The blackout occurred minutes before midnight across the country, with citizens taking to social media to report outages. As outages hit major cities, mobile and internet services were also affected.
The energy minister said the power breakdown occurred when the frequency in the national power distribution system (NTDC) suddenly fell from 50 to zero, adding that the matter was being investigated and attempts were being made to restart the Tarbela Power Station and restore supply.
Omar Ayub said he was personally supervising the restoration work and has been periodically sharing restoration updates on his Twitter account.
