Balancesnettet

Balancesnettet is a term used in Denmark to refer to the national electricity balancing system. It is managed by Energinet, the Danish Transmission System Operator. The primary function of balancesnettet is to ensure that the supply of electricity in the grid at any given moment exactly matches the demand. This is crucial for maintaining the stability and reliability of the power system.

Energinet achieves this by continuously monitoring electricity consumption and production across Denmark. When imbalances occur, meaning a mismatch between supply and demand, Energinet intervenes. This intervention involves activating or deactivating power reserves, which are essentially flexible generation units or demand response resources that can be quickly adjusted. The goal is to restore the balance as rapidly as possible to prevent disruptions.

The operation of balancesnettet is complex and involves various market mechanisms. Electricity producers and consumers participate in the balancing market, offering their flexibility to Energinet. Prices in this market fluctuate based on the real-time needs for balancing. Efficient management of balancesnettet is essential for integrating renewable energy sources, such as wind and solar power, which are inherently variable in their output. By ensuring grid stability, balancesnettet facilitates the transition to a greener energy system.
