The co-generation option considers bottoming +cycle, topping cycle, and parallel cycle. + +GEOPHIRES has 4 economic models to calculate the levelized cost of heat or +electricity: (1) fixed charge rate (FCR) model; +(2) standard discounting levelized cost model; +(3) BICYCLE model; +(4) CLGS. + +The capital and O&M costs for the different geothermal system components (exploration, +well drilling, surface plant, etc.) are either provided by the user or calculated with built-in +correlations. Parameters ---------- Available parameters are documented in the `Parameters Reference `__. +Note that many parameters are interrelated and/or conditionally dependent on one another; +reviewing the GEOPHIRES example(s) relevant to your use case in the following section +is strongly recommended to gain a working understanding of how to construct valid sets of input parameters. + Examples -------- -GEOPHIRES includes a variety of examples demonstrating its features and case studies for different types of geothermal systems. +GEOPHIRES includes a variety of examples input files demonstrating its features for different types of geothermal systems +and case studies of real-world geothermal projects. Starting with an existing GEOPHIRES example that is similar to your intended use/application can be an easier approach to using GEOPHIRES than constructing your own inputs from scratch.
