About 95% of gas imported by Portugal in 2025 arrived through the Liquefied Natural Gas (LNG) terminal in Sines, according to a report by the Energy Services Regulatory Authority (ERSE). The main countries of origin were Nigeria, with 50% of unloading operations, the United States with 43% and Russia with the remaining 7%. Forty-six LNG carrier unloadings were carried out at the terminal, seven fewer than in 2024, and 7,546 tankers were supplied, 214 more than the previous year.
Portugal intends to end Russian LNG imports by early 2027, under European rules that determine the progressive elimination of gas purchases from Russia. The Spanish company Naturgy is the only one with a long-term contract to import Russian gas through Sines, having received three Russian LNG carriers, the same number as in 2024, with an unloaded energy of 3.3 terawatt-hours (TWh), also unchanged.
The remaining approximately 5% of gas that entered Portugal arrived by pipeline, through the interconnections with the Spanish network in 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. No interruptions were recorded at transmission network exit points for the sixth consecutive year, although Lisboagás did not meet the standard regarding the average number of interruptions.
