Tanzania’s power outages drop by 48% – EWURA Reports
DODOMA: TANZANIA recorded a significant improvement in electricity reliability during the 2023/24 financial year, with power outages dropping sharply, according to the latest performance report from the Energy and Water Utilities Regulatory Authority (EWURA).
The report, launched this week, shows the System Average Interruption Frequency Index (SAIFI) decreased by 48 percent — from 26 interruptions per customer in 2022/23 to just 14 in 2023/24. Meanwhile, the System Average Interruption Duration Index (SAIDI) fell by 64 percent, from 1,536 minutes to 554 minutes per customer annually.
“These improvements reflect strategic investments in infrastructure and strengthened oversight across the electricity supply chain,” said Dr. James Mwainyekule, EWURA’s Director General. “Consumers are beginning to feel the benefits of a more stable and responsive power system.”
EWURA attributed the improvements to upgraded transmission and distribution networks, reinforced substations, and the commissioning of new generation projects, including early phases of the Julius Nyerere Hydropower Project.

Power reliability has been a long-standing concern for Tanzanian households and industries. Frequent outages have historically disrupted businesses and impacted service delivery in sectors such as health and education.
At the launch event in Dodoma, Deputy Prime Minister and Minister for Energy Dr. Doto Biteko praised the utility sector’s performance and emphasized the government’s commitment to ensuring uninterrupted electricity nationwide. “We are committed to ensure energy services are reliable, efficient and accessible to every Tanzanian,” he said.
The EWURA report positions reliability improvement as a critical step toward supporting industrialization and sustainable development under Tanzania’s Vision 2025.
