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.
