 the Ukrainian electricity industry is facing challenges due to depleted production potential and the need for renewable energy sources. Investment is essential to ensure the country's welfare and energy security. This study examined the relationship between key technical and economic parameters and investments in renewable energy sources. It found that one megawatt of additional wind power plant capacity requires an average of 1.51 million euros of investment, while producing one additional kilowatt hour of electricity costs 42 cents. This means that providing an additional 1,000 households with wind-powered electricity would cost 1.345 million euros.
