The CSP resource classes are defined as follows:
- 1: CF < 0.23
- 2: 0.23 ≤ CF < 0.26
- 3: 0.26 ≤ CF
Site-level CSP supply curve costs are copied from the site-level supply curve costs for utility-scale photovoltaics (UPV). The mapping code is available on the ReEDS input-processing repo at https://github.nrel.gov/ReEDS/ReEDS-2.0_Input_Processing/tree/main/csp.
