ASSESSMENT OF WIND TURBINE EFFICIENCY BASED ON LCOE
Kostiantyn POKROVSKIY – Candidate of Technical Sciences, Associate Professor of Electric Power Engineering and Control Systems Department of NU "Lvivska polytechnika" (48/5 ak. Saharova St., Lviv, 79013, Ukraine., e-mail: kpokrov@gmail.com, https://orcid.org/0000-0003-4151-5820).
The paper investigates the techno-economic efficiency of wind power plants using the Levelized Cost of Energy (LCOE) as an integrated performance indicator under real operating and market conditions. The applicability of LCOE as a comparative criterion for modern wind turbines deployed in mountainous regions of Ukraine is substantiated. A hypothetical four-unit wind farm located in the Ukrainian Carpathians is modeled using site-specific wind characteristics derived from a Weibull distribution and open-source datasets. Three state-of-the-art high-capacity wind turbine models are considered: Enercon E-126 7.58 EP8, Vestas V164-8 MW, and Gamesa SG 7.0-170.
Annual energy production, capital expenditures (CAPEX), operational expenditures (OPEX), and projected gross profits are calculated assuming electricity sales on the Ukrainian balancing market. The model incorporates additional costs associated with unscheduled maintenance and post-accident equipment recovery. LCOE values are determined for each wind farm configuration over a ten-year operational horizon. The results indicate closely aligned LCOE values in the range of 0.043–0.044 €/kWh for all turbine types, confirming their high economic competitiveness under the specified conditions.
Sensitivity analysis demonstrates that contingency costs related to equipment restoration exert only a marginal influence on overall efficiency, affecting financial indicators by no more than 5–7%. The obtained results correlate well with empirical data from operating wind farms in comparable environments. The study confirms the technical and economic feasibility of deploying modern high-capacity wind turbines in the Ukrainian Carpathians. The proposed methodological framework can serve as a practical tool for preliminary techno-economic assessment of prospective wind farm sites under real market conditions.

Technology, energy, agriculture transport AIC is a scholarly professional journal with a long-standing history and stable academic tradition, reflecting the evolution of engineering and technical sciences within the agro-industrial sector of Ukraine.
The journal was founded in 1997 under the title Bulletin of Vinnytsia State Agricultural Institute. According to the Resolution of the Presidium of the Higher Attestation Commission of Ukraine dated September 11, 1997, the publication obtained the status of a professional scientific journal, which enabled the publication of the main results of doctoral and candidate dissertations in technical sciences. From its inception, the journal positioned itself as an academic platform for addressing current issues of mechanization, electrification, and technical support of agricultural production. During 2001–2014, the journal was published under the title Proceedings of Vinnytsia National Agrarian University. Series: Technical Sciences (State Registration Certificate of Print Media KV No. 16644-5116 PR dated April 30, 2010). Throughout this period, a systematic approach to the selection and peer review of scientific manuscripts was established, the thematic scope of publications was expanded, and continuity of scientific directions as well as the development of sectoral engineering schools was ensured. Since 2015, the journal has been published under its current title, Technology, energy, agriculture transport AIC (State Registration Certificate No. 21906-11806 R dated March 12, 2016). The change of title reflected the expansion of the journal’s thematic coverage and its orientation toward interdisciplinary research in mechanical engineering, energy systems, electrical engineering, transport technologies, automation, and digital solutions for the agro-industrial complex.
