Abstract
This study provides a techno-financial evaluation of two sites in Malaysia: Kudat, located on the coast of the northernmost part of Sabah, the state of East Malaysia with promising wind potential, and Putrajaya in the Klang Valley region with moderate wind potential at high elevations similar to the dominant cities in Malaysia. Three small-scale wind turbines were evaluated, taking into account a nominal electrical power generation below 100 kW. The research is focused on 220 residential households. The software used to perform the evaluation was Hybrid Optimization of Multiple Energy Resources (HOMER). The research novelty is the examination of the non-hybrid small-scale turbines at high elevations for regions with low wind speed, such as Malaysia. Regardless of the wind farms’ financial profit, this study used the net present cost (NPC) analysis in all cases. This research demonstrates the feasibility of small-scale wind turbines mounted at high elevations for generating sufficient energy. The results indicate that in both areas, the RX-20KH3 model is the best option, and the costs of the FH-5000 and RX-20KH3 farms are proportionate for a renewable project. Furthermore, with government support, the WES80 farm could be suitable.

Published: 9 June 2021Due to the exhaustibility and limitations of conventional energy resources, renewable energy sources provide an alternative solution in supplying the essential energy needs while keeping the environment clean
The net present cost (NPC) of each case includes the estimated cost of power generated from the turbine plus power purchased from the grade minus the power sold to the grid
This study demonstrates the viability of small-scale wind turbines installed at high elevations to generate an adequate power level
Summary
Published: 9 June 2021Due to the exhaustibility and limitations of conventional energy resources, renewable energy sources provide an alternative solution in supplying the essential energy needs while keeping the environment clean. Renewable energy sources have grown considerably grown worldwide. They account for 14% of all energy production globally, and it has been predicted that by 2050, 85% of the total energy will be supplied by renewable energy sources [1]. From another perspective, the renewable energy demand has an annual increase of approximately 3.3% [2], making it the world’s most rapidly growing energy source. In the Asia-Pacific region, renewable energy sources are rapidly growing.
