Mini Hydro Development by Self Help and Learning Process Approach

Country: Ghana States: Volta Region/Likpe Area/Dayi River Capacity: 200 kW
Year:  Client: Government of Ghana Energy: 
The Kukurantumi micro hydro project was a pilot demonstration scheme implemented through Learning Process approach ( LP) with community participation and funds contributed by the people of  the Likpe area. 

The project was planned with an aim to achieve self sufficiency in water and energy at the micro level. The Volta region was divided into a series of micro regions (MR) with  each MR covering an area of about 50 km and containing a group of villages. The Gross Micro Regional Product (GMRP) of each MR was computed by evaluating the value of goods and services produced therein along with its energy consumption and production potential. 

On the basis of ratios calculated from above, the Likpe Micro region was selected for development of the pilot Self help electrification project. Other neighboring micro regions such as East Buem, Likpe, Gbi, Alavanyo, Nkonya, Jasikan and Santrakofie would develop similarly to form a local grid to provide 5MW through a series of small hydro projects on the Dayi and other rivers flowing in the area.

PROJECT LOCATION

Mini Hydro Committees were formed with each MR providing graduate representative heads. The MR's also provided skilled, unskilled men and women volunteers with requisite construction materials to build the pilot project. The project was supported by the Provisional National Defence Council and the Secretary for Rural Development.

There is scope for implementation on such lines called Learning Process Approach with Self Help in many rural areas so as to electrify remote rural areas where grid extension would be uneconomical. 

RIVER DIVERSION

COFFER DAM CONCRETING

The site  selected at Likpe Kukurantumi on Dayi River is also one of the series formulated for development from the study on Renewable Energy Development studies on Ghana. In the Likpe micro region other sites which could be developed are located at Likpe Abrani, Lolobi, Wegbe, Kudzese and Adofe. 

The Dayi river is perennial and originates in Togo. It flows westward through steep reaches upto Abrani and thereafter becomes gentle and joins lake Volta at Degame. The total river length is 88 miles with catchment of 800 square miles. Several mini hydro projects are possible which can provide cheap power to villages along the river.

A report covering all aspects of the project was prepared and submitted to the Government. It was approved by the Minister for Lands, Natural Resources, Fuel and power and the cabinet.

SURVEYING

The project was constructed by mobilizing the community on food for work basis. Those with basic education were also trained in simple surveys and practical construction aspects. The local people also contributed money. Many organizations also came forward with contributions ranging from light construction equipment to vehicles. The Government of India gave a small 10kW turbine generator set.

MAIN DAM VIEW

The river channel was diverted by means of sandbags and a concrete coffer dam wall was built. This was eventually made part of the main dam. The completed dam creates a lake which is also suitable for water supply, small scale irrigation and fisheries development. 

In 1999, the project report was updated by SECSD with computerized designs and drawings for increasing the capacity to 200kW and implementing the other stages along the river. The projects started with self help can now be executed under blue print approach (BP)  after the rapid initial development through learning process (LP) approach.
