This dataset includes files for a techno-economic analysis conducted using the GEOPHIRES simulator to examine the feasibility of expanding a larger district heating site in a remote location: Pilgrim Hot Springs, Alaska. Files included here are GEOPHIRES inputs and outputs for five different scenarios with varying demand, cycle, and system design characteristics to analyze. Also included is the link to the GEOPHIRES GitHub, as well as a link to the dataset that contains the energy modelling used to determine the heating demand for the district. For a list of the differences between scenarios, see the included "Input Overview.txt" file. Fields included in the input files are: subsurface technical parameters, surface technical parameters, financial parameters, capital and O&M parameters, as well as simulation parameters. The output files are case reports that summarize all equipment, reservoir characteristics, costs, and heating profiles.

Pilgrim Hot Springs is in the Seward Peninsula, western Alaska, approximately 60 road miles north of Nome. Pilgrim Hot Springs has reported surface temperatures ranging from 145 degrees F to 160 degrees F (63 degrees C-71 degrees C) (Miller and others, 1973; Motyka and others, 1983). Due to the proximity to a large community, Pilgrim Hot Springs is considered a potential resource for providing power or direct-use heat. As a pilot study to inform ongoing investigation of the subsurface geology of Pilgrim Hot Springs, DGGS staff collected 29 controlled source and natural source audio magnetotelluric (CSAMT) readings to develop resistivity models of the study area. This data release provides Stratogem format raw data and resistivity models and depth slice grids in ASCII text and GeoTIFF format. The data, as well as additional metadata, are available from the DGGS website: http://doi.org/10.14509/30472.

This submission contains the source code of the Hydrothermal Finite Element Simulator used for the Treasure Island and UC Berkeley campus geothermal simulation. It contains a report that summarizes the development and validation of this Hydrothermal Finite Element Simulator, with a case study on Treasure Island site. It also contains a report that investigates the feasibility of upgrading the existing campus energy delivery system at UC Berkeley to a fifth-generation district heating and cooling system that includes geothermal heat/cold storage.

This data release documents eight 30-year SUTRA simulations summarized in Pepin and others (2025) and provides output from one short (1-year) simulation to provide verification that the model code runs properly. The most recent, but not-yet published, version of SUTRA (version 4.0) was used to evaluate reservoir thermal energy storage performance by simulating radially symmetric groundwater and heat transport for layered systems in the following eight metropolitan area cities: Albuquerque, New Mexico; Charleston, South Carolina; Chicago and Decatur, Illinois; Lansing, Michigan; Memphis, Tennessee; Phoenix, Arizona; and Portland, Oregon. This U.S. Geological Survey (USGS) data release contains the input and output files for those simulations described in Pepin and others (2025). The SUTRA (version 4.0) executable and Python script needed to run the simulations are currently only made available to USGS users (see child item) because the required supporting documentation for public release has not yet been published. Users are encouraged to review Pepin and others (2025) to understand the purpose and limitations of this model.

This dataset contains materials from the Coalition for Community-Supported Affordable Geothermal Energy Systems (C2SAGES) project, which evaluated the techno-economic feasibility of a community geothermal system for a residential development in Hinesburg, VT. The dataset includes detailed soil conductivity test reports, energy models, borehole design reports, hourly energy loads for heating, cooling, and hot water, and design layouts. EnergyPlus was used to model building energy loads, and Modelica software was applied for geothermal loop sizing based on these loads and soil conductivity results. Python scripts for network design further refined the models. Key files include PDF reports on borehole design (with projections for 1-year, 15-year, and 30-year systems), soil conductivity test results, EnergyPlus modeling outputs, and 2D/3D design drawings in PDF, DWG, and DXF formats. Python notebooks for network design and OnePipe model files are also provided, with Modelica required for viewing certain files. Outputs and modeling data are in various formats including CSV, JPG, HTML, and IDF, with units and data clearly labeled to support understanding of system design and performance for the proposed geothermal solution.
