IN Brief:
- ABB will invest around $200m in European medium-voltage manufacturing over three years.
- The programme includes a new $100m facility in Dalmine, Italy, and capacity upgrades in five other countries.
- The investment targets switchgear, automation, breakers, relays, GIS, and SF6-free grid equipment for utilities and electrification projects.
ABB is investing around $200m across Europe to expand medium-voltage grid equipment manufacturing, with the programme directed at rising demand from utilities, grid operators, data centres, transport electrification, and industrial decarbonisation.
The investment will be delivered over three years. Around $100m will support a new facility in Dalmine, Italy, while a further $100m will expand and upgrade existing sites in Bulgaria, Finland, Germany, Norway, and Poland. ABB expects the programme to increase selected medium-voltage product capacity by between 50% and 300% and create around 800 jobs.
The product scope includes medium-voltage switchgear, grid automation equipment, gas-insulated switchgear, vacuum interrupters, breakers, relays, and SF6-free technologies. Rather than serving a single end market, the expansion addresses the equipment base needed for distribution networks, industrial power systems, data-centre connections, renewable integration, and high-power charging infrastructure.
Medium-voltage systems are carrying a growing share of Europe’s electrification workload. Transmission investment attracts much of the public attention, but new load and distributed generation have to connect through substations, feeders, switchgear, protection systems, transformers, and increasingly automated distribution assets. The rise of data centres, electrified transport, heat electrification, industrial decarbonisation, commercial solar, and storage is adding demand across that layer of the power system.
Manufacturing capacity has become a delivery constraint as those programmes accelerate. Grid projects can have funding, planning, and network approval in place, yet still face delays when switchgear, transformers, relays, control systems, or specialist components are on long lead times. Expanding production closer to European demand gives utilities and developers another route to more predictable delivery, particularly for product lines that are now under pressure across multiple countries at once.
The Dalmine investment adds new depth in Italy, while the wider upgrades strengthen production across northern, central, and eastern Europe. That spread reflects the regional character of grid investment, where network reinforcement, industrial load growth, and electrification programmes are moving at different speeds but drawing from overlapping equipment supply chains.
SF6-free equipment is a central part of the expansion. Conventional SF6 has been widely used in high- and medium-voltage switchgear because of its insulating and arc-quenching performance, but its environmental profile has driven a sustained transition toward alternative gases, vacuum technologies, and lower-impact designs. Utilities are now moving those alternatives into procurement frameworks and investment programmes rather than limiting them to isolated pilots.
Automation is becoming equally important. Distribution networks are handling more variable generation, more flexible load, and more active voltage and congestion management. That requires equipment capable of protection, monitoring, control, communication, and integration with digital network management systems. Hardware manufacturing and grid digitalisation are therefore becoming harder to separate.
Siemens and Alliander’s flexibility-led DSO model recently showed how forecasting, data, and operational flexibility are becoming central to distribution system operation. ABB’s expansion supports the physical equipment side of the same transition, covering the switchgear, relays, breakers, GIS, and automation platforms needed to make more active network operation dependable.
High-power transport charging is another growing demand source for medium-voltage equipment. ABB E-mobility’s megawatt charging architecture illustrates how charging infrastructure is moving beyond individual units into site-level power systems. Multi-megawatt charging locations require incoming supply, protection coordination, transformers, switchgear, metering, storage integration, thermal management, and controls designed as a coordinated electrical package.
Data centres place similar pressure on the equipment chain. Large campuses can behave like major grid connections, requiring high levels of redundancy, power quality, protection selectivity, and maintainability. As digital infrastructure continues to expand, medium-voltage availability will increasingly influence both network planning and private investment decisions.
ABB’s European investment places manufacturing capacity inside the broader grid resilience equation. More factories will not resolve planning, skills, permitting, or connection queues on their own, but without sufficient switchgear, relays, breakers, automation equipment, and SF6-free grid technology, those programmes cannot move at the required pace. Medium-voltage manufacturing is becoming one of the practical foundations of Europe’s electrification programme.
