The Jamaica Public Service Company (JPS) has begun to restore electricity to Jamaicans following an all-island power outage on Friday night, according to energy minister Daryl Vaz.

Vaz, in a statement late Friday, described the blackout as “unacceptable”.

He said he has been advised by the leadership of the JPS that all power stations are being restarted with a view of having electricity restored to the entire island on a phased basis overnight into Saturday morning.

The energy minister has demanded a full report from the JPS within 24 hours including an outline of what caused the power outage and will update the nation accordingly.
