Zimbabwe’s prolonged power shortage is set to worsen after the entity that manages southern Africa’s biggest dam ordered suspension of electricity generation at its main hydro plant because of a water shortage. In a letter dated November 25 and seen by Reuters, the Zambezi River Authority (ZRA) told the Zimbabwe Power Company that the Kariba South hydropower station had used more than its 2022 water allocation and that the Kariba Dam’s usable storage was only 4.6% full.
