Developer: Botswana Power Corporation (BPC)


Project details and status: The aim of the project is to extend the country's high voltage grid to the Northwest, Chobe and Ghanzi districts to connect new generation capacities as well as to connect areas that are currently being supplied through cross-border power lines to the national grid.


The project comprises two phases. Phase I involves the construction of the over 500-km-long, 400 kV Morupule B to Maun line via Orapa and the 400/220 kV Orapa and Maun substations; the 220 kV Maun–Toteng line and the 220/132 kV Toteng substation; and 132 kV lines to connect Toteng to Gantsi, Gumare and Shakawe along with associated 132/33 kV substations.


Phase II involves the construction of the 230-km-long, 400 kV Phokoje–Dukwi line, a 400/132/ kV substation at Dukwi, the 289-km-long 400 kV Dukwi–Pandamatenga line, and a 400/330/220/132 kV substation at Pandamatanga; a 220 kV line from Pandamatenga to Kazungula, Lesoma and agricultural development zones and various 220/33 kV substations; and 132 kV lines from Dukwi to connect Mosetse and Nata along with associated 132/33 kV substations.


In December 2016, tenders were issued for undertaking construction works for various transmission lines and substations for Phase II of the project.


In January 2018, BPC began construction of the BWP4.8 billion project, each phase valued at BWP2.8 billion.
