Zimbabwe - Batoka Hydro Project
About this project
The Batoka Gorge Hydro Power Project is a $4.5 billion investment conceived in 1992. The project is being conducted by the Zambezi River Authority (ZRA), which is a binational agency jointly owned by Zimbabwe and Zambia. They have the mandate to manage all development on the Zambezi river. The project is to be implemented on a Build-Operate-Transfer (BOT) model. The ZRA conducted a procurement process against which PowerChina International alongside GE as the equipment supplier was awarded the project to Design, Build, Finance and Operate the Batoka Hydro Project The recommended option for the Batoka Gorge HES is a 181meter high, 720-meter long roller compacted concrete (RCC) gravity arch dam with two surface power stations on either side of the river, each with a total installed capacity of 1,200 megawatts, giving a total installed capacity of 2,400 megawatts. At the full supply level of 763 meters above sea level, the reservoir is estimated to store 1,392 million cubic meters of water and have a surface area of 25.6 square kilometers. No resettlement is envisaged for the dam or reservoir, which is fully contained within the gorge, and would be operated as a run of river scheme. The hydraulic backwater effect has been evaluated against the dam height and generation capacity to understand the implications of different options and explore a range of measures to balance different interests.
