A new generating station designed and built in the early 1990s had been in service for approximately one year when a lightning strike or strikes hit the facility. Numerous instrumentation failures were experienced and multiple cards within the DCS were damaged or destroyed. The damage pattern did not correlate well to known strike points or destroyed instruments. A field instrument destroyed by the strike did not necessarily have its associated DCS input card destroyed. The facility remained offline for several days, with resultant contractual liabilities of over 5 million dollars.
