ABB Opens Its First Zero-Emissions Manufacturing Site in Spain

Global electrification and automation company ABB has officially opened its first zero-emissions manufacturing site in Spain, located in Oiartzun, in the Basque Country. The project represents a concrete example of how industrial facilities can decarbonize operations using existing technologies, rather than relying on future breakthroughs.

The Oiartzun site produces low-voltage electrical protection and control solutions used across energy, transport, and industrial applications. While the products themselves play a role in enabling electrification, the significance of the site lies in how it operates. ABB has redesigned energy supply, building systems, and operational processes to ensure that the facility runs without direct carbon emissions.

Electrification and Renewable Energy at the Core

The zero-emissions status of the Oiartzun plant is achieved through a combination of full electrification and renewable energy sourcing. All thermal processes previously dependent on fossil fuels have been replaced with electric alternatives. This includes heating systems and industrial processes that typically represent a large share of emissions in manufacturing environments.

Electricity for the site is sourced entirely from renewable energy, either generated on-site or supplied through certified green electricity contracts. Rooftop solar photovoltaic panels contribute to local generation, reducing dependence on external supply and improving resilience against grid price volatility. Any remaining electricity demand is covered by renewable energy purchased from the grid.

This approach allows the facility to eliminate Scope 1 emissions, which come from direct fuel combustion, while significantly reducing Scope 2 emissions associated with purchased energy. ABB reports that the site now operates with net-zero emissions from energy use, aligned with its internal decarbonisation targets.

Digital Energy Management and Efficiency Gains

Beyond clean energy sourcing, ABB has deployed its own digital energy management technologies to optimise consumption across the site. Real-time monitoring systems track electricity use at the level of individual production lines and building systems. This enables operators to identify inefficiencies, adjust processes, and avoid unnecessary energy consumption during periods of low activity.

Energy efficiency measures were implemented alongside electrification. These include upgraded insulation, LED lighting, smart ventilation systems, and automated controls that respond to occupancy and production schedules. According to ABB, the combination of efficiency improvements and digital control reduces overall energy demand, lowering both operating costs and pressure on renewable supply.

The Oiartzun facility also uses predictive maintenance tools to ensure that equipment operates at optimal efficiency. By detecting performance issues early, the site avoids energy losses associated with faulty or degraded machinery.

A Model for Industrial Decarbonization

ABB positions the Oiartzun site as a replicable model rather than a one-off flagship project. Importantly, the technologies used are already commercially available and widely deployed in other contexts. This suggests that similar facilities could be decarbonized without excessive disruption or experimental risk.

For energy-intensive industries, the project demonstrates that electrification can be a viable alternative to fossil fuels when paired with renewable energy and smart energy management. While some sectors face technical constraints due to high-temperature process requirements, many light and medium industrial operations could follow a similar pathway.

The project also highlights the importance of addressing emissions at the facility level. While corporate net zero targets often focus on aggregate emissions, site-level transformation provides clearer accountability and faster results.

Alignment With Corporate Climate Targets

ABB has committed to achieving net-zero emissions in its own operations by 2030 and across its value chain by 2050. The Oiartzun site contributes directly to these goals by reducing operational emissions and serving as a reference for other ABB facilities worldwide.

The company operates more than 300 manufacturing and engineering sites globally. Lessons learned in Spain are expected to inform upgrades elsewhere, particularly in regions where renewable electricity is increasingly available and policy frameworks support electrification.

From a governance perspective, the project also reflects growing pressure on multinational manufacturers to demonstrate tangible progress on climate commitments. Investors, customers, and regulators are increasingly scrutinising whether net-zero pledges translate into operational change.

Implications for Policy and Industry

The Oiartzun site offers insights for policymakers seeking to accelerate industrial decarbonisation. Access to renewable electricity, grid capacity, and supportive regulatory frameworks were critical to the project’s feasibility. Stable energy policy and incentives for electrification can significantly lower barriers to similar investments.

For industrial operators, the case underscores the business relevance of decarbonization. Reduced exposure to fossil fuel price fluctuations, improved energy visibility, and alignment with customer sustainability requirements can strengthen long-term competitiveness.

While not all manufacturing sites can immediately achieve zero emissions, ABB’s experience suggests that incremental steps, starting with electrification and efficiency, can deliver meaningful reductions today.
