Elia shares the European ambition to establish an integrated electricity market and encourage different market players to provide system services.

Elia and other TSOs adopt transparent and non-discriminatory processes to calculate and allocate available cross-border transmission capacities. The Transfer of Energy (ToE) framework serves to help grid users enhance the value of the flexibility in their electricity offtake.

System services

System services allow Elia to operate the grid securely. Elia procures these services via contracts with specific providers and divides the services into five separate categories:

  • Outage Planning Agents provide information on the availability of production units
  • Scheduling Agents provide information on production schedules and flexibility available for congestion management
  • Balancing Service Providers offer flexibility for balancing as first, secondary or tertiary control
  • Voltage Service Providers respond to voltage changes automatically or at the request of Elia
  • Restoration Service Providers keep production units available to restore the system in case of a blackout.
