The power outage, the second in two weeks, affected eight of the country’s 10 provinces, according Energy and Water Development Minister Dora Siliya.
“I wish to confirm that all parts of the country off electricity supply except for Southern and Western Provinces supplied by Victoria Falls Station,” she said on her Facebook page.
While the cause of the power outage had not yet been established, the Zambian minister said expert suspected that the fault could have occurred at a substation in Lusaka, the country’s capital which affected generators at Kafue Gorge Power Station and the Kariba North Bank Power Station which supply power to most parts of the country.
But Henry Kapata, the spokesperson for the power utility, Zesco Limited, said investigations had been launched to ascertain what caused the system disturbance.
The official further said power had been restored to six out of the eight affected provinces by Wednesday morning.
On December 11, Africa’s second largest copper producer experienced the same problem after the two power stations at Kafue Gorge and Kariba North Bank had a fault during importation of power.
