According to a Sidenor press release, the Spanish steel company is implementing an investment plan to decarbonize its Basauri plant under the PERTE de Descarbonización Industrial 2024 program. The initiative focuses on two interconnected areas: electrifying key steelmaking processes and digitalizing energy management. The company views these steps as vital tools for reducing greenhouse gas emissions, improving energy efficiency, and strengthening its competitive edge in the energy-intensive production segment.
What the Decarbonization Plan at the Basauri Site Entails
The first project involves replacing natural gas-fired steam boilers with electric-powered mechanical vacuum pumps. This equipment will be utilized during the steel degassing process in the finishing section of the melt shop. As a result, Sidenor plans to completely eliminate gas consumption for boiler operations during this stage of the technological cycle.
Electricity for the new pumps will be sourced from renewables, avoiding an increase in indirect emissions following process electrification. The company estimates this shift will yield annual savings of approximately 35,000 MWh of natural gas. Additionally, an emission reduction of over 6,000 tons of CO2 equivalent per year is expected, while emissions linked to the VD and VOD lines should reach near-zero levels.
The second focus area is the digitalization of energy consumption. Sidenor is deploying an online monitoring system for electricity and gas across various production units, featuring new meters and AI-based predictive models. This enables real-time tracking of deviations, more precise load management, and the identification of additional energy-saving opportunities.
Data from the company indicates that the digital control loop will save over 3,600 MWh of gas and about 3,200 MWh of electricity annually. The projected additional emission reduction is roughly 1,000 tons of CO2 equivalent per year. Both projects are supported under Spain's state program with EU funding via NextGenerationEU.
Impact on the Steel Market and Solutions from winox.ua
For the European metallurgy sector, such investments are indicative of a broader shift where decarbonization moves from regulatory compliance to direct economic expediency. Reducing gas consumption, managing electricity use, and applying digital analytics help manufacturers lower production costs and increase resilience to energy price volatility. This is why such projects are becoming a factor in the long-term competitiveness of European plants.
For consumers of metal products, this translates to gradually tightening requirements regarding the origin, quality, and carbon profile of the metal. Against this backdrop, winox.ua, as a supplier of stainless steel, non-ferrous metals, and rolled steel products, focuses on partnering with manufacturers that meet modern standards of quality and technological modernization. This approach ensures industrial sector clients receive certified products for manufacturing, construction, and metalworking.
The trend toward energy efficiency also shapes procurement policies, with businesses increasingly evaluating not only price but also supply chain stability. In these conditions, winox.ua offers reliable supplies of rolled metal and expert material selection for specific industrial tasks. This is particularly vital for companies undergoing their own modernization and seeking to lower operational costs without compromising on quality.
Why Sidenor's Experience Matters for the Entire Industry
The new modernization phase at Basauri demonstrates that decarbonization in the steel industry is no longer limited to massive investments in generation or total smelting technology shifts. Significant impacts can be achieved through targeted solutions at specific energy-intensive stages when combined with high-quality digital analytics. For many enterprises, this model may prove to be the most realistic path toward low-carbon manufacturing.
It is worth noting that by the end of 2025, Spanish steel mills are projected to have increased production by 0.7% year-on-year to 11.95 million tons. This highlights that energy efficiency and ecological modernization are essential not only for emission reduction but also for maintaining output growth within a stricter regulatory and competitive market. Sidenor’s experience serves as a benchmark for other manufacturers seeking a balance between investment, ecology, and productivity.
