This dataset contains detailed information on geothermal district heating and cooling systems across the United States, including geothermal direct use-based district heating systems and geothermal heat pump (GHP)-based district heating and cooling systems. The direct use-based district heating information includes technical specifications, costs, energy usage, and funding sources. Data fields include state, site, location, operational years, temperature, flow rate, capacity, energy use, load factor, costs (original, updated, and operational), funding sources, employment impact, and project status. Contributions to these systems are also included, such as federal, state, and local grants, as well as loans from agencies including USDA and USDOE. The GHP-based district heating and cooling portion of the dataset contains locations of current and prospective systems across the United States. The current (operating) installations dataset comprises single large buildings and GHP installations serving more than two buildings. Original data for the operating installations were compiled by DOE from Cross et al. (2011) and multiple public sources, including news clippings, press releases, and developer and college websites. Together, these datasets provide location, technical, cost, and funding information for geothermal district energy systems in the United States.
