Power restored to most of Puerto Rico: utility

Power was restored to most of Puerto Rico Wednesday after a major blackout plunged the island into darkness on New Year's Eve, the US territory's electric utility said.

Electricity supply had been restored to at least 1.44 million customers, or 98.3 percent of those affected, by noon local time (1600 GMT), according to Luma Energy.

The power company said preliminary findings indicated a fault in an underground cable may have been the cause of the outage, although investigations continue.
