| dc.description.abstract | This study determined the electricity demand for urban residential development initiatives in Calabar, Cross River State, established the technological specifications for hydrokinetic power development for the urban residential development initiatives and assessed the economic viability of the hydrokinetic power infrastructure. These were with a view to promoting the adoption of hydrokinetic power infrastructure needed for the urban residents in Calabar, Cross River State, Nigeria. The study was carried out in three different selected urban residential areas, electricity audits of the selected urban residential development initiatives was carried out to obtain their power loads and total time of use. The data obtained was used to determine the electricity loads and energy demand. The obtained results served as the benchmarks for the design of the hydrokinetic power infrastructure. Data on technological specifications for the development of the hydrokinetic power infrastructure was obtained from journal articles and reports of the Cross River Urban-Rural Authority. The information obtained included the location coordinates, the lengths and widths of the river, and the river flow velocity. The specific location with its coordinates was mapped out using geographical positioning system (GPS). Information on appropriate turbine specifications and allied electrical components such as transformers came from equipment vendors and literature. Technological specifications for an alternate diesel power generation and CO2 emission savings were elicited from the International Energy Agency (IEA). The data obtained was analysed using energy planning and foresight analyses methodology. The economic viability of the hydrokinetic power infrastructure was determined using capital and operations costs, interest rates, and project time duration amongst others. The data obtained was analysed using life cycle and engineering economy analyses. The results showed that 815 housing units in the selected area had 9.2 MW power load demand with projected energy consumption of 51.8 MWh/day. The hydroquest turbine was found to be most suitable for the extraction of hydrokinetic power from the Calabar River. From the design calculations, 128 numbers of the suitable turbine (80kW hydroquest 2.80) were needed to produce the said electricity demand of 9.2 MW. The hydrokinetic requires a total investment cost of forty-one billion, nine hundred and three million four hundred and fifty naira (₦41,903.45 ×106). The investment required an annual operating cost of four billion five hundred and twelve million two hundred thousand (₦4,512.20 ×106). The levelized cost of HKP-based electricity was found to be ₦68.99/kWh at present. Subsequently, the levelized cost of HKP-based electricity for the first year of operation was ₦82.79/kWh. The estimated minimum revenue for the HKP-based electricity project was six billion five hundred and twenty-six million naira only (₦6,526.00×106) leading to investment recovery on the 7th year of 25 years life cycle of the project. The result also indicated that 528 metric tons of CO2 can be saved from the atmosphere over the 25 years life cycle of the project. The study concluded that, the establishment and development of hydrokinetic power plant in Calabar is technologically and economically viable. | |
