What will happen in the event of a major earthquake?
Eastshore will be designed to meet the most rigorous Seismic Zone standards in the CaliforniaBuilding Code. The most significant concern associated with a major earthquake is strong ground motion. The Eastshore equipment will be anchored and supported on foundations designed to withstand the strong ground motion associated with a Seismic Zone 4 event. Consequently, the facility is not expected to experience significant damage in a major earthquake. If Eastshore were operating during a major earthquake event, it is possible that the strong ground motion would trip the plant into an automatic and orderly shutdown. Immediately following the earthquake, Eastshore should be capable of rapidly restarting and would likely be a readily available power supply that could be called upon to operate in the event less earthquake-ready facilities are forced off-line for extended periods. The Eastshore tie-in at the local 115 kV distribution voltage also offers PG&E the advantage of being able to supp
