    Micro Hydro Project: an option for development of Rural

    Areas

    Energy is basic necessity for survival. It is one of the most essential factors for economic development.

    Basically energy is used for lighting and power. In rural village it is derived from different sources such

    as kerosene, diesel, biomass, candles etc for lighting purpose. Fuel burning lanterns are the most

    common alternative of electric lights, which are considered to be a source of respiratory disease. Some

    of the houses use torch lights and dry cells.

    Micro hydro is an attractive choice for electricity generation in rural areas or undeveloped communities

    where grid supply is not available. Micro hydro project is a pioneering electricity generation system

    designed to cope with the lighting demand of houses in rural communities where national grid isnt

    available. It is superior system for that community where investment cant be afforded for the large

    scale hydro and connection of national grid isnt possible for many year but they need energy to develop

    communities.

    The micro hydro system is designed to provide

    electricity by using the water resources available in the

    local areas. By taking the advantages of head and flow,

    water is used to generate electricity. Micro hydro

    system is built with technology and materials that is

    found in local market. It consists of set that consists of

    synchronous generator; turbine and penstock pipe.

    Due to the availability of these components as well as

    the technicians, installation of the project is cheap.

    Before the development of micro hydro project there

    was a lot of consumption of fossil fuel such as kerosene, diesel for lamp and operation of agricultural

    processing mill. Some of the houses used Chinese torch lights and dry cells for lighting purposes. There

    was consumption of 45 liters of kerosene per year and 48 number of dry cell per house, now this has

    been reduced to in number and also saves the money that were being invested in these materials. There

    was excess use of wood for cooking purpose and Jharo for lighting which was not the best solution for

    lighting due to its hazards including environmental and health problems. They were not able to work at

    night; student had to study in smoggy kerosene lamp. As a result, they were living an uncomfortable life.

    This had direct and indirect effect on their health, reduced their work efficiency and led a life with lower

    indicator of human development.

    After the development of micro hydro projects, the

    consumption of fossils fuel has drastically reduced

    and use of wood has also decreased. There is an

    establishment of agro processing mill such as

    grinder and other local industries such as lokta

    processing, carpentry, bakery, poultry farm and

    cold store for the preservation of vegetables and

    fruit for sending to markets which has created the

    employment in village and agro processing mill has

    provided facility for people to grind their product

    Until, MHP they have to walk long distances or they have to pay high rate for grinding the product in

    diesel operated mill. It has also saved the time of the people. Local industries have been increasing and

    people have been establishing electronics shop, computer institute and hotels which have provided job

    for people.

    There is an operator for running the plant and maintenance of the power plant. The establishment of

    plant has also provided job to some people. School of that are now upgrading their school and

    providing students computer education and other facilities to compete the student with city area.

    People are watching TV which has also help them to see the world and other development in the world.

    Development of Micro-hydro project has made the rural areas life a simple manner.

    The life standard of people in that area has increased

    and it helps them increase income generation in

    household level. Success of this project has now

    become one of the factors to boost up the villagers

    lifestyle. They use electricity for lightning purpose

    and communication purpose. After the success of

    this project, students have opportunity to read at

    night in clean environment. People are now more

    engaged in different works for promoting their

    source of income such as in agriculture product and

    other locally available product etc. They are able to

    do their work at night time .The source of income

    and standard of life has been improved. People are now more conscious and aware of utilizing

    electricity; they are now in search of creating more micro hydro project in the vicinity of that area. It

    helps to preserve the deforestation of forest.

    The maintenance cost of the project is somehow problem in that area but if some people take trainings

    related to the plant then it will be benefit for villagers. They can get knowledge about how to run this

    system properly and how to repair it when there is some fault or problem. This will create opportunities

    of job for some people. He/she will look after the system and they dont need to hire other technician

    for simple problem, which also reduces the cost for maintenance. It also helps them to not to depend

    on other people for any simple maintenance and repair.

    Thus in the developing countries micro hydro can play vital role in the development of rural

    communities. It is a better alternative for the area where national grid has not been available. The

    development of new technology and mini grid concept can help micro hydro for the long termsustainable.
