**5. Conclusion**

This paper has extended the rating model based on the standardized risk management procedure (SRMP) developed by Steurer et al. 2017 (for more information see [6]). The SRMP approach is applied for the mini-grid in Tsumkwe, Namibia. The findings result in an assessment of the mini-grid in Tsumkwe with a moderate level of risk. Important for the strategic management of the mini-grid are the identified strengths and weaknesses supporting long-term risk management. In this case, there main potential is given in the fields of technology and education. Reducing the share of diesel would lead to improved earnings. Further, a wellorganized replacement process is needed to ensure long-term commercial profitability. Particularly, there is evidence to expose the true costs for off-grid electricity distribution as well as to issue a central guideline for particularly off-grid tariff setting. Developing productive use cases to boost and restore the local economy is, furthermore, crucial, which, however, needs to be complemented with comprehensive training offers targeting both operating personnel and the population.
