As system operator of the main electricity supply in Denmark, Energinet.dk must have access to regulating resources with producers and consumers of electricity. This is necessary in order to satisfactorily balance production and consumption in the electricity supply system.
The need of reserves is covered by Energinet.dk by purchasing regulating reserves and ancillary services from consumers and producers in Denmark and our neighbouring countries. The suppliers of regulating reserves and ancillary services are chosen by call for tenders where a special qualification system is used.
