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 Unsatisfactory Moderately Satisfactory Overall Implementation Progress (IP) Moderately Unsatisfactory Moderately Satisfactory Overall Risk Rating High High Implementation Status and Key Decisions The current closing date remains February 28, 2025. Overall project implementation remains behind schedule, with cumulative delays estimated at three years, primarily driven by initial procurement and mobilization delays, unforeseen geotechnical conditions, and project management capacity limitations at the ZRA. The COVID-19 pandemic has also affected the pace of implementation. ZRA continues to work with all project stakeholders to advance the works and improve project performance. The project has also been restructured to reallocate funding across project components and increase support to the project implementation unit. 6/27/2022 Page 1 of 6 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 -- Substantial Substantial Sustainability Fiduciary -- Moderate Moderate Environment and Social -- High High Stakeholders -- Moderate Moderate Other -- Moderate Moderate Overall -- High High Results PDO Indicators by Objectives / Outcomes Number of people benefitting in the project area through risk reduction and avoided disaster IN01163449 ►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 04-Mar-2022 04-Mar-2022 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 IN01163448 ►Emergency Preparedness Plan adopted and operationalized (Yes/No, Custom) Baseline Actual (Previous) Actual (Current) End Target Value No No No Yes 6/27/2022 Page 2 of 6 The World Bank Implementation Status & Results Report Kariba Dam Rehabilitation Project (RI) (P146515) Date 27-Feb-2015 04-Mar-2022 04-Mar-2022 28-Feb-2025 Measures overall outcome in securing the safety of Kariba Dam through the restoration of operational curve governed by EPP.
