Abstract :
On July 12, 2004 at 12:39 local time, the south part of the Hellenic Interconnected Transmission System (including Athens) was split from the rest of the system and collapsed, driving consumers with a total load of 4500 MW into blackout. Technical information about the causes, the evolution, and the consequences of the blackout are presented in this paper. Some qualitative conclusions drawn immediately after the blackout are presented, as well as the results of further studies, including detailed simulations with corrected data, generator adjustments, and protection considerations
