Nigeria sent half the LNG that landed at Sines last year
Portugal's energy regulator counted 46 tanker unloadings at the Sines LNG terminal in 2025, the entry point for 95% of the country's gas. The United States accounted for 43% of cargoes and Russia for 7%.
Portugal has an energy bottleneck and it sits in Sines. Around 95% of the gas that entered the country in 2025 arrived through the liquefied natural gas terminal there, according to the annual report from the energy regulator ERSE. The other 5% came by pipeline, over the Spanish interconnections at Campo Maior and Valença do Minho.
The terminal closed the year on 46 tanker unloadings, seven fewer than in 2024, and filled 7,546 road tankers, 214 more than the year before.
Where the gas comes from
Nigeria accounted for half of all unloading operations. The United States took 43% and Russia the remaining 7%.
That 7% is three ships — the same number as in 2024 — and the Russian-origin energy landed did not move either, holding at 3.3 terawatt-hours. Portugal intends to end Russian LNG imports by the start of 2027, under the EU rules phasing out gas purchases from Russia. As environment and energy minister Maria da Graça Carvalho explained back in February, only one company holds a long-term contract to bring Russian gas in through Sines: the Spanish utility Naturgy.
The network held up
The least-reported section of the report is the one that matters if you have a meter at home. ERSE found an overall improvement in the transmission and distribution networks, with fewer interruptions and shorter ones.
Supply interruptions touched 0.7% of customer installations — 10,861 out of 1,567,872 connected customers. On the transmission network there was not a single interruption at exit points, for the sixth consecutive year.
Every distribution operator met the standard for average interruption duration. The exception was Lisboagás, which missed the standard for the average number of interruptions, blamed on planned works, leak surveys and network conversion.
Electricity, meanwhile, went in a rather different direction this year: in July solar became Portugal’s largest single source of electricity. The report and the regulator’s other publications are on the ERSE website.
