Namibia and Zimbabwe have signed a new 15-year power purchase agreement (PPA) for Zimbabwe to supply Namibia with 80MW. The PPA between NamPower and the Zimbabwe Power Company (ZPC) forms part of ZPC’s strategy to finance expansion of the Kariba South hydropower station. The capacity of the power station is 700MW now, and will rise to approximately 980MW after the expansion. The agreement signed on 16 October will become effective once the existing Zimbabwe Electricity Supply Authority (Zesa) agreement comes to an end early in 2015.
