European Power Outage Affects Nearly 4 Million

LCG, Sept. 26, 2003--Early Tuesday evening, southern Sweden and eastern Denmark experienced a blackout that was apparently caused by a failure on a transmission line, and which lasted several hours.

Denmark's capital city of Copenhagen as well as an industrialized area of Sweden were affected by the outage, which was estimated to have affected almost four million people across the two countries. The line that failed crosses the border between Sweden and Denmark.

The economic impact of the blackout was thought to be "very modest", according to an economist with Dankse Bank, Jesper Hansen, who was quoted in Dow Jones Newswires. While some pharmaceutical factories and other industrial facilities were forced to shut down, and nearly all businesses in Copenhagen closed, financial markets remained open, thanks to backup generators. Traffic congestion resulted on roadways, and airlines and rail traffic were temporarily disrupted until power was restored, first in Sweden and next in the islands of Denmark that had been impacted.
