-More than 2 billion people worldwide have no access to electricity, with 99 % of these people residing in developing countries. About 80% of them live in rural areas. In Nepal 56% of the population has access to electricity (49% in the rural areas), but with up to 16 hours of load-shedding in the national grid. This study has been done to show whether the use of individual renewable energy technologies have socio-economic benefits.

 The main idea was to upgrade diesel mini-grids with renewable energies. This upgrade has many advantages such as:
 *Lower power generation costs
 *Lower fuel dependency

Per capita energy consumption is 95 units, which is 8 times less than the national average. The reasons for this are attributed to Insufficient supply and high transmission & distribution losses (51%). Bihar clearly is the state with the highest population density, wherein most of the other states have no access to electricity which causes a huge demand-supply gap. These factors among others have led to strong market opportunitys for off-grid energy solutions. The government in Bihar has made some changes in its laws which have led to the emergence of enterprises in various sectors as well as the improvement of infrastructure.

The installed capacity of electricity power generation is more than '''950 megawatts (MW)''', where 60.5% of it is renewable energies (mainly hydropower). Many mini-grid diesel generators are installed. These have high power generation costs due to the price of diesel, transport costs and low efficiency.
