REN Warns Middle East Conflict Will Push Up Portuguese Energy Bills

The president of REN, Portugal's national energy grid operator, has warned that rising fuel prices driven by the Middle East conflict will inevitably reach household and business energy bills. In an interview with Jornal de Negocios, Rodrigo Costa said the impact is already being felt in wholesale markets and will filter through to final consumers.

"Fuel prices are already changing, and those changes always have an impact on the final prices of natural gas and electricity," Costa said. He cautioned that prolonged instability in the region could cause "very serious disruptions to supply chains, with general repercussions across all sectors."

Better Prepared Than 2022, but Not Immune

Costa drew a comparison with the energy crisis triggered by Russia's invasion of Ukraine in 2022, arguing that Portugal's energy system is now more resilient. "The Portuguese energy system is robust insofar as possible and is better prepared than in 2022," he said.

That improved position reflects several years of investment in renewable energy capacity, grid infrastructure, and the diversification of gas supply sources. Portugal's LNG terminal at Sines, one of the most efficient in Europe, has played a key role in reducing dependence on pipeline gas.

However, Costa suggested the terminal's capacity needs to grow. "We have an oceanic LNG terminal that is among the most efficient in Europe, but it is sized to meet the needs of our country," he noted, implying that Portugal should think bigger — both for its own energy security and as a potential gateway for supplying other European markets.

The Broader Energy Picture

The warning comes at a sensitive moment. Global oil and gas markets have been volatile since military operations in the Strait of Hormuz region intensified, with Brent crude prices climbing and European natural gas futures following suit. Portugal, which imports the vast majority of its fossil fuels, is particularly exposed to price swings even as it accelerates its renewable energy transition.

For households, the practical effect may show up in the next round of regulated tariff adjustments. Businesses, particularly in energy-intensive sectors like manufacturing and logistics, face more immediate cost pressures that could feed into broader inflation.

What Residents Should Watch

Energy costs are one of the most tangible ways geopolitical events filter into daily life. For residents in Portugal — including the large expat community that has settled here in part because of a lower cost of living — any sustained increase in electricity and gas prices erodes that advantage.

Costa's message is clear: Portugal is in better shape to absorb shocks than it was four years ago, but it is not insulated from the consequences of a widening conflict in one of the world's most critical energy corridors. The coming weeks will test whether the country's improved infrastructure can keep the worst of the price increases at bay.
