Europe's energy transition depends on more than renewable generation and grid investment. It also depends on the materials that make electrification possible. 

One of those materials is grain-oriented electrical steel (GOES), a critical component in power transformers that enable electricity to move efficiently across transmission and distribution networks. 

In March 2026, the European Commission launched a safeguard investigation into imports of GOES, citing concerns around rising import volumes and the impact on European producers. While the investigation is still underway, it has already sparked discussion across the transformer value chain. 

For manufacturers, suppliers, utilities and grid operators, the announcement raises important questions about supply security, production capacity and the future resilience of Europe's electrical manufacturing sector. 

Why GOES matters 

GOES is a specialised electrical steel designed to minimise energy losses within transformer cores. Its magnetic properties make it essential for the production of power and distribution transformers used throughout energy networks. 

As Europe accelerates investment in grid infrastructure, renewable energy integration, data centres and EV charging networks, demand for transformers continues to grow. 

That demand starts with materials. 

Without reliable access to electrical steel, transformer manufacturers face increased challenges in maintaining production schedules, managing costs and meeting delivery commitments. 

A market already under pressure 

The investigation comes at a time when the transformer industry is experiencing unprecedented demand. 

Utilities across Europe are investing heavily in network expansion and modernisation. Grid operators are working to connect increasing volumes of renewable generation while accommodating growing electricity demand from industry, transport and digital infrastructure. 

At the same time, manufacturers continue to navigate several persistent challenges: 

• Long lead times for critical materials 

• Supply chain volatility 

• Manufacturing capacity constraints 

• Skilled labour shortages 

• Rising customer expectations around performance and sustainability 

For many transformer manufacturers, securing electrical steel remains a strategic priority rather than a routine procurement exercise. 

What is the Commission investigating? 

The European Commission's investigation will assess whether increased imports of GOES are causing serious injury to EU producers. 

Safeguard investigations differ from anti-dumping cases because they focus on the impact of import volumes rather than allegations of unfair pricing. 

If the Commission concludes that safeguard measures are necessary, potential outcomes could include import restrictions or other temporary measures designed to support domestic production. 

The investigation will also consider the interests of downstream industries, including transformer manufacturers that rely on access to electrical steel. 

What could this mean for transformer manufacturers? 

At this stage, no measures have been introduced and the outcome remains uncertain. 

However, the investigation highlights a broader challenge facing the industry: balancing supply security with supply availability. 

European transformer manufacturers are already managing growing order books while working to reduce delivery risk. Any changes affecting material flows could influence: 

Procurement strategies 

Manufacturers may place greater emphasis on supplier diversification, long-term sourcing agreements and strategic inventory planning. 

Capacity planning 

As demand continues to rise, production planning becomes increasingly dependent on confidence in material availability. 

Cost management 

Electrical steel represents a significant input cost for transformer production. Any market changes affecting availability or pricing will be closely monitored throughout the sector. 

Supply chain resilience 

Many organisations are reassessing how they build resilience into their operations, moving beyond cost considerations to focus on security of supply and long-term reliability. 

Why grid operators should be paying attention 

The implications extend beyond manufacturing. 

Transmission system operators (TSOs) and distribution system operators (DSOs) are investing billions in infrastructure to support electrification, renewable integration and energy security. 

Yet many of the challenges facing grid projects originate much earlier in the value chain. 

Transformer availability has become a growing concern across Europe. Long lead times can delay network upgrades, renewable connections and major infrastructure projects. 

The GOES investigation serves as a reminder that grid delivery depends not only on engineering expertise and investment, but also on the availability of critical materials and manufacturing capacity. 

For grid operators, understanding the realities facing suppliers is becoming increasingly important when planning future projects. 

A broader conversation about European competitiveness 

The investigation also raises wider questions about the future of industrial competitiveness in Europe. 

As global demand for electrical infrastructure continues to increase, manufacturers across the value chain are seeking ways to strengthen resilience while remaining competitive internationally. 

For the transformer sector, success will depend on collaboration across the entire ecosystem: 

• Material suppliers 

• Component manufacturers 

• Transformer OEMs 

• Utilities and grid operators 

• Policymakers and regulators 

Each plays a role in ensuring Europe can meet the growing demand for electrical infrastructure. 

Looking ahead 

The outcome of the Commission's investigation remains to be seen. 

What is already clear, however, is that electrical steel has become a strategic material in the transition to a more electrified economy. 

As demand for transformers continues to grow, conversations around supply security, manufacturing capacity and value chain resilience will only become more important. 

For the industry, this is about more than trade policy. 

It is about ensuring the materials, technologies and partnerships are in place to support the next generation of grid infrastructure and keep Europe's electrification ambitions moving forward.
