PROJECT NAME	Tanzania Integrated Irrigation and Hydropower Development Plan
PROJECT COST	7,200,000,000.00
COMPLETION DATE	01/01/2026
PROJECT INFORMATION	Objectives Deliver reliable irrigation water to ~10 million hectares of farmland. Generate clean, renewable hydroelectric power to support rural electrification and agricultural mechanisation. Enhance climate resilience and sustainable water-energy-food nexus. Integration of Hydropower into Dam Infrastructure All large dams in the plan will be designed as multipurpose facilities, combining water storage for irrigation with hydropower generation. Large Dam Locations & Hydropower Potential Rufiji River Basin Dam - Southern Highlands & Coastal Areas - 150 MW Pangani River Basin Dam - Northern Zone & Coastal Areas - 75 MW Great Ruaha River Basin Dam - Southern Highlands - 80 MW Lake Victoria Basin Dam - Lake Zone - 50 MW Malagarasi River Dam - Lake Zone - 30 MW Wami River Basin Dam - Coastal & Northern Zones - 40 MW Ruvuma River Basin Dam - Southern Highlands & Coastal Areas - 60 MW Total Estimated Hydropower Capacity: 485 MW Additional Infrastructure for Energy Production Powerhouses: Turbines and generators integrated at each dam site. Transmission lines: Connect hydropower plants to the national grid and rural mini-grids. Energy storage and management systems: Facilitate stable supply and irrigation pumping demands. Renewable energy hybrid systems: Combine hydropower with solar to optimise energy availability. Type of Hydropower Plants Mostly run-of-the-river with reservoir storage (storage hydropower) to ensure reliable irrigation water supply and stable energy generation. Design must allow water release regulation for irrigation without compromising energy generation. Operational Modes Base load operation: During high water availability, maximise power generation. Peaking operation: Adjust generation based on irrigation demand and grid needs. Water Use and Coordination Hydropower releases are coordinated with irrigation schedules to balance energy production and water supply. Storage dams allow controlled release during dry periods. Minimising evaporation and seepage from reservoirs to maximise both irrigation and power generation efficiency. Auxiliary Systems Control Systems Grid Connection Spillways & Safety Fish Passages Medium and Small Dams (70) Smaller dams and water retention basins to serve local irrigation schemes and farm clusters. Located near small river tributaries and valleys across all zones. Support groundwater recharge and local water availability. Canal and Pipeline Network Primary canals to connect dams to main irrigation hubs. Secondary and tertiary canals/pipe systems to deliver water to farms. Use of lined canals to reduce seepage losses. Incorporate pumps along canals where gravity flow is insufficient. Pumping Stations and Water Control Electric/diesel pumps powered by renewable energy where possible. Automated flow control gates for efficient water distribution. Remote monitoring sensors for water levels, flow rates, and leak detection. Modern Water Management Systems Mobile apps and interfaces for farmers/cooperatives to schedule water usage. Data-driven irrigation scheduling to reduce waste and optimise crop water use.
