Connection of consumers and gas system operators

This section is for Customers wishing to connect their systems to the transmission system and transport or consume natural gas (this section does not contain information for biogas producers, all relevant information related to the connection of biogas production facilities, biomethane inlet connections from gas carriers is available in the section For biomethane producers).

Connection of new natural gas systems to the existing transmission system is a service provided by the Lithuanian gas transmission system operator Amber Grid (hereinafter - TSO) to the Customer, i.e. the owner of the new gas system (gas consumer or gas system operator), whose gas system is being connected to the TSO system for the first time. TheCustomer shall also be deemed to be an existing consumer who wishes to increase its gas consumption (i.e. increase the capacity of the transmission system) to the extent that the existing capacity of the transmission system is no longer sufficient.

The connection service is provided on the basis of the concluded connection service contract. The TSO advises on all issues related to the connection of facilities to the transmission system:

The main documents governing the procedure for connection to the transmission system are as follows:

The TSO to whose operated transmission system the Customer’s system is connected (except for biogas production facilities, biomethane inlet connections) shall bear the economically reasonable costs of the system development and the connection of the Customer’s system, and the Customer shall bear the costs above the economically reasonable costs of connection. The calculation of the economically justified costs and the costs in excess thereof shall be carried out by the TSO in accordance with the Methodology for setting the fees and rates approved by the National Energy Regulatory Council.

In case the Customer’s future (up to 15 years) obligations to pay for the minimum transmission system capacity and transportable gas volumes have already been foreseen at the time of the issuance of the preliminary conditions for connection, the TSO shall be entitled to request the Customer to provide additional means of security for the fulfilment of its obligations.

Below is provided the basic information that is useful to know when preparing to connect natural gas production facilities to the gas transmission system. Click on the plus sign for more detailed information relevant to that step.
