MHP is decentalised, renewable, powerful, and simple technology.
It only takes handful of flow (less than few litres per minute) or a drop only 1 m to build electrical energy with micro hydro. Electricity can be delivered as far as 1 km away into area where it really is being used. If planned carefully and well adapted into the ecological conditions, small hydropower systems create a continuous and foreseeable availability of electrical power when compared to various other minor renewable technologies. The top energy period is during the cold winter months when large quantities of electricity are required. MHP is regarded as to operate as a ‘run-of-river’ system, and therefore water moving through generator is directed back to the stream with fairly small effect on the encompassing ecology. When compared to big hydropower, MHP thus only has just a little unfavorable ecological influence. Bad socio-economic impacts are even insignificant compared. Further advantages feature reasonable distribution and working prices (requires no fuel and just zero-maintenance) and regional implemenation and management. Furthermore, hydropower is a durable and powerful technology; methods typically continue for 50 years or even more without significant new investments.
Moreover, MHP can be considered a cost effective power option. Creating a minor hydro-power system can cost from $1, 000 - $20, 000, depending on site electricity demands and place. Maintenance fees tend to be reasonably small when compared with various other technologies. As a result of the inexpensive flexibility and durability of MHP, building nations can manufacture and apply technology to assist supply essential electrical energy to tiny communities and villages. If MHP plant produces a great deal of excess energy, some energy businesses might buy back electrical energy overflow. In addition, you'll be able to supplement the small hydropower with intake from power grid.

You can find, but several disadvantages that have to be considered. MHP plants need certain website conditions and generally are therefore perhaps not suited to any location. To take full advantage of the electric potential of tiny streams, the right website is needed. Factors to consider tend to be: length through the power resource into the location where energy is needed, flow dimensions (including movement price, output and fall), and a balance of system elements — inverter, electric batteries, operator, transmission line and pipelines. Minimal technical knowledge especially in resource-rich areas might impede hydropower development. Also, the size and circulation of little streams may limit future site growth as the energy need increases. As MHP plants need no reservoir, electricity generation is extremely dependant on an constantly enough river release. In many locations stream size will fluctuate seasonally. Throughout the summer season there may likely be less flow and as a consequence less power output. Advanced preparation and research will undoubtedly be needed to ensure sufficient power requirements tend to be fulfilled. Finally, ecological impacts need to be taken into consideration. The environmental impact of minor hydro is minimal; but the low-level ecological impacts should be taken into account before construction begins. Flow water are diverted from a portion regarding the flow, and appropriate caution needs to be exercised to ensure there will be no damaging effect on the local ecology or municipal infrastructure.
