Sempra Energy named Carlos Ruiz as chairman and CEO of the company’s Mexican operating subsidiary, Sempra Mexico, the company said June 21.

Ruiz served on Sempra’s corporate board of directors from 2007 to his latest appointment. In the newly created position, Ruiz is responsible for managing all of Sempra’s Mexican operations.

The Mexican unit that is part of Sempra International has nearly 400 employees and $2 billion in assets, including natural gas pipelines and distribution utilities, a liquefied natural gas receipt terminal, and a natural gas-fired power plant.

It is also developing a major wind energy project in northern Baja California.

Ruiz is a partner in an investment banking and infrastructure project firm, Proyectos Estrategicos Integrales SC. Before that, he served as Mexico’s secretary of communications and transportation.

Ruiz also serves on the boards of Southern Copper Corp. and OHL Concesoines Mexico, neither of which have business relationships with Sempra, the company said.

He holds a bachelor’s degree from Anahuac University in Mexico City, and a master’s degree in business administration from Northwestern University in Chicago.
