Abstract
The article examines the integration of renewable energy sources into the power supply system of oil and gas ¿elds in Kazakhstan. A hybrid energy system combining solar, wind, and diesel power generation is proposed. The study evaluates the energy, economic, and environmental ef¿ciency of the system. The results demonstrate that renewable energy sources can cover approximately 26% of annual energy demand, reduce diesel fuel consumption by more than 570 thousand liters per year, and decrease CO2 emissions by approximately 1,500 tons annually. The investment ef¿ciency of the project was con¿rmed by a positive Net Present Value (NPV) and an Internal Rate of Return (IRR) exceeding the discount rate. The obtained results con¿rm the feasibility and effectiveness of implementing hybrid energy systems at oil and gas ¿elds in Kazakhstan.
