Ancillary services secure the power supply by regulating the frequency, voltage and power load in the network. While large thermal power plants usually provide such services, decentralized generation plants, consumers and storage facilities would also be technically capable of taking over many tasks to ensure system security. The study shows that decentralized facilities in distribution networks have the potential to cover large parts of the stationary reactive power requirements of transmission networks in 2050 if they meet the necessary technical requirements and appropriate coordination processes are established.

In order to promote the further development of system services, dena initiated the Ancillary Services Platform , which serves as a link between market players (network operators, plant operators, manufacturers, etc.), authorities, politicians, and the professional public.
