Blackout 2003: "Midwest Utilities Were Warned About Pushing Limits of System"

"Problems on the lines were becoming more frequent, and a series of reports, both by the industry's own quality-control offices and government agencies, described the risks and urged utilities to be more aware of the physical limits of the Midwest system."

"The complexity and magnitude of the power flows, one report by the Federal Energy Regulatory Commission said, could 'overwhelm the electronic and software tools used to model and manage power flows on the grid.'"
