Power has been restored in South Norwalk after a large outage Monday. 

South Norwalk Water and Electric worked several hours to restore the power throughout the evening. 

The Maritime Aquarium also lost power, with visitors saying the outage interrupted a movie showing at the aquarium's IMAX Theater. 

News 12 also spoke to small business owners who say outages like these can have a negative impact very quickly.

So far, no word on what caused the outage.
