The Tedzani Hydroelectric Power Station, also Tedzani Hydroelectric Power Complex, is a complex of integrated hydroelectric power plants across the Shire River in Malawi. It has installed capacity of, with four power stations adjacent to each other, sharing some of the physical infrastructure and electro-mechanical connections.[1]
The electricity generating complex was developed in stages, with the first phase Tedzani I, completed in 1973,[2] and the most recent, Tedzani IV, which achieved commercial commissioning in May 2021.
The power stations of this electricity-generation complex are located across the Shire River, in Chikwawa District, in the Southern Region of Malawi, approximately 7km (04miles), downstream of the Nkhula B Hydroelectric Power Station.[1] This is approximately 65km (40miles), by road, north-west of Blantyre, the financial capital and largest city in the country. The geographical coordinates of the power stations of Tedzani Hydroelectric Power Complex are: 15°33'34.0"S, 34°46'38.0"E (Latitude:-15.559444; Longitude:34.777222).
The first to be developed, Tedzani I was brought online in 1973. It consists of two turbines, each with a capacity of, bringing the total capacity at this power station to .[2]
Completed in 1977, Tedzani II has two power-generation units of each, bringing capacity at this power station to .[2]
Tedzani III was the third power station in the complex to be completed, coming online in 1996. It consists of two generators of each, bringing capacity at this power station to .[3]
In July 2017, the Electricity Generation Company Malawi Limited (Egenco) signed agreements with the Mitsubishi Corporation and with Calik Enerji, to build Tedzani IV. The power station was built with a US$52 million grant assistance obtained from the Japanese International Cooperation Agency and a US$4.8 million equity investment by the Malawian government (total US$56.8 million). Commercial commissioning was achieved in May 2021.[4]
