WOODBURY - Today marks 10 years since the big Northeast blackout that left 50 million people powerless.

The 2003 power outage spread from Ohio to seven other states, including New York and parts of Canada.

The outage affected more than 100 power plants.

The blackout was blamed in part on trees touching higher-voltage transmission lines.

News 12 Long Island’s Shari Einhorn spoke to LIPA trustee Matt Cordaro, who said the electric system is better off than it was 10 years ago. However, he says a lot more needs to be done to prevent a similar blackout.
