Five European Union countries are moving forward with a proposal to implement a new tax on energy companies , in direct response to the price increases caused by the conflict in Iran.
The initiative, led by Spain along with Germany, Italy, Austria, and Portugal, seeks to capture some of the sector's extraordinary profits and redistribute them to mitigate the economic impact on consumers and industry. "The conflict in the Middle East has caused a rise in oil prices, which represents a considerable burden for the European economy and for European citizens."
"It is important that this burden be distributed equitably," the ministers stated in the letter, dated April 3 and addressed to Wopke Hoekstra , European Commissioner for Climate, Climate Neutrality and Clean Growth. The proposal comes amid heightened tensions in international energy markets , where oil and gas prices have risen steadily since the start of the Middle East crisis.
This situation is already impacting electricity costs, inflation, and industrial competitiveness in Europe, reopening the debate on mechanisms for state intervention. Within this framework, the International Energy Agency (IEA) warns of an unprecedented energy crisis , marked by combined pressure on oil, gas, and supply systems.
Faith Birol, Executive Director of the IEA, warned: "It is more serious than the crises of 1973, 1979 and 2022 combined , reflecting the magnitude of the challenge facing global energy systems. One of the critical points is the disruption of strategic supply routes , especially in the Middle East."
The risk to hydrocarbon transit through the Strait of Hormuz, key to world trade, adds uncertainty and additional pressure on prices, in a context where supply is already restricted.
The conflict with Iran is shaking up the global energy sector: how is it affecting Europe and Latin America?
The crisis once again highlights Europe's structural vulnerability to imported fossil fuels , especially in those markets where gas continues to be a determining factor in electricity pricing. However, the impact is not uniform across the bloc .
Spain is better positioned thanks to the greater penetration of renewable energies in its electricity mix. Wind and solar power accounted for nearly 60% of generation in March , significantly reducing the impact of gas on pricing.
This partial decoupling from fossil fuels translates into greater relative stability in the face of external shocks. Alongside the push for the European tax, Spain is moving forward with a package of measures aimed at strengthening its energy security , combining short-term responses with structural transformations.
The approved plan mobilizes around €5 billion , focusing on accelerating renewable energy development, strengthening grids, boosting energy storage, and reducing costs for energy-intensive sectors. Key measures include the creation of renewable energy acceleration zones, streamlining administrative processes, and promoting energy storage —all crucial elements for increasing the resilience of the electricity system.
Industry Warning: Investment Risks. However, the proposed new tax is generating concern within the renewable energy sector , particularly in the wind power industry. Industry representatives warn that increasing the tax burden at a critical time could affect investment decisions , just when Europe needs to accelerate the deployment of clean energy capacity to reduce its energy dependence.
The Spanish Wind Energy Association (AEE) points out that the price of electricity in Spain in March is below the price of gas, having become decoupled from international fossil fuel prices.
And it states that the average price on the Spanish electricity market (OMIE) was €41.71/MWh, while the price of gas was €52.62/MWh (MIBGAS). "Had the price of gas influenced electricity pricing as intensely as it has in other countries around us, the price would have exceeded €100/MWh, which it did not."
"Electricity prices in the Iberian spot market are among the lowest in Europe, and have remained low with very limited future growth prospects even in the midst of the crisis caused by the war in Iran," they explain.
They add: "Requesting new potential taxes that impact the electricity sector creates legal uncertainty and scares away investors, precisely at the moment when it is most necessary to invest in technologies such as wind power, as a substitute for imported fossil fuels.
We need more wind power, and we need it faster.
A new, unjustified tax would add further regulatory risk, exacerbating an already complicated situation caused by limited growth in new installations, even with structural roadblocks in some Autonomous Communities. The sector's position is clear: the energy transition requires regulatory stability and significant capital investment , so any signal that introduces uncertainty could slow down strategic projects. In this context, the debate unfolding in the European Union combines economic urgency with a long-term vision. While governments seek mechanisms to contain the immediate impact of the crisis, the sector insists on preserving the necessary conditions to accelerate the energy transition and consolidate a system less vulnerable to external shocks.
