In Tanzania off-grid electricity is mainly supplied by diesel generators. This causes harmful air pollution and leads to high power generation cost. Contrary to that renewable energies can provide affordable and environmentally sound power. This paper indicates that a potential of at least 22 MW is available for upgrading isolated diesel grids to hybrid grids. The electricity is supplied by state-owned utilities and private cooperatives, representing two contrary business models. A geographic analysis is developed in order to localize isolated diesel grids. Furthermore, detected diesel grids are analyzed in terms of installed capacity, operators and tariff structure.With rising fuel prices, it is expected that upgrading with renewable energies will become the most competitive option for rural areas of Tanzania.
