Kim is an expert in Ontario and interconnected grid operations, with extensive experience and knowledge in the electricity sector. He has held various positions throughout his career, including Vice President of Operations and Chief Operating Officer, Director of Planning and Assessments, Manager of Regulatory Affairs, and Manager of System Operations at the Independent Electricity System Operator (IESO).

He played a significant role in the successful restoration of the Ontario power grid following the 2003 blackout, earning recognition from NERC and the province for his efforts. His retirement from the IESO in 2017 allowed him to continue sharing his knowledge and insights through his role as Senior Counsel at Sussex, where he provides analysis, opinion, and background information on IESO and industry papers, as well as offering guidance to clients on various aspects of the electricity sector. 

Kim's expertise extends beyond his work at the IESO. He has been an active member of various industry-based working groups, including chairing several within the North American Electric Reliability Corporation (NERC), the Northeast Power Coordinating Council (NPCC), and the Canadian Electricity Association. His involvement in these organizations reflects his commitment to promoting reliability and cooperation within the electricity industry. 

Kim's career in the electricity sector began with Ontario Hydro, where he joined their Electrical Operator apprenticeship program in 1978. He gained hands-on experience working in hydroelectric generating stations and large transformer stations. Eventually, he transitioned to the System Control Centre and witnessed the evolution of the industry through the open market transition, the establishment of the Independent Electricity Market Operator (IMO), and the subsequent merger with the Ontario Power Authority (OPA) to form the IESO. 

Outside of work, Kim enjoys family life, the outdoors and all types of sports.
