The earthquake damage experienced by electric power systems is briefly reviewed. Low cost methods for improving the seismic response of five categories of equipment damage are discussed. Securing substation transformers prevent catastrophic losses due to transformers falling from elevated pedestals, and the failure of lighting arrestors, bushings and control cables due to lack of slack in interconnections. Securing substation and power station batteries to their racks and the racks to their foundation prevents the serious consequences of their loss. Securing computers can prevent damage and disruption due to their loss. Properly supporting ceilings in control rooms can prevent damage and disruption caused by restriction in their operation. While securing circuit breakers may reduce damage, improved design, materials or installation methods may be required.
