The power cuts will add to mounting public anger against President Emmerson Mnangagwa’s government as Zimbabweans grapple with an economic crisis that has seen shortages of U.S. dollars, fuel, food and medicines as well as soaring inflation that is eroding earnings and savings.

The Zimbabwe Electricity Transmission and Distribution Company (ZETDC) said power cuts, known locally as load shedding, would start on Monday and will last up to eight hours during morning and evening peak periods.

"The power shortfall is being managed through load shedding in order to balance the power supply available and the demand," ZETDC said in a public notice.

Isaac Kwesu, chief executive of Chamber of Mines, which groups Zimbabwe’s biggest mining companies, did not answer his mobile phone when contacted for comment.

Mining accounts for more than three-quarters of Zimbabwe’s export earnings and any power cuts in the sector will affect production and exports.

In the past, some of the big mines, including platinum and gold producers, have resorted to directly importing electricity from neighbouring countries like Mozambique and South Africa.

Zimbabwe last experienced its worst power shortages in 2016 following a devastating drought.

The southern African nation, which is producing 969 MW daily against peak demand of 2,100 MW, is entering its peak winter power demand season, which will increase electricity consumption.

Minister of Energy and Power Development Joram Gumbo was quoted by a local newspaper saying he would travel to Mozambique this week to try to agree an electricity supply deal with that country’s power utility Hydro Cahora Bassa.
