This dataset contains monthly and weekly hydropower generation and generation constraints (min, max, daily range) for over 1,400 hydropower plants in the conterminous United States. The dataset includes a historical period (1982-2019) and a future period (2020-2099) with 4 future warming scenarios. For more information please refer to Bracken et al. 2024, godeeep_hydro: Historical and projected power system ready hydropower data for the United States, in prep, or refer to the Github repository https://github.com/GODEEEP/tgw-hydro Data description The dataset contains 10 data files with the naming convention _.csv where scenario can be either "historical", "rcp45cooler", "rcp45hotter", "rcp85cooler", or "rcp85hotter". "monthly" or "weekly" refers to the timestep of the data. datetime - The datetime stamp of the current timestep eia_id - An integer value with the EIA plant code that represents the facility plant - The name of the facility according to the EIA power_predicted_mwh - The total energy gnerated over the period in MWh, aka the energy target n_hours - The number of hours in the period, useful for converting between power and energy p_avg - Average power generation for the period p_max - Maximum allowable power generation for the period p_min - Minimum allowable power generation for the period ador - Average daily operational range for any given day in the period scenario - The name of the scenario, either "historical", "rcp45cooler", "rcp45hotter", "rcp85cooler", or "rcp85hotter" Also included is the metadata file godeeep_hydro_plants.csv which contains metadata for each hydropower plant that is included in the dataset. Each row in this file refers to one hydropower facility. This file has the following columns: eia_id - An integer value with the EIA plant code that represents the facility plant - The name of the facility according to the EIA mode - Either "Storage" or "RoR" indicating if the plant is primarily operated as a storage or ron-of-river facility state - Two letter U.S. state name lat - Latitude of the facility lon - Longitude of the facility nameplate_capacity - The total nameplate capacity of the facility according to the EIA nerc_region - Four letter code for the NERC region of the facility ba - Balacing authority of the facility max_param - Value of the a_{max} parameter used to derive p_max min_param - Value of the a_{min} parameter used to derive p_min ador_param - Value of the a_{ador} parameter used to derive ador huc2 - Two digit hydrologic unit code (HUC) which contains the facility Funding This research was supported by the Grid Operations, Decarbonization, Environmental and Energy Equity Platform (GODEEEP) Investment, under the Laboratory Directed Research and Development (LDRD) Program at Pacific Northwest National Laboratory (PNNL).
