IEEE Spectrum's Continuing Coverage of the Blackout of 2003



Darkness Falls: A Timeline of the Blackout of 2003

A new account of the events that led to the cascading outages of 14 August has been prepared by a U.S.-Canadian expert team.

Toward a Better-Managed Grid

Speakers and exhibitors at an IEEE meeting in Dallas, Texas, drew attention to proven and new tools that could help make the U.S. grid systems much more robust.

Five Technologies to Keep Blackouts at Bay

Hardware that is available or soon will be available includes superconducting transmission cables, energy storage devices, fault-current limiters, high-voltage transmission systems, and semiconductor-based controls.

What Is the Grid, and How Does It Work?

Electric power is transported over long distances at high voltage, and then is "stepped down" to lower voltages at for distribution to businesses and residences.

IEEE Advises Congress

The volunteer-driven, policy-advising arm of the Institute of Electrical and Electronics Engineers, known as IEEE-USA, gave testimony to the U.S. House Energy and Commerce Committee on the causes and implications of the 14 August blackout. Among other things it called for mandatory reliability rules, clearer regulatory boundaries between the U.S. and state governments, better regional transmission planning, and grid designs that would limit the impact of failures. It also recommends measures to prompt grids to break into self-contained "islands" under emergency conditions. To see the full testimony, go to the IEEE-USA Website.

System-wide Problems Recognized in First Blackout Diagnoses

A lot of redundancy is built into electric power systems, and hardly ever will just one failure cause major problems. Like all major cascading blackouts, the great Northeast-Midwest blackout of August 2003 was the result of many factors--technical, institutional, and political.

Background to the Blackout

Power engineers, IEEE members, and the Spectrum reporters and editors who cover power and energy have been sounding the alarm about grid problems and potential cascading failures for nearly a decade.
