 "GETEM" (Geothermal Energy Technology Evaluation Model). Developed at Idaho National Laboratory 2004-2013, this spreadsheet tool is often cited as the standard for geothermal power and cost analysis. The most recent version is from 2016 (Mines, 2016).  "GEOPHIRES" (GEOthermal energy for Production of Heat and electricity 'IR' Economically Simulated). Developed originally as a PhD thesis from 2012 to 2016 by Beckers (2016), GEOPHIRES is now in its second version of development by the National Renewable Energy Laboratory (NREL) (Beckers et al., 2014; 2019; Beckers, 2016).  "NETL" refers to the National Energy Technology Laboratory's series of reports "Cost and Performance Baseline for Fossil Energy Plants: Volume 1 Bituminous Coal and Natural Gas to Electricity" (NETL 2007; 2010; 2012; 2015; 2019b) and the underlying "Cost Estimation Methodology for NETL Assessments of Power Plant Performance" (NETL, 2011; 2019a). These reports provide detailed accounting of natural gas and coal plant components and costs for 14 different power cycle types, both with-and without-CO₂ capture. Originally, these 14 power cycle types were numbered 1 to 14; however, they were renamed in subsequent versions to 'B1A' through 'B31B'. For example, a coal plant using a sub-critical Rankine cycle without CO₂ capture (Case 9 and later 'B11A') is often used for comparison in this manuscript.  "GeoVision" is an extensive, multi-year DOE project to overcome geothermal development barriers. However, we specifically refer to the GeoVision "reservoir maintenance and development" subtask (Lowry et. al., 2017). Lowry et al. (2017) is the primary source for drilling cost data used by genGEO. It is also used by GETEM and GEOPHIRES.  "Kemper Site" is the proposed large-scale CCS complex at the Mississippi Kemper Energy facility described in Esposito et al. (2019). Esposito et al. (2019) provides actual detailed, itemized costs for drilling both monitoring and CO₂ wells and developing a CO₂ site, which are not typically available within most published literature.
