The Zimbabwe Electricity Supply Authority (ZESA) says electricity has been restored to most of the country’s major supply points following a nationwide blackout caused by a fault on a key transmission line on Sunday evening.
In an update released on Monday night, the power utility said the outage was triggered at around 1824 hours after a major electrical fault developed on the Warren–Alaska 330kV transmission line. The incident disrupted interconnections with neighbouring regional power utilities, resulting in voltage instability and a loss of local electricity generation.
ZESA said restoration efforts began shortly after 1900 hours, with power imports from South Africa’s Eskom, generation from Kariba Power Station, Mozambique’s Hydro Cabora Bassa and Hwange Power Station Units 1, 2 and 3 playing a key role in stabilising the national grid.
According to the utility, electricity had been restored to most bulk supply points across the country by 2200 hours.
However, ZESA said work is continuing to fully restore the system, with technical teams focusing on synchronising the remaining generating units at Hwange Power Station and carrying out repairs at the Warren Substation, which supplies parts of Harare.
The utility apologised to customers for the disruption and thanked stakeholders for their patience as engineers continue working to restore normal operations in the remaining affected areas.
The blackout left homes, businesses and essential services without electricity for several hours, with power supplies gradually returning in different parts of the country as restoration work progressed.
