A stable, reliable and uninterrupted power supply is one of the basic requirement for economic, social and industrial growth of any nation. Electricity generation capacity in Nigeria is grossly insufficient for the growing demand and there is a need to incorporate small hydropower (SHP) schemes which can be installed in some of the available rivers and streams that are scattered around the country to complement the energy shortage and deficiency. This paper investigated the viability of Elemi river, Ado-Ekiti, Nigeria for a small hydropower scheme as a possible source of off-grid electricity generation to solve the incessant power outages in the three major higher institutions within its catchment. The power demand of the three higher institutions was estimated using questionnaires. The hydrological data for the study area for 11 years spanning 2005 to 2015 were collected and analyzed to determine the flow duration curve (FDC). The mean average velocity of the stream was calculated as 1.21m/s, with average annual flow discharge of 45.9 m3/s, and an average minimal flow of 9.1 m3/s. The average mean estimated hydro power potential obtainable using a diversion scheme is 2.21MW. It was discovered that the yield capacity of Elemi river for power generation with a diversion scheme could not provide the power requirement for any of the 3 higher institutions within its course due to its relatively flat terrain with the maximum derivable head of 8 m. A recommendation for the construction of a dam for an impounded scheme with a minimum gross head of 20 m, which adequately serve the needs, of at least one of the Institutions is made.

Hydro Power Potential

This study is a continuation of the work of evaluation and valuation of the hydro power potential of Small hydropower plants in Guinea. With a total hydroelectric potential estimated at 6000 MW, Guinea generally suffers from a lack of electrical energy, especially in rural areas where nearly 70% of the populations live and less than 15% of this population is connected to the grid. Electricity of the country, which has the negative consequence of the misuse of wood as a source of energy. Hence the need for this study, which aims to assess the hydroelectric potential of the Tokounou waterfall in Kankan prefecture. The main results obtained relate to : the turbine flow rate, the net head, the useful power, the dimensions of the loading basin, the characteristics of the penstock and the choice of turbine. Proposals for the use of the estimated hydroelectric potential have been made, which could improve the energy needs of the locality.

Hydro Power Potential

Malaysia, although having a good number of small to medium hydro power potential sites, has still not exploited all of them. The focus of this manuscript is a feasibility study of the technical viability of power generation from a medium hydropower potential site, the Bukit Merah Dam site, on the Terusan Besar irrigation canal in northern region of Malaysia. This study is carried out using flow data of 2016 from the main irrigation canal of Bukit Merah dam. The data was obtained from Department of Irrigation and Drainage, Perak. The power capacity, yearly energy output of the potential hydro site are studied in this work. Technical analysis of the power output capacity and yearly energy output of three (3) hydro-turbine types (Kaplan, Propeller, and Francis) operable at the same given head and design flow were studied. The study shows that there is a potential capacity of 2.2 MW and an annual energy generation capacity of 7028.47 MWh at a turbine peak efficiency of 92.8% at a design flow of 19.23 m3/s using Kaplan turbine.

Tarbela Dam

The World Bank Study," Water and Power Resources of West Pakistan" [1], is one of the most thorough-going and sophisticated of its type. In re¬reading it we have been struck by a curious argument related to the real benefits to be expected from the construction of the Tarbela dam. It was designed to produce electricity as well as to irrigate land and it was necessary to estimate the benefits that the electricity would confer. One way of doing this was to estimate the saving that would be made by using hydro-power instead of natural gas or imported fuel, for electricity generation. This meant that an appropriate set of prices had to be estimated for Pakistan's supply of natural gas. The way in which this was done was, to say the least, unusual. The relevant passage justi¬fying the approach adopted is as follows:

There exists a wide energy supply/demand gap in Nigeria. The local generation of electricity meets only 31% of the demand of 10000 MW. By contrast, only 39.6% of the total installed capacity for electricity generation is achieved, owing to aging infrastructure, etc. The energy demand/supply pattern and infrastructure critically reviewed thus suggested the need to increase the electricity generation capacity. Furthermore, Nigeria flares 77% of her associated natural gas. Apart from the environmental penalties that flaring represents, in monetary terms, over the 110 years' life of Nigeria's gas reserves, a conservative estimate of the cost of the gas so-flared was $330 billion (based on $20/barrel average price of crude). It was safely inferred that the way forward in meeting the country's energy demand should include a strong element of gas utilization. In previous publications by this group, it was established that while domestic cooking could reduce the flared gas by about 5.4%, a cohesive policy on associated gas use for electricity generation could eliminate gas flaring. For domestic utilization of the associated gas, burner design and safety concerns were identified as the key challenges to overcome. The paper reports the effectiveness of odorizers in leakage detection/ prevention by the local consumers. It also discusses the issue of prevention of gas explosions. The previous cases of gas accidents were reviewed. The safety approaches proffered in the paper identified the relevant areas of research for safe delivery and consumption of natural gas in Nigeria.
