Daniel Zaragoza is a retired utility executive with over 40 years of extensive electric operations experience, specializing in electric transmission and distribution operations, emergency management and fire risk mitigation.

Prior to retiring in early 2017, Zaragoza was Director of Emergency Management for San Diego Gas & Electric, one of Sempra Energy’s regulated California utilities serving 3.6 million customers in San Diego and Southern Orange Counties. In this role, Zaragoza was responsible for managing and executing the utility’s response to major emergencies that had the potential to cause severe customer and infrastructure impacts to the gas and electric system in San Diego – the second largest city in the state of California.

Zaragoza managed both the Fire Coordination and Meteorological teams to ensure operational decisions were made using data and expertise from weather and fire mitigation experts. As part of the company’s commitment to keeping the communities it serves safe, Zaragoza was instrumental in developing one of the most comprehensive and robust fire risk mitigation programs in the industry designed to improve grid resiliency.
