He later co-founded CN Utility Consulting (now EOCENE), serving as president for 17 years. A pioneer in utility technology, Stephen drove the adoption of LiDAR, UAS, satellites, remote sensing, and AI-driven inventory and work management systems, reshaping how utilities monitor risk, manage vegetation, and protect infrastructure. His work also extends to wildlife habitat monitoring, pollinator protection, and environmental applications.

Stephen helped craft key regulations and standards, including NERC FAC-003 and California's GO 95 Rule 35, and has consulted with utilities across three continents, serving as an expert witness in more than 40 cases.

His contributions have earned broad recognition: a Certificate of Appreciation from the U.S. and Canadian governments for co-leading the 2003 Northeast Blackout UVM investigation (commissioned by FERC); recognition in 2011 by Green Media as one of the eight most influential people in the green industry; and a 2022 UAA Award honoring The UVM Podcast, which he co-hosts with Nick Ferguson, for advancing industry education and innovation.
