Tanzania has recorded a strong expansion in national electricity generation capacity, reflecting accelerated investments across multiple energy sources and reinforcing the country’s long-term strategy for energy security and industrial growth.
Presenting the Ministry of Energy’s budget estimates for the 2026/27 financial year in Dodoma, Energy Minister Deogratius Ndejembi confirmed that installed generation capacity has reached 4,522.54 megawatts as of March 2026. This represents an increase from 4,031.71 megawatts recorded in March 2025, marking a rise of 490.83 megawatts within a single year.
The year-on-year growth translates to an expansion rate of 12.17 percent, a significant jump in a sector considered central to Tanzania’s economic transformation agenda. Government officials say the increase reflects deliberate policy actions aimed at strengthening infrastructure and diversifying energy sources.
According to the minister, the expansion has been driven by coordinated investments in hydropower, natural gas, solar, wind, geothermal systems, and emerging energy technologies. This diversified approach is intended to reduce reliance on a single source of generation while improving system reliability and resilience against climate-related disruptions.
The growth in capacity is also closely linked to ongoing efforts to meet rising domestic demand. Tanzania’s population growth, urban expansion, and industrial development have placed increasing pressure on the national grid, prompting large-scale investments in generation and transmission infrastructure.
Energy sector analysts note that the addition of nearly 500 megawatts within a year is a strong indicator of accelerating infrastructure development. It also signals improved investor confidence in the energy sector, particularly as public and private sector participation continues to expand.
Beyond domestic supply, the government has reiterated its ambition to position Tanzania as a regional energy hub within the Eastern and Southern African power networks. With rising installed capacity, the country is increasingly expected to play a stronger role in cross-border electricity trade and regional grid stability.

Minister Ndejembi emphasized that energy remains a strategic pillar for national development, directly influencing industrial productivity, job creation, and social services delivery. He stated that continued investment in large-scale energy projects is essential to sustaining economic growth and ensuring universal access to reliable electricity.
The government’s broader development vision also aligns with expanding renewable energy integration, aimed at balancing environmental sustainability with economic needs. Hydropower remains a dominant contributor, while solar and gas-based generation are gradually increasing their share in the national energy mix.
Despite the progress, experts highlight the importance of strengthening transmission networks and improving distribution efficiency to fully maximize the benefits of increased generation capacity. Addressing grid losses and expanding rural electrification remain key priorities for the sector.
Overall, the latest figures demonstrate a clear upward trajectory in Tanzania’s energy landscape. With capacity surpassing 4.5 gigawatts, the country is steadily building a stronger foundation for industrialization, regional energy influence, and long-term economic resilience.
