Capacity products

GTG markets fixed and interruptible capacities:

  • Freely allocable entry and exit capacity (FZK)
  • Conditionally firm, freely allocable entry capacity (bFZK)
  • Firm, dynamically allocable entry capacity (DZK)
  • Interruptible capacity (UK)

The capacity types (especially the supplementary terms and conditions for bFZK,DZK and reverse flow capacity) are described in detail in STC-EE.

Capacity measurement

GTG has measured the technically available capacities in stationary load flow simulations. Interruptible capacity can generally be booked independently of bookings for firm capacity and the maximum technical system capacity.
