Strategy for Implementing Hybrid Power Supply Systems in Large-Scale Construction Projects

The organization of power supply at construction sites in Russia, particularly in remote and climatically challenging regions, is characterized by a high dependence on diesel generators for temporary power supply. Fuel delivery is associated with increasing costs, price volatility, and a significant environmental footprint. This article examines the use of hybrid power supply systems (wind turbines, solar photovoltaic panels, and battery storage) as an alternative to conventional diesel-based power supply schemes. Hybrid energy solutions combining diesel generators with renewable energy sources can improve the reliability and economic efficiency of power supply. Rising fuel prices, environmental concerns, and the growing availability of renewable energy technologies are stimulating the adoption of hybrid power supply systems at large construction sites. The methodological framework of this study includes calculations of the Levelized Cost of Electricity (LCOE), Internal Rate of Return (IRR), and Net Present Value (NPV), as well as sensitivity analysis with respect to fuel price fluctuations and wind conditions. The article also presents a comparative analysis of Russian and international practices, demonstrating the increasing role of hybrid power supply systems in the construction sector. The results indicate the high investment attractiveness of hybrid technologies and their potential for scaling up within national programs for economic and construction sector development.
