Julius Nyerere Hydropower Station (JNHPP; JNHS; RHHP; Rufiji Hydroelectric Power Project; Stiegler's Gorge Dam) is a hydroelectric dam under construction and partially operational across the Rufiji River in eastern Tanzania. Although controversial, the government approved the plans in 2018.
Denawaka Ganga Mini Hydro Power [1] [2] Project is a run of river mini hydro power project located in Ratnapura, Sri Lanka. The install capacity of the project is 7.2 MW and the annual generation is 25GWh. The generated energy is fed into the national electric grid of Sri Lanka.
Kaplan turbine and electrical generator cut-away view. The runner of the small water turbine. A water turbine is a rotary machine that converts kinetic energy and potential energy of water into mechanical work. Water turbines were developed in the 19th century and were widely used for industrial power prior to electrical grids. Now, they are ...
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]
The project was completed in 2012, although partial power generation started in 2011. [19] In April 2010, The EastAfrican, a Kenyan weekly publication, indicated that the opening of the dam would be phased, one unit at a time. [20] On 2 February 2012, Ugandan newspapers reported the commissioning of the first turbine of the power station. [21]
The power station is a hydroelectric power station, using 4 Hitachi turbines of 87 MW installed capacity and the average annual energy generation 900 million units. The station is operated by Tenaga Nasional. Since 1987 Temenggor has been unmanned and is remotely operated via a SCADA system at the Bersia Group Control Centre.
Lower Mettur Hydroelectric Project is a hydropower generation project in the South Indian state of Tamil Nadu. It is a 120MW power generation project constructed across the Kaveri River . The project area is in the downstream of Mettur Dam , hence it derives the name.
In the three dams of this hydroelectric project, the water needed to generate electricity at the Moolamattam power station is pumped through tunnels (penstock pipes) near the pond level. [ 2 ] The water discharged from the power station reaches the Thodupuzha River (a tributary of Muvattupuzha river) which becomes full of water throughout the ...
