Accelerating Mini-grid Deployment in Sub-Saharan Africa: Lessons from Tanzania

Tanzania has expanded its mini-grid capacity since 2008 through the small power producers (SPP) framework, now operating over 100 systems serving approximately 184,000 customers. While hydro is the most common technology, fossil fuel systems provide the majority of customer connections. The government has updated regulatory frameworks to better support solar and wind energy and attract private investment, including pegging tariffs to the U.S. dollar and lowering project size eligibility to 100 kW. However, challenges remain regarding cumbersome non-energy regulatory clearances, limited access to local commercial bank financing for domestic developers, and a lack of systematic data on socioeconomic impacts.

• Tanzania's mini-grid sector has grown significantly since 2008, with at least 109 mini-grids currently providing a total installed capacity of 157.7 MW to about 184,000 customers. Between 2008 and 2016, 52 mini-grids were commissioned, adding more than 67 MW of capacity.
• Technology distribution is skewed; while hydro is the most frequent technology with 49 systems, the 19 fossil fuel systems are responsible for almost half of the total installed capacity and 93 percent of customer connections. Solar and wind deployment has been hindered by early feed-in tariffs that did not reflect generation costs, and as of 2016, no solar or wind agreements had been implemented despite a 2015 regulatory revision.
• The 2015 revision of the small power producers (SPP) framework introduced several measures to attract private sector investment: a competitive bidding process for solar and wind plants over 1 MW, a reduction in eligible project size from 1,000 kW to 100 kW, and pegging the feed-in tariff to the U.S. dollar to assist developers with dollar-denominated debt.
• Financial and administrative barriers persist, including a complex planning process that can involve up to 13 steps and months-long delays for non-energy clearances. Local commercial banks are reluctant to lend to domestic developers due to poor documentation and limited funds, meaning most local finance is obtained by foreign-owned businesses.
• Anecdotal evidence indicates that mini-grids foster rural development by enabling new enterprises such as poultry farming and fruit processing, improving access to market information via ICT, and enhancing services in clinics and schools.
