Capacity booking and allocation

The TSO offers a long-term capacity from 1-year inclusive, and short-term capacity of up to 1-year, firm and interruptible capacity.

The TSO offers the following standard capacity products at all entry and exit points:

  • Yearly
  • Quarterly
  • Monthly
  • Daily
  • Within-day

If during the allocation of the certain term firm capacity, the demand for capacity exceeds the supply (the demand for capacity is greater than available technical capacity), the TSO shall propose to the System Users interruptible capacity of this term.

Capacity can be booked and confirmed via electronic transmission service booking and administration system (ETSS) or, if ETTS disorders, in writing.

Capacity in Santaka is allocated on the Capacity Booking Platform (GSA Platform) here.

The capacity of Kiemėnai point is distributed using the Common Zone Platform, which is jointly managed by the Latvian and Estonian transmission system operators, here.

 

Long term capacity booking
  • Long-term bookings shall be accepted via ETSS no later than 21 calendar days before the commencement of use of capacity, and no earlier than 6 months before the commencement of the period of use of capacity.

Therefore, the quantity of capacity allocated to the System User shall be equal to the ratio between the quantity of capacity booked at that point by that System User and the total quantity of capacity booked at that point by all System Users, multiplied by the quantity of capacity available with the TSO.

Short-term capacity is allocated on a „first-come, first-served“ basis. The "first come, first served" principle applies only when there is no contractual congestion in the system. In case of contractual congestion in the system or a situation where more than one order is received at the same time, the TSO cannot satisfy the requests of the system users, the remaining capacity after the application of the "first-come, first-served" procedure is allocated to the system users in proportion to the requested capacity amounts.System users willing to use gas transmission capacities are required to have procured sufficient natural gas volumes.
