- We assess the sustainability of rural electrification in Manica Province, Mozambique, focusing on different alternatives for mini-grid and off-grid power supply. The qualitative assessment considers four dimensions of sustainability, namely environmental, socio-cultural, economic, and institutional. We argue that small-scale hydropower is the most sustainable alternative for off-grid or mini-grid solutions in rural Manica Province with good possibilities to scale up this to the major parts of rural Mozambique. The investigation shows that social acceptance for small-scale hydropower is high. Environmental sustainability of small-scale hydropower is higher than for PV systems. To speed up the electrification process, efficient rural electrification has to connect policy to local scale and institutional strengthening. The legislation needs to be improved, and there is a need for better institutional coordination for hydropower mini-grids’ regulation. Along this line, a national framework to support small and independent power producers is necessary.

- UN Sustainable Development Goal (SDG) 7 states that access to affordable, reliable, sustainable, and modern energy should be provided for all by 2030. Mozambique is one of the poorest countries on earth but has abundant supply of energy resources. The electrification rate, however, has been slow. Rural electrification is hampered by lack of basic infrastructure, institutional barriers, and low ability and willingness to pay for energy services. Thus, there is a general gap between electricity supply and demand. In view of this, the present paper investigates supply and demand of electricity for a typical rural case study area in Mozambique. We suggest a nexus approach to improve water, energy, and food security initiated at a local level. Households in the investigated case study area can be connected to a mini-grid hydropower system that allows for energy production to 80-200 households. To increase the economic profitability of the mini-grid hydropower system we suggest including small-scale industry. For the studied rural village, this would be constituted by a small-scale factory for milling of corn and other cereals. Electricity produced can thus be used for food processing but also for pumping water supply to households for domestic use and small-scale irrigated farming lots. The results indicate that the villagers have a real payment capacity of between 8 and 19 USD per MWh of generated hydropower. Benefits of rural electrification are direct. It contributes to improved living conditions for households and provides better nexus security and sustainable development within healthcare, education, and small-scale business development.

- Hydropower energy is one of most promising clean energy technologies, however this energy technologies has many challenges if compere other renewable energy for example Biomass, solar, wind energy, has high capital investment cost. In Mozambique, access to conversional energy in form of electricity has been limited to most of the rural population. The objective of this investigation research is to analyze the Chua Micro-Hydropower Plant exploration in Manica district in Mozambique and to examine the possibility of increasing energy production. The current total installed power generation capacity in Mozambique is about 939MW. Hydropower contributes 561 MW, making a contribution of 61%, oil contributes 27%, and natural gas 12% of the total electric grid generation in Mozambique (C) 2015 The Authors.

- Hydropower is a renewable energy that expected to be affected by persistent climate change in Mozambique. Variability of climate e.g. temperature and precipitation will contributors to future shortage of energy from renewable energy production especially for hydropower and biomass. This research reviews the impacts of climate change on the productions of hydropower in Mozambique. Furthermore, a statistical methods using regressions analysis was used to evaluate the future climate scenario. The result showed that the average temperature in first 10 years was 25.4°C and last 10 years was 26.3°C; this means that the gradient of temperature was 0.88°C. The temperature was increasing significant especial the between October-March in rainy season and coincident is summer season. Also the result showed that climate change will cause increased variability of precipitation and create drought which is pre-conditions problems for decreasing hydroelectric generation in Mozambique. With frequency drought, flood combining with trend of precipitations, Mozambique is one of the most vulnerable countries of climate change. It was concluded that Mozambique hydropower productions will have to face challenging future.

- The impact of climate change on the production of hydropower in Mozambique is reviewed and regression analysis is applied to evaluate future climate scenarios. The results show that climate change will cause increased variability of precipitation and create flooding that can damage infrastructure such as hydropower dams. Climate change can also cause drought that will decrease surface water and reduce hydroelectric generation in Mozambique. Electricity generation is to a major extent performed through large-scale hydropower in Mozambique. To fulfill the sustainable development goals (SDGs) and an increased demand for electricity, several large and many small hydropower projects are planned and were built in the country. The economic lifetime of a hydropower plant is typically 100 years, meaning that the hydrologic regimes for the plants should be evaluated for at least this period. Climate change effects are rarely included in present feasibility studies. Economic implications associated with climate change phenomena are higher in Mozambique than in neighboring countries as its future electricity demand to a large extent is forecasted to be met by hydropower. The large hydropower potential in Mozambique should as well be considered when investing in new power plants in southern Africa.
