Siemens Energy buys Northern Ireland's Camlin, strengthening grid monitoring and artificial intelligence

Siemens Energy has agreed to acquire Northern Ireland-based Camlin Group, which specialises in monitoring, analytics and digitalisation of grid assets. The German group hopes the acquisition will strengthen its grid digitalisation portfolio at a time when operators around the world are facing ageing infrastructure, long lead times for transformers and growing pressure from the connection of renewable energy sources. The companies did not disclose the value of the transaction. The deal is subject to regulatory approval and is expected to close by the end of 2026.

Camlin is based in Lisburn, Northern Ireland, employs around 650 people and generates annual revenue of more than £90 million. Founded in 2010, the company operates in the energy and rail systems sectors across Europe, North America, Australia and Asia. Once the transaction is completed, it will become part of Siemens Energy's Grid Technologies division, but is set to continue operating independently under its current management.

Camlin's core business is sensor-based transformer monitoring and its Sapient predictive maintenance analytics platform. According to Siemens Energy, it is precisely the combination of hardware, data and artificial intelligence algorithms that it is seeking. The aim is to shift operators from reactive maintenance—repairing equipment after a fault occurs—to maintenance based on the actual condition of equipment.

This is not an entry into software as such—Siemens Energy already operates a digital grid portfolio, and its parent company Siemens is one of the major suppliers of industrial software. Rather, the acquisition expands specific capabilities in sensor-based monitoring and analytics, bringing ready-made technology, data and established customer relationships.

According to Siemens Energy board member Tim Holt, the development and digitalisation of grids are becoming decisive factors for security of supply, economic growth and the energy transition. Camlin CEO Peter Cunningham said the company's operations and management would remain in place after the takeover.

Connection to the transformer shortage

The timing of the acquisition is linked to pressures that Czech operators are also familiar with. Demand for transformers, substations and other grid components is surging due to electrification, more variable power flows and the rapid expansion of renewable energy sources. Lead times for large transformers are estimated by Deutsche Bank to be around six years. Last year, Siemens Energy invested around €220 million to expand production capacity at its transformer factory in Nuremberg, and competitor ABB is similarly increasing production.

But building new hardware takes years, which is increasing the importance of tools that make better use of existing assets. Real-time monitoring and predictive maintenance can extend the life of transformers, detect risks earlier and reduce the number of unplanned outages. According to a Siemens Energy spokesperson quoted by pv magazine, grid constraints are one of the key bottlenecks in the development of renewable energy sources. The company says that strengthening and better managing the grid is therefore directly linked to the ability to connect more wind and solar power plants, which today often face connection queues.

Digitalisation as a growing market segment

The acquisition fits into a broader consolidation in grid technologies, one of the fastest-growing segments of the energy sector. At the end of April, Siemens Energy raised its full-year outlook, driven by strong orders in this division. Advisory firm DC Advisory, which represented the seller, pointed to significant investor interest in companies focused on the resilience, efficiency and security of critical energy infrastructure.

The nature of competition among major suppliers such as Siemens Energy, ABB and GE Vernova is gradually changing. Whereas they once competed primarily in equipment, an increasing share of value is shifting to the data and software layer. According to Siemens Energy, Camlin's value lies not only in its sensors, but especially in its data and analytics platform built on a hardware and service foundation. The platform also promises recurring software revenue, which is more stable for equipment manufacturers than one-off sales.

The acquisition also has a bearing on Europe's competitiveness and self-sufficiency. According to European Commission estimates, nearly €600 billion will need to be invested in grids by 2030, and around 40% of Europe's grid infrastructure is more than 40 years old. The takeover of a Northern Irish company by a German group is also an example of cross-border consolidation in the European grid technology market.
