Y2K was of great concern to my company due to the programmable chips / computers present in most of the equipment we utilized – such as relays, monitoring and control equipment inside substations, control equipment on the transmission and distribution lines, and remote terminal units in substations connected to the emergency management system. There were serious concerns regarding interconnection points, not just between utilities, but also between computers and equipment. Luckily, after hundreds of hours of preparation, it became obvious early sitting in the control center on New Year’s Eve and watching Australia and Asia and Europe have no problems that this would be a non-event. But that’s ok because you never know and therefore, it is critical to be prepared even when the situation in question turns out to be a non-issue.
