We provide engineering, consulting, & research services to the electric power industry worldwide.

EnerNex, a CESI company, believes that amid a complex and dynamically shifting energy landscape, depth of expertise and breadth of knowledge are both crucial components for ensuring success and few firms can provide this combined value.

We believe our capability to span energy topics from strategic guidance to detailed engineering analyses, provides maximum flexibility and insight to our clients.

In June of 2016, Erich Gunther, our co-founder, chairman and chief technology officer, passed away unexpectedly at the age of 57.

CESI acquired EnerNex in June 2018, expanding the companies’ global reach, synergizing North American and global competencies in support of the world’s electricity sector.
