The country’s main power plants abruptly stopped supplying energy before noon, causing all other plants to shut down, according to the state-owned Dominican Electricity Transmission Company. But by mid-afternoon, the system was operating at nearly 30% of its capacity, Energy Minister Joel Santos said.

"Essential services such as hospitals, drinking water systems, mass transit and airports are operating with their backup systems,� he said.

Santos said that the failure was caused by a trip in a transmission line switch, which caused the system to go into protection mode.

A last November was blamed on human error during line maintenance work.
