Balance

On the electricity grid, balance refers to the continuous equilibrium between electricity generation and consumption. This balance is essential for a stable and reliable grid. If generation and consumption are not aligned, deviations in frequency and voltage occur, which can lead to wear or damage to installations.

The role of balance in resolving congestion

Electricity generation and consumption are largely planned in advance, based on forecasts. Because reality always deviates, these plans sometimes need adjustment. With every adjustment, maintaining system balance is crucial.

This plays a key role in resolving congestion. For example, if less electricity is transported to a congested area, a surplus arises elsewhere. Without countermeasures, this would lead to imbalance.

Grid congestion, redispatch and balance

Through GOPACS, congestion is resolved intraday via redispatch, without disturbing the national balance. This is done through two simultaneous, opposite actions:

1. Within the congested area
   • less generation or more consumption
2. Outside the congested area
   • more generation or less consumption

This combination reduces the load on the local grid while maintaining the overall balance between supply and demand.
