We spoke to one of the engineers who is contracted to Edenorte and has been here a few times to 'fix' things and he confirmed the unusually long outage was due to a fault with a generator in Puerto Plata.
He said he hoped power would be restored by noon - actually came back on about 2.20 pm and, as yet, has remained on although one of the scheduled outages today for this circuit was from 2 pm - 7 pm.
