Based on data from international organizations and specialized analytical reviews, the electricity sector's high dependence on natural gas (approximately 76% of generation in 2023) heightens energy security and sustainability risks amid declining gas production and rising electricity demand. An integrated framework for ESG energy transition management (ESG KPIs + scenario-based effects model) is proposed as a methodological solution, focusing on industrial cluster chains (textiles, construction materials, chemicalsmetallurgy, and agro-industrial processing). An assessment of the economic effects of replacing gas-fired power generation with RES is conducted under a scenario in which target benchmarks are achieved by 2030 (scaling RES to 21–27 GW and increasing the share of RES in the electricity supply). The results show that the introduction of renewable energy sources in combination with energy efficiency at the cluster level can provide a sustainable economic effect through the release of gas (alternative cost of fuel), a reduction in electricity costs and losses, an increase in investment attractiveness, and access to “green” financing in the logic of the national green taxonomy. 2026 2026 12 18 10.54216/AJBOR.140103 https://www.americaspg.com/articleinfo/1/show/4247
