Principle Advisor

Geofrrey Chan

Former Chief Engineer of HK Electric Company

Geoffrey Chan never tires of dealing with electrical power. For more than three decades he worked for the only Power Company serving the Hong Kong Island. Chan, as the former chief engineer, was responsible for the design, installation, operation and maintenance of the titanic yet congested power grid. He is among the very few in Hong Kong who know the local grid best. He also fulfills his dream of teaching the younger generation with his intimate knowledge in electrical power. It is our honor to have Chan as our Engineering Consultant and let him take charge of our Shadow EV Charging project.
