Introduction. In light of the extensive damage inflicted on Ukraine's energy infrastructure by the Russian Federation during ongoing war, it is imperative to explore alternatives for decentralized electricity supply to households and the private sector. This shift toward decentralized power generation aligns with Ukraine's goals for European integration, as outlined in its Energy Strategy until 2050. While specific data on residential distribution remains unavailable for 2024, it's known that around half of Ukraine's population resided in private single-family homes as of 2019. Before the escalation of war, some Ukrainians had already adopted rooftop solar PV installations, resulting in an installed capacity of 1.4 GW by early 2022.
Materials and methods. The study employed a range of methodologies, including systemic analysis, abstract reasoning, economic-statistical analysis, and graph-based techniques. We calculated the levelized cost of electricity (LCOE) to evaluate economic viability of installations.
Results and discussion. The LCOE of electricity produced by autonomous household PVs is notably higher than grid electricity price. Given the current price dynamics, investing in autonomous household PVs is economically unviable. To incentivize decentralized generation and facilitate post-war infrastructure restoration, adjustments such as raising grid electricity price and reducing equipment costs for households willing to invest in PVs are essential. We also examined the feasibility of household participation in “green” auctions and found it to be unfeasible.
Conclusions. The assessment underscores the economic infeasibility of relying solely on autonomous household generating capacities at prevailing grid electricity prices. Similarly, participation in state support programs for renewable energy through auctions is not viable for households. To promote the development of autonomous renewable energy in private households, compensating a portion of equipment costs as a primary state support scheme is suggested. Additionally, measures to lower the cost of loan capital for Ukrainian households are imperative.
