Ngonyezi Projects has entered into a Non-Consumptive Water Use Agreement with the Zimbabwe National Water Authority.
The purpose of the agreement is to install a combination of 2 000 MWh Pumped Storage Hydro and 300 MW Solar PV.
The location of the installation is Osborne Dam on the Odzi river in Manicaland Province.
“Storage is an essential part of a Renewable Energy Strategy and it is recommended that 30% of the installed Solar PV should be supported by storage,” says Tomas Persson, initiator of the project.
Pumped Storage Hydro (PSH) currently dominates total installed storage power capacity, with 96% of the total of 176 gigawatts (GW) installed globally in mid-2017.
The other electricity storage technologies already in significant use around the world include thermal storage, with 3.3 GW (1.9%); batteries, with 1.9 GW (1.1%) and other mechanical storage with 1.6 GW (0.9%).
Zimbabwe is destined to be second country in Africa with pumped storage, after South Africa.
Ngonyezi Projects is developing PSH projects in more than 10 countries in Sub-Sahara Africa.
