Tanzania is poised for a major energy transformation as the Julius Nyerere Hydropower Project (JNHPP) prepares for commissioning in early 2025. Located on the Rufiji River within the Selous Game Reserve, this landmark project represents a decisive step toward national energy independence and sustainability.
With a planned capacity of 2,115 megawatts, JNHPP stands among the largest hydropower projects in sub-Saharan Africa. Once all nine turbines, each producing 235 megawatts, become operational, Tanzania’s total generation capacity will surpass 4,000 megawatts, strengthening grid reliability and ensuring affordable electricity for homes, industries, and businesses nationwide.
Previously, Tanzania’s energy output stood at around 2,411 megawatts, largely sourced from the national grid. The new hydropower addition will significantly reduce reliance on expensive and polluting diesel generation, helping to stabilize voltage, minimize blackouts, and move the country closer to universal energy access.
Even with this large-scale investment, off-grid solutions such as microgrids remain essential. They play a vital role in powering remote and rural communities, promoting inclusive growth, and enhancing local economic resilience.
Digital transformation is also reshaping the nation’s energy landscape. TANESCO, Tanzania’s state utility, operates over 7,500 kilometres of transmission lines and 67 substations, supported by a modern Advanced Distribution Management System (ADMS). This technology integrates SCADA, DMS, and OMS to enable real-time monitoring, fault detection, and smarter grid management, paving the way for distributed energy resources.
Sustainability efforts are further strengthened through innovations like Schneider Electric’s AirSeT SF6-free switchgear and automation systems. These eco-friendly technologies reduce carbon emissions and enhance grid reliability, especially when paired with microgrids supporting industries, data centres, and essential services.
Tanzania’s progress extends beyond infrastructure to people-centered initiatives. Through Schneider Electric’s Access to Energy programmes, communities benefit from solar-powered products such as Mobiya lamps, Homaya home systems, and Villaya microgrids, which foster local empowerment and inclusive development.
By blending hydropower expansion, digital innovation, and community-driven energy access, Tanzania is shaping a cleaner, more resilient energy future. The JNHPP and accompanying technological advances symbolize the nation’s long-term commitment to sustainability, self-sufficiency, and economic transformation.
Tanzania’s energy vision reflects a powerful combination of progress and purpose building not just electricity infrastructure, but a foundation for enduring national growth.
