On Sunday October 6, 2016, the Guyana Power and Light Inc. effectively completed maintenance on the 69 kV transmission line and structures carrying 11 kV and 13.8 kV lines along the corridor linking the Kingston Power Stations to the Sophia Substation, at 20:00hrs.
During the execution of remedial works, transfer of power from Kingston to Sophia and other substations along the East Coast and East Bank was not possible. Customers along the East Bank Demerara, East Coast Demerara and Georgetown experienced intermittent outages from 08:00 hrs to 20:00hrs, partly due to switching to and from alternative sources of power supply, and capacity shortfall resulting from problems encountered with the boiler at Skeldon which had initially been supporting the grid with over 12 MW.
GPL says that there was an isolated case where power was not restored to customers of Delhi Street, Prashad Nagar on completion of the exercise, due to an unrecognized local fault not directly linked to Sundays’ maintenance exercise. This has since been rectified.
Additionally, there was an interruption in the supply of electricity in Kitty, Kingston, Cummingsburg and Sophia at around 10:00 hrs today as a result of machinery operations within the vicinity of the railway embankment.
