. Prices can be heavily influenced because of emergencies disturbing this balance. Therefore forecasting and intra-day follow up are a necessity when operating in the power market.
