In this paper, we present the results from the development and the simulation of a hydro power model for Sweden and Norway, using SpineOpt software and openly
# Global dataset combining open-source hydropower plant and reservoir data. Analyzing drought and climate change impacts on hydropower potential requires detailed data on both hydropower plant attributes (e.g. plant type and head) and reservoir characteristics (e.g. area, depth and volume). However, existing open-source datasets are poorly integrated: hydropower plant datasets often lack reservoir information, while reservoir datasets commonly miss hydropower plant information. This paper addresses this gap by introducing GloHydroRes, a global dataset that combines existing open-source hydropower plant and reservoir datasets. GloHydroRes includes attributes like plant location, head, plant type as well as reservoir details such as dam and reservoir location, dam height, reservoir depth, area, and volume for 7,775 plants in 128 countries. GloHydroRes covers nearly 79% and 81% of the global installed capacity when compared with installed hydropower data as reported by the EIA(2022) and IRENA (2023), respectively. The open-source GloHydroRes dataset provides crucial data to improve hydropower generation modelling at plant level and can support energy security and planning at continent to global scale.

Most new hydro-electric development was focused on huge “mega-projects.” The majority of these power plants involved large dams which flooded vast areas of land to provide water storage and therefore a constant supply of electricity. HYDROELECTRIC POWER PLANTS Hydroelectric power plants capture the energy released by water falling through a vertical distance and transform this energy into useful electricity. In general, falling water is channeled through a turbine Hydroelectric Power 68 © 2000 PPL Corp. HYDROPOWER which converts the water’s energy into mechanical power. A large volume of water must pass through a low head hydro plant’s turbines in order to produce a useful amount of power. Hydropower: Using the energy of moving water to do work.
Micro-hydro systems generally consist of the following components: • A trash rack, weir, and forebay to pre-vent debris from entering the pipeline and turbine • A pipeline (also called a penstock) to pipe water to the turbine • A powerhouse that contains the turbine and electronics • A water turbine that converts the kinetic energy of the fl owing water into mechanical energy that can be used directly or to drive a generator or other piece of equipment—this is the main component of a micro-hydro system • A tailrace to release the water back into the source it came from • Transmission lines to deliver electrical power where it is needed Th is publication is intended to include as much information as necessary to get you started in the process and to assist you generally at each step along the way of a micro-hydro project.
