Balancing Service Provider (BSP) Model and Independent Aggregator

The Nordic Imbalance Settlement model is undergoing changes with the introduction of a new role called the Balancing Service Provider (BSP), responsible for providing balancing energy or capacity to the Transmission System Operator (TSO). This transition involves splitting the current responsibilities of the Balance Responsible Parties (BRPs) into two roles: BRP for imbalances and BSP for balancing energy and capacity, where Independent Aggregator will be participating.

The introduction of the Independent Aggregator in the Nordic Imbalance Settlement model aims to improve the efficiency, competition, and reliability of the electricity market while enabling the integration of renewable energy sources and ensuring grid stability.
