The Klaipėda Geothermal Demonstration Plant is a geothermal heating plant in Klaipėda, Lithuania, constructed during the late 1990s and early 2000s. It was the first geothermal heating plant in the Baltic Sea region. Its purpose was to reduce carbon dioxide, sulfur dioxide, nitrogen oxide, and particulate emissions in the area, as well as to reduce Lithuania's dependence on foreign energy sources. The plant supplies district heating to the city. Construction was financed by a loan from the World Bank (US$5.9 million) and a grant from the Global Environment Facility (US$6.9 million). The Danish state company Dansk Olie og Naturgas (now DONG Energy) provided technical support, and Enterprise Geoterma (EG) served as the implementing agency.
