Abstract. The peculiarities of the investment sources attracting in the energy saving infrastructure of Ukraine are illuminated. The energy saving infrastructure is proposed to be considered in terms of its elements, such as macro-, meso- and micro-level institutions together with the implemented measures. It is proposed to include world, international and European organizations (such as the Energy Community, World Bank, EBRD, NEFCO, etc.) into the macro-level institutions, which together with meso- and micro-level institutions implement programs and strategies to optimize the irrational use of energy resources. Meso-level institutions include state agencies, ministries, the Cabinet of Ministers, the Verkhovna Rada, the President of Ukraine, large financial institutions, and others. The micro-level institutions are presented by the village, settlement, city councils and their executive bodies; district and regional councils, which represent common interests of territorial communities of villages, settlements and cities; district councils in cities and their executive bodies. In order to improve the forms and methods of attracting sources of investment in energy saving infrastructure, it is necessary to conduct a thorough analysis of the existing measures and programs implemented in the country today. The study of implemented projects, strategies and programs allowed to identify the strengths and weaknesses of each event, as well as areas that need further elaboration. Conclusions are drawn that the investment potential of Ukraine’s energy saving is extremely high and includes measures of various nature, namely: from targeted allocation of funds for the renewal of fixed assets of institutions to educational activities, promotion of measures for the rational use of resources. Also, since the sources of investment are quite widely diversified geographically, it can be argued that the issue of domestic energy conservation is relevant in the global and international arena. Keywords: energy saving, investment, energy saving infrastructure, energy efficiency, Energy Community, World Bank, European Bank for Reconstruction and Development.
