Has the Project Development Objective been changed since Board Approval of the Project Objective? No Components Table Name Component 1: Institutional and Project Management:(Cost $70.30 M) Component 2: Plunge Pool Reshaping:(Cost $99.30 M) Component 3: Spillway Refurbishment:(Cost $124.60 M) Overall Ratings Name Previous Rating Current Rating Progress towards achievement of PDO Moderately Satisfactory Moderately Unsatisfactory Overall Implementation Progress (IP) Moderately Unsatisfactory Moderately Unsatisfactory Overall Risk Rating Substantial High Implementation Status and Key Decisions The project remains significantly behind schedule with new delays expected. The implementation and financing arrangements of the project are complex due to the nature of the engineering works (including the discovery of unanticipated ground geotechnical conditions, resulting in design and construction complications) as well as the multiple sources of financing. In such context, robust action is needed to improve decision-making and avoid further delays. Some activities, especially related to recruitment of staff to support the project or contract modifications, have faced significant delays to be completed. The ZRA has proactively managed the impacts of COVID-19 in the project and updated and disclosed the updated Environmental and Social Impact Assessment (ESIA) of the project. 9/21/2021 Page 1 of 5 The World Bank Implementation Status & Results Report Kariba Dam Rehabilitation Project (RI) (P146515) Risks Systematic Operations Risk-rating Tool Risk Category Rating at Approval Previous Rating Current Rating Political and Governance -- Moderate Moderate Macroeconomic -- Moderate Moderate Sector Strategies and Policies -- Low Low Technical Design of Project or Program -- High High Institutional Capacity for Implementation and -- Moderate Substantial Sustainability Fiduciary -- Moderate Moderate Environment and Social -- High High Stakeholders -- Moderate Moderate Other -- Moderate Moderate Overall -- Substantial High Results PDO Indicators by Objectives / Outcomes Number of people benefitting in the project area through risk reduction and avoided disaster IN01027417 ►Number of people benefitting in the project area through risk reduction and avoided disaster (Text, Custom) Baseline Actual (Previous) Actual (Current) End Target Dam break analysis Dam break analysis 3,000,000 people no 3,000,000 at risk from Value complete and EPP complete and EPP longer at risk from failure update underway. update underway. failure Date 27-Feb-2015 10-Feb-2021 10-Aug-2021 28-Feb-2025 Successful completion of the rehabilitation works will improve the safety and remove the threat of risks to Comments: downstream populations Emergency Preparedness Plan adopted and operationalized IN01027416 ►Emergency Preparedness Plan adopted and operationalized (Yes/No, Custom) Baseline Actual (Previous) Actual (Current) End Target 9/21/2021 Page 2 of 5 The World Bank Implementation Status & Results Report Kariba Dam Rehabilitation Project (RI) (P146515) Value No No No Yes Date 27-Feb-2015 10-Feb-2021 10-Aug-2021 28-Feb-2025 Measures overall outcome in securing the safety of Kariba Dam through the restoration of operational curve governed by EPP.
