We are primarily tasked with providing power transmission services, system services and facilitating the energy market. Our core tasks follow from our appointment as grid operator under the Dutch 'Elektriciteitswet' (E-wet) and the German 'Energiewirtschaftsgesetz' (EnWG).
TenneT continuously monitors and maintains the balance between the electricity supply and demand on the Dutch and large parts of the German grid.
Supply and demand
TenneT continuously monitors and maintains the balance between the electricity supply and demand on the Dutch and a large part of the German grid. If this balance is disrupted it may result in a power outage or even a black-out, depending on the length and severity of the imbalance.
Whether the balance can be achieved, maintained and restored depends on three factors:
- All connected parties take the required Balance Responsibility and specify how much they expect to feed into and take out of the grid each day;
- TenneT calculates and deploys the reserve and emergency power that connected parties supply;
- TenneT and the programme responsible parties offset imbalances according to the imbalance pricing system.
When there are not enough resources available to restore the balance, we can take additional measures – we have a mandate to prevent or limit potential damage to the power supply.
