Dispatching (of electric energy)

The direct issuance of instructions for the coordinated operation of production plants, of the National Transmission Network, of the networks connected to it and of the electric system's ancillary services.

• frequency regulation
• voltage regulation
• back-up services, i.e. all secondary and tertiary regulation services
