Solar and wind energy potential assessment for Razavi Khorasan Province in Iran

Abstract

This study aims to evaluate the solar and wind energy potential across Razavi Khorasan Province, Iran, with a specific focus on the Khaf region. A preliminary assessment of mean solar radiation, mean wind speeds, and Weibull distribution parameters was conducted for different towns and zones within the province. The findings showed that Khaf has favorable characteristics for further analysis. The solar and wind energy metrics examined include global horizontal irradiance, clearness index, wind rose patterns, and turbulence intensity. At a height of 40 m, Khaf’s wind power density reached 1650 W/m², indicating exceptional wind energy generation potential. Additionally, Khaf received an average annual solar radiation of 2046 kW·h/m², representing significant solar energy potential. Harnessing these substantial renewable resources in Khaf could allow Razavi Khorasan Province to reduce reliance on fossil fuels, improve energy sustainability, and mitigate climate change impacts. This research contributes an in-depth assessment of Razavi Khorasan’s solar and wind energy potential, particularly for the promising Khaf region. Further work may examine optimal sites for renewable energy projects and grid integration strategies to leverage these resources.
