reV is an open-source geospatial techno-economic tool that estimates energy technical potential (capacity and generation), system cost, and supply curves for a variety of technologies, including but not limited to, geothermal (GT), pumped storage hydropower (PSH), solar photovoltaics (PV), concentrating solar power (CSP), wind energy, etc. reV allows researchers to include exhaustive spatial representation of the built and natural environment into the generation and cost estimates that it computes. reV is highly dynamic, allowing analysts to assess potential at varying levels of detail — from a single site up to an entire continent at temporal resolutions ranging from five minutes to hourly, spanning a single year or multiple decades. The reV model can provide broad coverage across large spatial extents, including North America, South and Central Asia, the Middle East, South America, and South Africa to inform national and international-scale analyses. Still, reV is equally well-suited for regional infrastructure and deployment planning and analysis.
