From 2019, Ignitis provides the designated supply function of the liquefied natural gas (LNG) terminal. The company took over this activity after the acquisition of another company within the Lietuvos energija group – LITGAS.

To maintain minimum activity of the LNG terminal infrastructure, it requires a certain quantity of natural gas (the necessary quantity), which must be supplied through the LNG terminal filling, degassing and reloading the repositories and supplying to the Lithuanian natural gas system or international LNG market.

The Government of the Republic of Lithuania has confirmed that the minimum annual quantity of natural gas for gasification, required to maintain stable gasification process of the LNG terminal for the first 5 years, starting from the 1 January 2015, shall be 325 – 502,902 million m3 of natural gas per year at 0°C temperature of interest and pressure of 1,01325 bar.

'The law on the LNG terminal of the Republic of Lithuania' and the 'Description of the Natural Gas Supply Diversification Procedure' stipulate that the necessary quantity shall be supplied by the designated supplier  (designated for 10 years by the Ministry of Energy through an open tender), concluding the contract with the LNG supplier.

The designated supplier sells the necessary quantity of LNG in the competitive market and is reimbursed only the expenses exclusively incurred by the designated supplier due to peculiarities of their activities and not by other natural gas suppliers.
