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 supplies 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 prioritise 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-centre 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 supplies CFE-spec and NMX-J-116-ANCE certified units via East-Coast (Veracruz, Altamira) and Pacific (Lázaro Cárdenas, Manzanillo) ports in 22–28 days from Jebel Ali.
