Analysis of Wind Energy Potential as a Vertical Axis Wind Turbine Drive (VAWT)

Abstract

The use of wind energy in rural areas of Indonesia is still limited. This study assesses the potential of wind energy in Sigara Gara Village as a driver of vertical-axis wind turbines. The data used was in the form of secondary wind speed data in 2021 from the Graha Garuda Mas housing complex weather monitoring station at an altitude of ±13 m. Data per second is averaged daily, then compiled into monthly and annual averages. The results show a yearly average of 0.70 m/s with a monthly range of 0.70–0.80 m/s. The value is below the initial operating speed range prevalent for small wind turbines. The power per unit area calculated from this average is very low, making it unfeasible for a VAWT drive. The study suggests higher micro-mapping, or diverting to other sources of NRE that are more suitable to local conditions.
