    • The Canadian Chair of the IEC Technical Committee 57, which is responsible for preparing international standards for power systems control equipment and systems including substation and distribution automation EMS, DMS, tele-protection, and associated information exchange for real-time and non-real-time information, used in the planning, operation and maintenance of power utility systems.
    • Canadian Chair of the IEC Smart Energy Systems Committee responsible for harmonizing the IEC standards that compose the global Smart Grid Roadmap.
    • Founder of the IEC 61850 University.com, which is an on-line platform used to offer 61850 training, testing and consulting services.
    • Founder of IEC 61850 Process Bus User Task Force, which is composed of over 30 members from 19 utilities across 7 countries.
    • Technical expert within the IEC 61850 Working Group, which is responsible for developing standards for the power utility automation domain.
    • Task Force Leader for the IEC 61850 HMI Task Force and recipient of the Canadian Innovative Initiative Pilot Project
    • Technical expert within Technical Committee 38, Working Group 37, which is responsible for developing standards for NCITs and stand-alone merging units.
    • A member of the UCA International IEC 61850 Testing Committee.
    • This participation has led Dustin to being awarded the 2015 Canadian IEC Young Professional of the Year.

  • Braden OlsonPrincipal Protection & Automation Engineer

    Braden Olson is a Principal Protection and Automation engineer who has more than 15 years of hands-on electric utility experience. Before joining Tesco, he worked as a Senior Engineering consultant for GE, providing protection and automation consulting engineering services for transmission, distribution and generation customers. He acted as lead consultant and key account manager for major utility customers in the Western United States and specialized in digital substation projects.

    Before becoming a consultant, Braden worked at two different utilities. He worked for almost 7 years at Southern California Edison (SCE), in Advanced Technology, where he was responsible for research and development of new substation protection and automation technology. This included developing, piloting and standardizing SCE’s next generation substation automation system based around IEC 61850. He also has extensive experience and knowledge about SCE’s protection and automation standards and design. Before SCE, Braden worked at Salt River Project (SRP) for almost 7 years, in the system protection and control engineering areas. At SRP, Braden worked on several major projects, including designing and commissioning one of the largest Remedial Action Schemes (RAS) in the western United States. Braden has extensive utility experience related to system protection, substation automation, IEC 61850, substation design and commissioning.

    Braden received his Bachelors of Science in Electrical Engineering degree from Montana State University. He is a Professional Engineer in the state of California.

  • Darren De RondePrincipal Protection & Automation Engineer

    Darren De Ronde, P.E. is a Principal Protection Engineer who has more than 20 years of hands-on electric utility experience bringing together the right combination of detailed drawings, relay setting/programming, digital communications, and documentation to deliver successful and repeatable projects.
