New system trains good grid operators with bad data

Power grid operators now have the ability to train like pilots, with simulators providing faulty readings designed to throw them off. Such misleading data and resulting loss of "situational awareness" was identified as a major cause of the August 2003 blackout – which cost the country between $4 billion and $10 billion. Better training to identify and resolve bad data was one recommendation in the final report on the August 2003 blackout.
