EAE Scenarios for Clean Energy Solution Providers in Tanzania

This report introduces an updated geospatial database for clean energy solution providers in Tanzania, delivered via the Energy Access Explorer (EAE) software. The publication demonstrates how standardized, open-access data and multi-criteria analysis (MCA) can be used to identify market expansion opportunities and target investments for mini-grids and other off-grid energy solutions in rural and last-mile communities.

• Tanzania faces significant electricity access gaps, with over 30 million people—approximately half the population—lacking basic electricity services. Household connectivity to the national grid is 29% overall, with a stark divide between urban areas (86% in Dar es Salaam and 59% in other urban areas) and rural areas (11%). Solar home systems (SHSs) provide electricity for 32% of rural households.
• The Tanzanian government aims for universal energy access by 2030 using a mix of grid, mini-grid, and off-grid solutions. While a 2018 uniform tariff for mini-grids hindered private development, a 2021 policy change allowing developers to negotiate cost-reflective tariffs with the Energy and Water Utilities Regulatory Authority (EWURA) has made the market more favorable for mini-grids.
• The Energy Access Explorer (EAE) platform for Tanzania now includes over 70 datasets, including a collaboratively developed database of 135 mini-grids across mainland Tanzania. Analysis of this data shows that over 70% of mini-grids are privately owned, and nearly 80% utilize solar PV (55.6%) or hydropower (23.0%).
• EAE utilizes multi-criteria analysis (MCA) to provide decision assistance for energy planners and companies. This allows users to prioritize locations for energy access, identify market expansion opportunities based on population and distance to grid infrastructure, and inform research on system design, sizing, and cost.
