The nationwide power outage on December 9 has plunged the entire country into darkness following a lightning strike on the critical Kotmale-Biyagama transmission line, according to the Ceylon Electricity Board (CEB).

In a parliamentary address today, State Minister of Power and Energy, Indika Anuruddha, announced that the Ministry of Power and the Ceylon Electricity Board (CEB) have initiated two separate inquiries into the islandwide power breakdown that occurred on December 9.

The nationwide blackout, triggered by a lightning strike on the Kotmale-Biyagama transmission line, prompted the State Minister to address the Parliament regarding the incident. Indika Anuruddha assured lawmakers and the public that a comprehensive investigation is underway to determine the root cause of the breakdown and to prevent such incidents in the future.

Preliminary reports suggest that a lightning strike hit a key section of the Kotmale-Biyagama transmission line, triggering a cascading effect that led to a widespread blackout.

It took about 6 hours to restored the Sri Lanka’s entire power supply. Global network monitor Netblocks metrics showed a decline in internet connectivity across Sri Lanka.
