The Baltic states are among those countries, where the geothermal potential is underestimated and/or not included in the National Energy and Climate Plans by 2030. Insufficient consideration of this potential hinders the development of geothermal technology and poses a challenge to achieving carbon-neutrality goals. While in the Baltic States more than half of heat demand is covered by district heating (DH) systems, energy generation is based on combined heat and power plants (CHPs) and boilers, consuming both biomass and fossil fuels. Ac cording to the ambitious national energy plans and targets, it is envisaged to increase the share of renewables in heat production. However, the existing energy policies overlook geothermal energy as one of the potential options. Baltic Artesian Basin (BAB) is characterised by a low geothermal gradient, with some anomalies identified at greater depth in central and southwestern Latvia, as well as in the middle and western parts of Lithuania in the Cambrian Deimena, Devonian P¨ arnu-Kemeri and ˇ Sventoji-Upninkai sandy reservoirs aquifers. The main goals of this article are to provide a first comprehensive overview of three Baltic countries – Lithuania, Latvia and Estonia and to map perspective areas, where existing district heating (DH) systems are located within geothermal anomalies. The outcomes of this study provide an open-access information source for consideration and future evaluation of the potential for integration of geothermal energy into the existing DH systems and future DH and cooling systems. Developed maps and compiled data sources are intended to serve as tools for policymakers, investors and other stakeholders. These resources facilitate the viability assessment and explore possible path ways for integrating geothermal energy into DH and cooling networks
