Failure in high-voltage cable causes two-hour power cut across Gibraltar

Published by GBC News

A widespread power cut on Wednesday was due to a failure in a high voltage cable which provides power to the LNG terminal facility at North Mole - which then interrupted the gas supply to the engines.

The Electricity Authority says its ability to restore power as promptly and safely as possible was then delayed by a systems communication problem, compounded by the need to manually isolate the fault.

The power supply to the LNG terminal was restored once the high voltage grid was reconfigured, with the engines resuming the combustion of natural gas. It took roughly two hours to restore power across all of Gibraltar.

The power cut also saw an Easyjet flight from Gatwick temporarily diverted to Malaga, although it did return to Gibraltar once the airport reopened. Two flights, to Heathrow and Manchester, were also delayed.

A spokesperson for the Government told GBC it understands that the Air Traffic Control standby generator did not work. Navigation service provider NATS said the issue was widespread and not air traffic control related.

For its part, the Ministry of Defence told GBC it is working with its contractors to understand why the backup system did not come on stream immediately.

It says its team worked at pace out to restore the power supply so normal service could resume at the airport as quickly as possible.
