About 95% of the gas that entered Portugal in 2025 arrived through the Sines terminal, according to a report by the Energy Services Regulatory Authority (ERSE). This Liquefied Natural Gas (LNG) terminal was responsible for the overwhelming majority of the country's gas imports during the past year.
In total, 46 unloadings of methane ships were carried out at the Sines terminal in 2025, seven fewer than in 2024. However, the number of tankers supplied increased to 7,546, 214 more than the previous year.
The main countries of origin of the imported gas were Nigeria, United States and Russia. Nigeria represented 50% of the unloading operations, consolidating itself as the main supplier. In 2025, three Russian ships unloaded gas at the Sines terminal.
