Energy Minister Labels Galp's Refining Tie-Up With Spain's Moeve 'Complex' as Lisbon Weighs Sovereignty Before a Summer Close
Environment and Energy Minister Maria da Graca Carvalho called Galp's planned downstream merger with Spain's Moeve 'a complex matter' the government is tracking closely, as the oil group targets a signing before August and Lisbon presses for guarantees on the Sines refinery and jobs.
Portugal's government is treating Galp's planned alliance with Spanish energy group Moeve as a delicate balancing act. In an interview on the programme Conversa Capital (a joint Antena 1 and Jornal de Negócios broadcast), the Minister of Environment and Energy, Maria da Graça Carvalho, described the deal as "um assunto complexo" ("a complex matter") that the executive is following "a par e passo" — step by step.
The comments land as Galp, Portugal's largest energy company, pushes to sign a binding agreement with Moeve — the Spanish group formerly known as Cepsa — before August.
What the deal would create
The non-binding framework, announced in January, would combine the two companies' downstream operations on the Iberian Peninsula — the refining and fuel-retail businesses that turn crude into petrol, diesel and jet fuel and sell it at the pump. Under the outline, Galp would hold 50% of a new fuel-retail company and 20% of a separate industrial company covering refining, producing two of the largest operators in the Iberian market.
For Galp, the logic is scale: a bigger combined refining footprint is better placed to absorb the heavy investment needed for the energy transition. The minister pointed to second-generation biofuels, sustainable aviation fuel (SAF) and hydrogen as the technologies that will define the sector's future, all of which demand capital, technology and market incentives that a larger platform can more easily marshal.
Lisbon's red lines
The government's caution is rooted in a single concern: keeping a working refinery on Portuguese soil. Galp operates the refinery at Sines, the country's only remaining facility of its kind after the Matosinhos plant near Porto wound down. Carvalho framed the challenge as reconciling two goals at once — letting the refining business gain the scale it needs to stay competitive, while ensuring that Portugal retains sovereignty over a strategic asset and is not left dependent on facilities across the border.
She stressed the refinery's role as a buffer during energy crises, when secure access to fuels such as aviation kerosene becomes a national-security question rather than a commercial one. The executive is also seeking assurances on the protection of jobs and the continuity of operations as the structure is finalised.
A long-running file
The Galp–Moeve talks have been a fixture of Portugal's energy debate since the start of the year, with former officials and regulators floating remedies — from shareholder agreements to regulatory conditions — to safeguard the national interest. The government has repeatedly said it is "attentive" to the process without holding a veto over a private transaction.
With Galp aiming to close before the summer break, the coming weeks will test whether the company can satisfy Lisbon's demands on supply security and the Sines plant while still delivering the Iberian scale that underpins the rationale for the merger. For now, the minister's verdict is deliberately measured: a complex matter, watched closely, with no signature yet on the table.
