Profound blackouts have sticken Venezuela after sabotage at Guri dam's Simón Bolívar hydroelectric plant (archived). The dam, originally built in the 1960's has been continually upgraded through its life to a generating capacity of more than 10,000 megawatts. A portion of the complex's power output is normally exported to Colombia and Brazil. At this time it is uncertain whether the sabotage was carried out by a stuxnet type attack or by the other guys, but terrorism carried out by a rogue state leads the list of possible causes.
Of course, these "humanitarian interventions" have always tended to be very destructive and expensive for the humanitarianly aided (archived).
