  • The rule on the compatibility of the process in which transportation system operators (hereinafter-TSO) shall coordinate the network users submitted nominations and renominations approval are as follows:The main connection rule is the rule of lesser quantity. 
    • TSO can apply other rules for the alignment of renomination, if any of the TSO network rules provide restrictions.
    • On the border of Lithuania and Latvia, the suggestive TSO is AB „Amber Grid”, and the interconnective TSO is JSC „Conexus Baltic Grid”
    • On the border of Estonia and Latvia, the suggestive TSO is AS „Elering”, and the interconnective TSO is JSC „Conexus Baltic Grid”
    • The interconnection process for nominations begins day D-1 at 15:00 Eastern European time (Eastern Europe summer time);
    • The main interconnection rule is the rule of lesser quantity. TSO can apply other rules for the renomination of interconnection, if any of the TSO network rules provide restrictions.
    • TSO sends to network users confirmed nominations until day D-1 17:00 Eastern European time (Eastern Europe summer time);
    • Renomination cycle starts every hour in course of renomination period;
    • TSO sends to network users confirmed renominations two hours after the start of each renomination cycle.
  • The rules of the allocation of quantities of gas are as follows:
    • TSO provides the assigned amount agreed upon on both sides of the interconnection point;
    • The assigned amount of gas on a single day for a network user is equal to the amount indicated in the nomination, confirmed to the network user by the TSO;
    • The difference between network users approved nominations and measured gas volumes (main difference) is credited to both TSO administrated operational balancing account;
    • In the period, which is decided depending on both TSO’s communicated working schedules, both TSO’s should strive to maintain the operational balancing account balance, as close to zero as possible.
  • Emergency communication procedure for unprecedented events is as follows:
    • TSO provides implementation of communication procedures in place, to facilitate rapid and simultaneous communication in case of an emergency.
  • Informative communication between TSO goes on verbally, followed by a written electronic confirmation, unless it specified otherwise;
    • In the events of an emergency, the affected TSO should at least inform their network users, if it may affect their approved amounts, and provide all the necessary information about:
    • Potential impact on the approved amounts to the network users, who use the interconnection point.
    • The expected and actual emergency event ending.
    • The emergency event affected TSO should at least inform the nearby TSO, about the emergency event occurrence and provide all the necessary information about:
    • Potential impact on the transported gas quantity through the interconnection point and the quality;
    • The expected and actual emergency event ending.
