Several RETs have attained commercial maturity for the implementation of rural electrification projects, and there is also a wealth of past experience as well as new experimentation of business models that could ensure the long-term sustainability of such projects. That would allow service providers to conduct cost-benefit comparisons of all options available and to choose the one that is the most economical, suitable to local resources and adapted to the expected demand. The analysis must also consider whether grid extension is a more appropriate electrification method for a given location. The analysis of all parameters should be conducted free from constraints regarding a predetermined technology choice (technology neutrality), and should strive to utilize as much local content as possible with the aim of maximizing trade, economic and investment benefits.
