GE Vernova acquired Prolec to capture transformer manufacturing capacity at a moment when global lead times have stretched to five years, driven by data-centre electrification demand. Prolec added $5bn to GE Vernova's backlog, and the deal gives GE Vernova the Americas' largest transformer manufacturer.Source: Lowdown data-centres

Why is there a transformer shortage for data centres?

Hyperscalers are ordering grid-scale transformers at an unprecedented rate to connect new data-centre campuses. Supply chains take years to scale: transformer factories require specialised steel, copper windings, and experienced engineers. GE Vernova's data-centre electrification orders alone hit $2.4bn in Q1 2026 — more than its full-year 2025 total.Source: Lowdown data-centres

Where are Prolec GE transformers manufactured?

Prolec's primary manufacturing is in Apodaca, Nuevo León, Mexico, with additional facilities in the United States and two factories in India. The Mexican base provides nearshore supply for the US data-centre market.Source: Wikipedia / ProlecGE

Background

Prolec GE (officially ProlecGE) is the largest transformer manufacturer in the Americas, headquartered in Apodaca, Nuevo León, Mexico. Founded in 1969, the company held approximately 14% of the US transformer market as of 2014. Until April 2026 it operated as a joint venture between Mexican industrial conglomerate Grupo Xignux and General Electric, with each holding roughly half the equity.

In April 2026, GE Vernova completed a $5.28 billion acquisition of Xignux's remaining 50% stake, bringing Prolec fully under GE Vernova's ownership. The deal added $5 billion of transformer backlog to GE Vernova's books at a moment when lead times across the global transformer market have stretched to five years — a supply constraint driven directly by hyperscaler data-centre demand. GE Vernova's total backlog reached $163 billion at end-Q1 2026, up $13 billion in 90 days.

Prolec's Mexican manufacturing base and US production facilities give GE Vernova nearshore transformer capacity that is insulated from the transatlantic shipping constraints affecting European suppliers. For hyperscalers racing to connect new data-centre campuses to the grid, Prolec's production throughput is a direct determinant of how quickly new facilities can become operational.

How the World Sees Them

Europe

European transformer manufacturers like Siemens and Hitachi Energy are watching Prolec's integration into GE Vernova closely: GE's combined Americas capacity gives it a structural cost advantage in the US market.

Mexico

The $5.28bn acquisition is one of the largest foreign investments in Mexico's industrial manufacturing sector in recent years, though full GE Vernova ownership removes the Xignux family's Mexican control over a nationally significant manufacturer.

United States

For US grid operators and data-centre developers, Prolec's nearshore Mexican production is a strategic asset: it reduces shipping time versus European suppliers while avoiding the tariff and logistics complexity of Asian manufacturing.
