GE Vernova Will Pay $9 Billion for the Parts That Hold Up Transformers

GE Vernova agreed on Oct. 28 to buy Trench Group, a Berlin-based maker of high-voltage components, for $9 billion, bringing a supplier of transformer bushings, instrument transformers and coils inside the company. The purchase, announced alongside third-quarter results, is expected to close in late 2027 and be funded about equally with cash and debt. Trench is being sold by the investment firm Triton Partners, and its products will feed GE Vernova's two largest Electrification businesses, Grid Systems Integration and Power Transmission.

The quarter behind the deal was unusually large. GE Vernova booked $29.3 billion in orders, up 96% organically, and closed September with a total backlog of $197 billion, up $20 billion in three months. Its Electrification segment reported $3.86 billion in revenue, a 19.1% segment margin, and $42.2 billion in equipment backlog, 60% higher than a year earlier. Trench runs 11 factories in eight countries with more than 3,000 employees, about $1.4 billion in annual revenue, and roughly $5 billion in combined backlog and framework agreements. GE Vernova puts the global high-voltage equipment market at about $90 billion in 2025, growing to $130 billion by 2030, with North American demand rising faster than the global average.

The components matter more than their cost suggests. Chief Executive Scott Strazik said bushings account for about 5% to 8% of a transformer's bill of materials and that GE Vernova buys most of its bushings from outside suppliers. A study funded by the Energy Department and published in August found that procuring a typical 100-megavolt-ampere power transformer takes two and a half to three years, and that extra-high-voltage units can take five, with bushings, grain-oriented electrical steel, copper conductors and on-load tap changers among the constrained parts.

That constraint sets the sequence of substation work. Grounding grids, duct banks, conduit, cable pulls and control wiring get scheduled around equipment delivery dates rather than the other way around, and an energization date that slides is more often a gear date than a labor date. Trench's plant in Charlotte, North Carolina, its only United States factory, is expected to begin producing bushings rated to 765 kilovolts in late 2027, starting at up to 3,500 units a year with room to reach 10,000.

The hiring consequence runs through substations rather than through factories. Strazik said GE Vernova projects that more than 55,000 United States transmission substations will need to be rebuilt or upgraded to higher voltages over the next decade. Kentucky Power has scheduled construction of a new 765-kilovolt substation to begin in February 2027, with two 765-kilovolt transmission lines to follow later that year, serving TeraWulf's planned one-gigawatt Muskie data campus. That work pays for medium- and high-voltage terminations, cable testing, protective relay wiring and commissioning support, which is a different skill set from distribution and branch-circuit installation.

Vertical integration does not shorten a transformer queue on its own. It moves one bottleneck inside the company that owns the backlog.
