ABSTRACT: The article addresses the pressing issue of limited access to centralized energy supply for peasant and farm enterprises in the West Kazakhstan region, which significantly hinders the efficient operation of agricultural production. This problem is especially critical for the development of livestock farming, irrigation, and water supply systems in remote and hard-to-reach rural areas. The absence of reliable and continuous electricity sources negatively affects technological processes, increases operational costs, and reduces the overall sustainability and productivity of the agricultural sector. In this context, particular attention is given to the organization of autonomous energy supply systems based on renewable energy sources, primarily wind energy, to support groundwater extraction from wells used for domestic, drinking, and agricultural purposes.An analysis of the wind potential of the Republic of Kazakhstan demonstrates favorable conditions for the development of small-scale wind energy as a cost-effective and environmentally sustainable solution for decentralized power supply. It is shown that low-capacity wind energy installations designed to operate at low wind speeds (3–5 m/s) can efficiently drive pumping systems, ensuring stable groundwater lifting under rural conditions. The study substantiates the selection of a low-speed horizontal-axis multi-blade wind turbine as the most suitable configuration for such applications.A comparative analysis of the energy performance of different wind turbine types is conducted, focusing on the relationship between the power coefficient and the tip speed ratio. Based on the obtained results, the optimal geometric parameters of the rotor blades are determined, contributing to improved energy efficiency and operational reliability. The findings of the study can be applied in the design and implementation of autonomous wind-powered water supply systems for agricultural enterprises and the agro-industrial sector.
