NORWALK - Five years after the Northeast was hit by the largest power outage in United States history, Connecticut Light & Power is ensuring residents of its preparedness.

A CL&P spokesperson said Thursday, "We're continually working to strengthen our system to ensure reliable service for our customers. It's something we take very serious."

On Aug. 14, 2003, thousands of New York City residents and commuters were forced to make their way home without public transportation. Thousands were stranded on Metro-North trains and portions of southwestern Connecticut were also left without power for days.

No one News 12 Connecticut talked to remembered it was the anniversary of the blackout, but all shared memories of where they were when it happened.

?I was grocery shopping actually,? Bonnie Pomponi, of Norwalk, said. ?It was very scary. Everything went dark in the store ? I thought there was going to be riots and everything, I really did.?

The CL&P spokesman couldn?t say whether the chances of a repeat of 2003 were good.
