A conference paper by Beckers and McCabe ( 2018) reported initial progress on the development of GEOPHIRES v2.0. GEOPHIRES v2.0 is distributed as open-source under the permissive MIT license, i.e., others can build upon the framework for commercial and non-commercial purposes.

To address these limitations, as well as to update the cost correlations, improve code readability, and add several new modeling features, a new version (v2.0) has been developed during the period 2017–2018. The capability to model matrix flow reservoirs was limited, and users could not alter the code to implement their own applications or couple to stand-alone models. GEOPHIRES v1.0 was originally applied to assess the technical and economic performance of fracture-based enhanced geothermal systems (EGS) for electricity and direct-use heat applications. The original version of GEOPHIRES (v1.0) was developed by one of the authors during the period 2012–2014 (Beckers et al. The name GEOPHIRES is an acronym that stands for GEOthermal energy for Production of Heat and electricity (“IR”) Economically Simulated, with “IR” representing electric current and resistance and referring to the electricity mode.
Ground-source heat pumps are not considered. Possible end-use configurations are direct-use heat (e.g., for district heating or an industrial process), electricity, and cogeneration or combined heat and power (CHP). Combined with capital and operation and maintenance (O&M) cost correlations, GEOPHIRES applies levelized cost models to estimate the overall required investment and levelized cost of electricity and/or heat (LCOE and LCOH). The simulated output includes the reservoir production temperature and instantaneous and lifetime surface plant heat and/or electricity production. For a given set of input parameters, the tool simulates the subsurface reservoir, wellbore, and surface plant either by using built-in or external user-provided models. GEOPHIRES is a computer code to perform techno-economic simulations of geothermal energy systems.

We include two example simulations and quick-start guide on how to run a simulation.

In this paper, we discuss the GEOPHIRES v2.0 objectives and history, and we present the software architecture as well as built-in models and correlations. Users are encouraged to build upon the tool, e.g., by implementing their own correlations or coupling to other simulators.
Various upgrades have been implemented to develop GEOPHIRES v2.0, including: updating the built-in cost correlations, coupling to the external reservoir simulator TOUGH2, enhancing the built-in wellbore simulator, converting the programming language to Python, and making the code open-source. In addition to electricity generation, direct-use heat applications and combined heat and power or cogeneration can be modeled.
GEOPHIRES combines reservoir, wellbore, and surface plant technical models with cost correlations and levelized cost models to estimate the capital and operation and maintenance costs, instantaneous and lifetime energy production, and overall levelized cost of energy of a geothermal plant. This paper presents a new version (v2.0) of the geothermal techno-economic simulation tool GEOPHIRES.
