This dataset provides both monthly and weekly constraints (maximum and minimum generation) and power targets for hundreds of hydropower plants across the United States. The data is intended for use in Production Cost Models (PCMs) and Capacity Expansion Models (CEMs). The hydropower data is based on disaggregated annual power data which is part of the EIA-923 dataset. The code to reproduce this data is available here: https://github.com/HydroWIRES-PNNL/B1-data The original disaggregation procedure is detailed here: https://www.nature.com/articles/s41597-022-01748-xhttps://github.com/immm-sfa/turner_voisin_nelson_2022_scientific_datahttps://github.com/pnnl/hydrofixr A paper describing the weekly data is in preperation.
