The Mambilla Hydropower Project Is Of Strategic Importance To The Economic Development Of NigeriaByProf S Mustafa
Energy supports almost all human activities and is the backbone of industrialisation for all nations. Mega industrial complexes, the base of American economic power depend on assured supply of energy, which is why, America, would attempt to secure energy source, at any cost, anywhere in the world. Indeed, many sources of energy are available, ranging from fossil fuels including coal, hydropower, nuclear, winds and tidal waves, solar and geo-thermal sources.
Fossil fuels constitute the largest source of energy in the world but they are expensive to generate and maintain and are not renewable. Where hydropower potential exists, it is always the most preferred energy source mainly because it is cheap to generate and easy to maintain. In addition, its generation takes place in clean and quiet environment. Above all, it is the most easily renewable source. Solar energy, though has the similarities of hydropower, it is very expensive to generate per kilowatt-hour, not readily available in large quantities and has low generation efficiencies.
Towards a planned hydroelectric power development in the country, Zungeru dam construction was to follow Kainji, Shiroro and Jebba dams. Next in line were barrages of low head power plants to be constructed at Yola and Makurdi on river Benue and at Lokoja on the confluence of River Niger. The combined capacity of these four schemes has been estimated at between 2,000- 2,500MW.
Need to construct the Mambilla hydropower projectIn the case of Mambilla hydropower scheme, there were to be series of cascading dams of high head plants which will feed into each other to generate up to 6,000MW of electricity. To realise this important project, there is a need for proper planning due to its large capital outlay. The recent move by the Federal government to engage the services of a Chinese firm to handle the project though late, is proper, if pursued to its logical conclusion. China with over 2,000 dams has more than half the number of dams in the world. Moreover, Chinese engineers approach to dam projects is, generally, very comprehensive, as they try to incorporate hydropower units in almost all water storage structures. These range from flask-size turbines of less than 5KW capacity to mega size turbines greater than 100MWcapacity, depending on the nature of river flows.
With or without the Chinese involvement however, government needs to step up considerably, the process of hydro ad meteorological data collection at the dam sites which had stopped since early 80s when feasibility studies were carried out for the preliminary designs. Indeed, the regimes of the rivers have now changed thus, necessitating a change in the design parameters.
Advantages of harnessing the water resourcesof Mambilla
Should the government decide to engage direct labour in the constructions; considerable job opportunities will be created to ease the current unemployment. Conclusion The present shortage of power in the country would have been avoided if the five hydropower plants including Mambilla hydropower project planned since early 80s have been duly executed. Current emphasis must shift from fossil fuels as they are not renewable and more expensive to generate. One of the advantages associated with hydropower plants include the storage of large volume of water which would have run to the oceans, are now put to multi-purpose uses.
