Energy Costs Push Spanish Industry to Breaking Point as Steelmakers Halt Production and Manufacturers Face 7.4 Billion Euro Bill

Spain's energy-intensive industries are being pushed to the brink in 2026 as electricity and gas prices surge, forcing steelmakers to halt production during peak hours and threatening factory shutdowns across the manufacturing sector. The Spanish steel industry alone faces a 658 million euro energy overcost between March and December 2026, according to UNESID, the country's steel association. The broader industrial base could absorb a 7.4 billion euro hit by year-end, with gas prices exceeding 80 euros/MWh and electricity projected to reach 143 euros/MWh in the fourth quarter.

This energy shock is not an isolated event. It reflects a convergence of geopolitical tensions, including the Ormuz crisis, with structural weaknesses in Spain's industrial energy framework. The consequences for production, investment, employment, and European competitiveness are becoming increasingly severe as manufacturers warn of production halts and demand urgent government intervention.

Key Takeaways

• The Spanish steel industry faces a 658 million euro energy overcost between March and December 2026, with 452 million euro concentrated in the final four months (UNESID).
• The broader Spanish industrial sector could absorb a 7.4 billion euro energy bill increase by year-end, split between 4.22 billion euro for gas and 3.175 billion euro for electricity (Alianza para la Competitividad de la Industria Espanola).
• Electricity prices are projected to reach 143 euros/MWh in Q4 2026, while natural gas is forecast at 76 euros/MWh.
• Steelmakers are already halting production during peak-price hours, a practice that could intensify if current price levels persist.
• Adjustment services add approximately 20 euros/MWh to the electricity bill for Spanish steel companies, creating a competitive disadvantage versus other European frameworks.
• The industrial alliance is calling for an emergency plan, including increasing 2026 CO2 compensation to at least 1 billion euro.

The Scale of the Energy Shock

The numbers illustrate the magnitude of the crisis. Between March and August 2026, the combined overcost for gas and electricity across Spanish industry reached approximately 2.337 billion euro. For the September-December period, the alliance estimates more than 5 billion euro in additional costs, representing nearly 70% of the total projected impact for the year.

In the steel sector specifically, UNESID calculates that the overcost will reach 658 million euro by December, with 452 million euro falling in the last four months of the year alone, more than double the impact recorded in the first eight months. By energy vector, the overcost breaks down into 403 million euro for electricity and 255 million euro for gas.

Steel Industry Energy Cost Breakdown 2026

The table below summarises the projected energy overcost for the Spanish steel industry and the broader industrial sector.

Why Are Energy Prices Surging in Spain?

The surge in energy prices is driven by a combination of geopolitical and structural factors. The Ormuz crisis has disrupted global energy markets, pushing gas and electricity prices sharply higher. In July 2026, the average electricity market price reached 104.75 euros/MWh, a 50.5% increase from June. Gas prices on the MIBGAS platform averaged approximately 55.5 euros/MWh, up 23.5% over the same period.

But geopolitical tensions alone do not explain the full picture. Spain's industrial electricity costs are structurally higher than those of many European peers due to the design of adjustment services, which add approximately 20 euros/MWh to the bill for steel companies. This creates a competitive disadvantage that compounds the impact of rising wholesale prices.

UNESID has identified adjustment services as a core problem. These costs, which cover system balancing and ancillary services, are particularly burdensome for electro-intensive industries that consume large volumes of electricity continuously.

How Does This Affect Steelmakers and Manufacturers?

The impact on steelmakers is already visible. Companies are halting production during hours when electricity tariffs are highest, a strategy that reduces output and disrupts supply chains. While the sector has historically scheduled operations during off-peak hours to manage costs, this measure is no longer sufficient in the current environment.

Carola Hermoso, Director General of UNESID, has warned that the steel industry cannot indefinitely absorb energy costs that deteriorate its capacity to produce, invest and compete. The association is calling for immediate measures, but also structural decisions that allow companies to count on stable, predictable and competitive energy.

The broader manufacturing sector faces similar pressures. The Alianza para la Competitividad de la Industria Espanola, which represents major industrial players including Alcoa, Ence, Megasa, Celsa, and others, has warned of the risk of factory shutdowns. The alliance estimates that gas alone will add approximately 4.22 billion euro to manufacturing costs, while electricity will contribute another 3.175 billion euro.

What Is the Spanish Government Being Asked to Do?

Industry associations are demanding urgent government action. UNESID is calling for an emergency plan that provides certainty on energy conditions for 2026 and 2027. Among its priorities is increasing the 2026 allocation for indirect CO2 cost compensation to at least 1 billion euro, the maximum permitted under European regulations.

The Alianza para la Competitividad de la Industria Espanola is urging the government to maintain existing support measures and reinforce them with broader actions. The alliance warns that the concentration of cost increases in the final four months of 2026 coincides with the expiration of support measures and higher energy needs linked to production activity.

Carlos Reinoso, spokesperson for the alliance, stated that the Ormuz crisis did not originate the competitiveness problems of Spanish industry, but it has intensified difficulties the sector was already facing. This framing is important: the energy shock is exacerbating pre-existing structural challenges rather than creating entirely new ones.

What Does This Mean for European Industrial Competitiveness?

Spain's energy crisis is part of a broader European challenge. An alliance of 13 major industrial players has stressed that electricity costs in the EU remain significantly above levels that would enable companies to invest confidently in electrified production processes. The group supports a reference price of 50 euros/MWh as the maximum total electricity cost for industry, aligned with the State aid framework supporting the Clean Industrial Deal.

If Spanish industry faces electricity costs of 143 euros/MWh in Q4 2026, the gap with this reference price is stark. This differential has profound implications for investment decisions, as energy-intensive companies evaluate where to locate production and how to structure their operations.

The risk is not only economic but also strategic. If Spanish and European manufacturers cannot compete on energy costs, production may shift to regions with cheaper energy, undermining the EU industrial base and its ambitions for a clean industrial transition.
