(23 December 2019) morning Maltese transmission system operator Enemalta
plc revealed that it suffered an extensive power outage. After further
investigations, the root cause of the issue was attributed to 200 MW Malta–Sicily
which connects the power grid of Malta with the Italian Transmission Network.
Enemalta began effort to restore the power supply started being restored
around 10:04 am with the use of emergency turbines. Electricity supply
was back to normal by around 1pm.
Enemalta has since confirmed that two of the three conductors and all fibreoptic
lines about 30 kilometers from Sicily have been damaged. At the time of
the incident, the interconnector has been loaded with a full load because
there were limitations in the capacity of generating plants in Delimara
The interconnector is expected to take weeks to be fixed, it reducing the
flexibility that Enemalta has at its disposal. The company stated that
this may result in an interruption in the electricity supply from time
to time circumstances.
