The Hwange Thermal Power Station is the biggest power plant in Zimbabwe with an installed capacity of 920 MW.
It was built in two stages and consists of 4 units of 120 MW each and 2 units of 220MW each. Engineering Consultants, Merz & McLellan, were employed for the design and supervision of the construction of the power station. Construction of Stage 1 commenced in 1973, but was suspended in 1975 due to economic sanctions imposed on Rhodesia. Stage 1's units were commissioned from 1983 to 1986 with Stage 2's units following in 1986/87.[1]
A reliable source of water lies further north, in the Zambezi River. From there, through a 44 kilometre long pipeline, water for the Boilers and Cooling Towers is drawn by both high and low lift pumps to a storage reservoir located adjacent to the station and conveyed by gravity to the station. About 107'000 cubic meters of raw water can be provided per day; while the demineralisation plant has a capacity of 5'420 cubic metres per day.
A 3.5 kilometre conveyor belt brings about 1'750 tonnes of coal per hour from the nearby Wankie colliery open cast mine, and 250'000 tonnes of coal are stockpiled on site. Coal reserves estimated to support 1'200 MW for an estimated 30 years are concealed beneath the vast expanse of the coal mine.
It is owned and driven by the national electricity company ZESA Holdings (Pvt) LTD..
Technical problems due to neglect of maintenance, part replacement and upgrading make the plant prone to frequent production stops. In 2009, Namibia's NamPower made agreements to help ZESA to revive the plant’s capacity in exchange for power deliveries.[2] The extensive problems are however continuing and have even led the government to considering a full close-down of the plant.[3]
