Walchensee Hydroelectric Power Station in Bavaria, Germany, has been in operation since 1924. Water turbines are generally considered a clean power producer, as the turbine causes essentially no change to the water. They use a renewable energy source and are designed to operate for decades.
Hydroelectric projects can be disruptive to surrounding aquatic ecosystems both upstream and downstream of the plant site. Generation of hydroelectric power changes the downstream river environment. Water exiting a turbine usually contains very little suspended sediment, which can lead to scouring of river beds and loss of riverbanks. [48]
Pallivasal Hydroelectric Project is the first hydroelectric project in Kerala, India. The project consists of 2 reservoirs, 2 dams, a diversion dam and a power house and is owned by the Kerala State Electricity Board. The power house of the project has been constructed at Chithirapuram in Pallivasal Gram Panchayat, Munnar, Idukki District.
It is a complex project with four dams including the largest dam on the Koyna River, Maharashtra, hence the name Koyna Hydroelectric Project. The project site is in Satara district. The Koyana Dam situated near Koyananagar village. On river Koyana. The total capacity of the project is 1,960 MW. The project consists of four stages of power ...
The Purulia Pumped Storage Project is a pumped storage hydroelectric power plant, located at Purulia district of West Bengal, India. The Ajodhya Hills offered suitable terrain for construction of upper and lower reservoirs. The scheme can supply a maximum power of 900-megawatt (1,200,000 hp).
Hydropower (from Ancient Greek ὑδρο-, "water"), also known as water power or water energy, is the use of falling or fast-running water to produce electricity or to power machines. This is achieved by converting the gravitational potential or kinetic energy of a water source to produce power. [1] Hydropower is a method of sustainable energy ...
A magnetohydrodynamic generator (MHD generator) is a magnetohydrodynamic converter that transforms thermal energy and kinetic energy directly into electricity.An MHD generator, like a conventional generator, relies on moving a conductor through a magnetic field to generate electric current.
Most current hydroelectric projects use a large hydraulic head to power turbines to generate electricity. The hydraulic head either occurs naturally, such as a waterfall, or is created by constructing a dam in a river valley, creating a reservoir. Using a controlled release of water from the reservoir drives the turbines.
