The national peak power demand forecast is 12,800MW as against the available power of less than 4,000MW. Nigeria has a total installed electricity generation capacity of 8,644 MW. However, the peak generation is much lower at around 4,000 MW. The reasons for the shortfall in power generation can be attributed to the inadequate fuel supply to thermal plants, which constitute over 80% of the installed capacity, hydrological factors for hydropower stations, maintenance outages at power plants, and transmission and distribution outages. Against the available power, there is a peak load shortage of more than 8,000 MW. As a result, the available generation capacity is less than one-third of the total peak demand for electricity. This calls for new power projects to be implemented that are dependable, renewable, and cost-effective.
The Karadunwa River and its tributaries flowing through the project area are dammed at Zobe, now called Zobe Dam. The Karadunwa River flows through narrow formed valleys, deep cut valleys, and partly minor sandy floodplains. The optimum installed capacity of the project is 290.3 kW; the design discharge is 7.51 m3/s for each turbine; and three units of 97 kW capacity each are proposed to utilize the entire range of discharges available from the dam.
The installed capacity of the project of 290.3 kW will be injected into the existing 33kv high-tension line.
A rehabilitate, operate, transfer model was adopted. Hydropower is a clean, efficient, and dependable source of electric power at affordable prices. The technology for small hydro is mature and has been in use for decades. The compact nature of a small hydropower project causes a limited impact on the flora and fauna of the project area, and has no displacement or rehabilitation impact on the human population in the region. Since the dam, reservoir, and structures of the hydropower project are already in place, no incremental impact on the population is expected due to the rehabilitation of the hydropower project. As a result of all the above mentioned there is the need to attract private sector technical expertise and financial resources for the generation and distribution of power to industrial and domestic consumers.
The primary objectives of the stakeholder consultations are as follows: • Ensure that all stakeholders that relate to use of the project or will be affected by the development of the project are identified before design work starts. • Bring together all the people relevant to the development, to create a common vision. The key stakeholders in the development of the small hydropower project are the following: • Irrigation dependent farmers/ other users • Various government departments and agencies • Project Area Commissioner • Local administration • River basin development authority • Land and Revenue department • Employees currently working in the dam and trade unions, if any • Community organizations • NGOs active in the area • Contractors of goods and services.
The Karaduwa River and its tributaries flowing through the project area are dammed at Zobe, now called Zobe Dam. The Karaduwa River flows through narrow formed valleys, deep cut valleys, and partly minor sandy floodplains. From the studies, it was found that the optimum installed capacity of the project is 290.3 kW. As the design discharge is 7.51m3/s for each turbine, three units of 97 kW capacity each are proposed to utilize the entire range of discharges available from the dam. The electricity from the proposed 290.3 kW will be injected into the existing 33kV high-tension line located at 350m by means of LILO arrangement.
