# The 50 largest energy companies in Mexico

Tamtam tracks 66 energy companies headquartered in Mexico. This list ranks the 50 largest by number of employees on LinkedIn, led by PEMEX, Comisión Federal de Electricidad and Xignux. Their median headcount is 590. Half of them were founded in 1979 or later. The most common headquarters are Mexico City (8), Monterrey (4) and San Pedro Garza García (3).

These energy companies in Mexico are primarily large, established firms operating in the oil and gas sector, electricity generation, and related industrial services. Key players include PEMEX, a major contributor to Mexico's oil industry, and Comisión Federal de Electricidad, which generates and distributes electricity. Other significant companies are Xignux, involved in energy and food industries, and Cotemar, specializing in offshore oil services.

The data reveals a concentration of headquarters in major urban centers like Mexico City, Monterrey, and San Pedro Garza García. While many companies have long histories, such as PEMEX (founded 1938) and Comisión Federal de Electricidad (founded 1937), newer entities like CFE Suministrador de Servicios Basicos (founded 2016) also play a role in the evolving energy landscape.

## How this list is built

Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 13, 2026.
