Abstract
The purpose of this article is to evaluate the commercial use of different solar thermal power technologies in the northern part of Cameroon. For this, a techno-economic study highlighting the design of each technology using various capacities of the studied plant. The main objective was to carry out, technical, economic and financial parameters able to attract investors for the use of such kinds of technology to generate electricity in these provinces [G1] having a good direct normal irradiation estimated at 2145kWh/m2/year and meet at the energy demand of population living with less than 10% electrification rate in rural area. During this study, we considered some technical paramet[G2] ers as total annual DNI received by solar field, Field thermal output, thermal system transfer rated, overall energy efficiency and yearly electricity production. The last parameter was a key parameter for techno-economic analysis of the studied system.[G3] Some parameters as the payback period (PBP), internal rated return (IRR), net present value (NPV) and levelized cost of electricity (LCOE) have been found out during the economic analysis. The bonus carbon can be allowed to a company because of the good electricity generation has been applied during the calculation of these parameters. Other parameters as the initial investment and incentives from the government or financial named in this study have been considered also. The [G4] environmental and social impact assessment (ESIA) related to this purpose give a priority to criteria as grid, land and water access and use for electricity generating. Then, the ESIA study has been considered as a key parameter for Multi-Criteria Decision Maker. The studied systems had various range capacity starting from 5 MW to 100 MW and their analysis in the sub-Saharan region[G5] shown that, the cost of installed kW for concentrating solar technologies (CST) varies between 4550 – 6745 US Dollar , 5240 – 9365 US Dollar and 5100 - 6290 US Dollar and the levelized cost of electricity per kWh varies between 10.22-13.22 USD cents, 11.07-19.81 USD cents and 14.63-15.6 USD cents for Parabolic trough collector(PTC), Solar Tower (ST) and Linear Fresnel (LF) respectively. The solar tower technology can't be efficient compared to other techniques for the thermal power plant (TPP) under 10 MW[G6] [G7] [G8] e due to the initial investment. It important to add this, the cost of installed kW in the sub-Saharan region is higher[G9] than order region because of transportation fees, the lake of solar thermal manufactures for insulation and piping system, metal structure and expertise related to total indirect cost such as engineering procurement construction and advanced ESIA services in this area. The support of financial institution through CER/TAX and a similar approach in addition to existing subvention[G10] [G11] s for such technology can decrease considerably both payback period and feed-in-tariff (FİT) price of the studied system and contribute to developing the sector [G12] by creating an attractive market for investors.
