Evaluation of the Gross Wind Energy Potential of Uzbekistan

Abstract

Relevance: optimizing the use of renewable energy sources is one of the pressing challenges for meeting modern energy demands and adapting to global climate change. The assessment and analysis of wind energy potential in Uzbekistan, considering local climatic conditions and wind regimes, provide opportunities to accelerate the country’s transition to “green energy” and enhance its energy security. This study is crucial for developing scientifically grounded strategies for wind energy development.

Aim: to calculate Weibull distribution parameters for wind speed, power density, and energy in Uzbekistan and assess the gross wind energy potential for planning wind energy projects.

Methods: the study analyzed data collected from 77 meteorological stations across Uzbekistan from 2000 to 2022, with measurements taken every 3 hours. Average wind speed values, wind direction, and energy potential were assessed using the Weibull distribution function. Additionally, maps of annual wind speed and wind power density distributions were developed.

Results: the study revealed that the highest multi-year average wind speeds were recorded in the Republic of Karakalpakstan, Navoi and Bukhara regions, Dekhkanabad district of Kashkadarya region, and Bekabad city in Tashkent region. The areas with the highest wind energy potential were identified as Jaslyk district, the Republic of Karakalpakstan (202.01 W/m²), Navoi city (94.05 W/m²), and Dekhkanabad district (85.33 W/m²).
