List of thermal power station failures
This list is concerned with severe and abnormal power outages which caused major power failures due to damage to a single thermal power station itself or its connections which take a significant amount of time - months or years to repair. Whilst any electric grid is vulnerable to instability after the loss of a large generating source or transmission line, this can generally be dealt with without serious inconvenience to customers.
