In general the power generation capacity in Zimbabwe is too small to meet demand from the industry and private householdings.

Zimbabwe's difficult economic situation causes part of the problems, as coal for power stations may at times not be produced in sufficient amounts.

In the 2010s, the thermal power stations have only been producing small amounts or no electricity due to coal shortages and maintenance neglect.

In December 2015 China agreed to provide a $1.2 billion loan to add 600 megawatts of generating capacity to the Hwange Thermal Power Station.
