Principal capital changes are linked to the following: Civil works: the development of engineering maturity and identification of new scopes to the project resulted in increases in civil quantities (concrete, rebar and formwork) and the corresponding rise in the installation costs. These changes relate to the water storage reservoir, the water abstraction pipeline, selected major equipment packages and equipment interfaces. More detailed information will be given once the final engineering study is complete by mid Fourth Quarter-2023.
