Further, one of GPL’s second largest units, a 7.8 MW, is back in operation after being unavailable for planned maintenance,” GPL informed.While this cable has been renewed, a second submarine cable which was damaged by another vessel is also in the process of being fixed.The damaged 69 kV cable which rests along the upper Demerara River within proximity of Craig, East Bank Demerara, was dislodged by a barge sailing along the Demerara River.GPL said it is working closely with the contractor to complete the repairs as quickly as possible and to have the cable back in operation soon.last_img
