Approximately 95% of the gas that entered Portugal in 2025 arrived through the Liquefied Natural Gas (LNG) terminal in Sines, according to a report by the Energy Services Regulatory Authority (ERSE). Nigeria was the main country of origin, accounting for 50% of the unloading operations, followed by the United States with 43% and Russia with 7%. Forty-six LNG carrier unloadings were carried out at the terminal, seven fewer than in 2024, and 7,546 tankers were supplied.
Sines received three LNG carriers from Russia, the same number as in 2024, with Russian-origin energy unloaded remaining unchanged at 3.3 terawatt-hours. Portugal intends to end Russian LNG imports by early 2027, under European rules for the gradual elimination of Russian gas purchases. As explained by the Minister of Environment and Energy, Maria da Graça Carvalho, there is a single company with a long-term contract to import Russian gas through Sines: the Spanish company Naturgy.
The remaining approximately 5% of gas that entered Portugal arrived by pipeline, through the interconnections with the Spanish network at Campo Maior and Valença do Minho.
The ERSE report also concludes that in 2025 there was an overall improvement in the performance of gas transmission and distribution networks, with a reduction in the number and duration of supply interruptions. Approximately 0.7% of customer installations were affected by interruptions, corresponding to 10,861 out of a total of 1,567,872 customers connected to the network. In the transmission network, there were no interruptions at exit points for the sixth consecutive year. All distribution network operators met the standard regarding the average duration of interruptions, with the exception of Lisboagás.
