NMX-J-116-ANCE Market
Power Infrastructure
in Mexico.
Mexico's grid is operated by CFE under CENACE coordination with NMX-J-116-ANCE as the primary distribution-transformer specification. ETS manufactures CFE-spec pad-mounted and substation units for nearshoring industrial growth in Monterrey and Mexico City.
Market context
Grid topology, regulation & demand drivers.
Mexico's electricity sector is dominated by the state-owned Comisión Federal de Electricidad (CFE), which operates generation, transmission and distribution under coordination by the National Energy Control Center (CENACE). Voltage levels are 13.8/23/34.5 kV at MV and 115/138/230/400 kV at transmission, with the country's grid divided into nine control areas plus Baja California (interconnected with WECC/CAISO). The dominant distribution-transformer specification is NMX-J-116-ANCE — a Mexican adaptation of ANSI/IEEE C57 — with ANCE certification mandatory for utility procurement and seismic class S2 requirements for the central highlands and Pacific coast fault zones. The 2024 grid reforms strengthened CFE's procurement role and prioritize local-content scoring. Demand is driven by an unprecedented nearshoring boom — automotive (Toyota, BMW, Stellantis, Tesla Gigafactory Mexico in Nuevo León), electronics and aerospace clusters in Monterrey, Guadalajara, Querétaro and Bajío — plus growing data-center buildout in Querétaro and the Riviera Maya tourism corridor. The Sonora Plan adds 1 GW of utility-scale solar with associated step-up transformers. ETS manufactures CFE-spec and NMX-J-116-ANCE certified units via East-Coast (Veracruz, Altamira) and Pacific (Lázaro Cárdenas, Manzanillo) ports from our ISO 9001 manufacturing facility.

Frequently Asked Questions — Mexico
Lead times for projects in Mexico depend on the specification, scope of supply, order volume and prevailing factory load. Distribution transformers (11–33 kV, up to 5 MVA) typically build and test faster than power transformers (33–132 kV, up to 60 MVA), and EHV units above 132 kV require the longest manufacturing and testing windows. Every quoted programme includes witnessed Factory Acceptance Testing at our Jebel Ali high-voltage lab and agreed delivery terms, across the 3 cities we serve in Mexico. Please contact ETS with your technical schedule for a project-specific delivery plan.
