Vesivoimakohteita, or hydroelectric power plants, are facilities that convert the energy from falling or flowing water into electricity. They are a significant source of renewable energy, contributing to the global electricity supply. Hydroelectric power plants operate by utilizing the potential energy of water stored in reservoirs or the kinetic energy of flowing water in rivers and streams. The primary components of a hydroelectric power plant include a dam or diversion structure, a water intake, a turbine, a generator, and a transformer.

There are two main types of hydroelectric power plants: impoundment and run-of-the-river. Impoundment plants store water in reservoirs behind dams, releasing it to drive turbines when electricity is needed. Run-of-the-river plants, on the other hand, do not store water and generate power from the natural flow of rivers. Both types can be further categorized based on the type of turbine used, such as Pelton, Francis, or Kaplan turbines, each suited to different water flow conditions.

Hydroelectric power plants offer several advantages, including high energy output, low greenhouse gas emissions, and the ability to provide reliable and dispatchable power. However, they also have environmental and social impacts, such as habitat disruption, water quality changes, and potential displacement of local communities. Proper planning, environmental management, and community engagement are essential to mitigate these impacts and ensure the sustainable development of hydroelectric projects.
