About Us


To ensure our clients are successful by consistently delivering safe, practical engineering solutions that work.


ZinaVolt is a minority-owned engineering company headquartered in Corpus Christi, TX. We specialize in executing turn-key projects in the power, automation, instrumentation and controls field. We manage and execute projects from the conceptual design phase to the commissioning and energization phases. Our projects include designs for electric utilities, industrial and water/wastewater clients with voltage levels that range from 24Vdc up to 345kV.

Meet our founder

ZinaVolt Founder Dr. Aniemi Umana is the founder and president of ZinaVolt and is a registered professional engineering in the state of Texas. Dr. Umana attended Oklahoma State University where he obtained his bachelor’s degree in electrical engineering. He obtained his master’s and doctoral degrees from Kansas State University and the Georgia Institute of Technology (Georgia Tech) respectively, both in electrical engineering with emphasis in power systems protection.

Dr. Umana’s has over 15 year of experience in the electrical power industry providing various engineering solutions to industrial, commercial and utility clients. His experience includes the design of protections schemes, programming of digital relays and implementation of automatic (auto) transfer schemes. He is considered a subject matter expert in short circuit analysis, coordination studies, arc-flash studies and has developed engineering applications for quick fault current computations, motor cable sizing, arc-flash calculations, equipment cable selections and voltage drop calculations.

Some of Dr. Umana’s publications in the renewable energy field include:
