A pico hydro system made by the Sustainable Vision project from Baylor University [1]. Pico hydro is a term used for hydroelectric power generation of under 5 kW. These generators have proven to be useful in small, remote communities that require only a small amount of electricity – for example, to power one or two fluorescent light bulbs and a TV or radio in 50 or so homes.

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 amount of hydroelectric power generated is strongly affected by changes in precipitation and surface runoff. [4] Hydroelectric stations exist in at least 34 US states. The largest concentration of hydroelectric generation in the US is in the Columbia River basin, which in 2012 was the source of 44% of the nation's hydroelectricity. [5]
The water wall turbine is a water turbine designed to utilize hydrostatic pressure differences for low head hydropower generation. It supports bidirectional inflow operation using radial blades that rotate around a horizontal axis. The water wall turbine is suitable for energy extraction from tidal and freshwater currents.
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.
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 ...
The project, when complete, will increase the power generation capacity of the Mangla Dam to 1,310 MW from the existing 1,000 MW capacity. WAPDA successfully commissioned two refurbished generating units of the Mangla Hydel Power Station on 23 May 2022, increasing their capacity from 200 MW to 270 MW.
The Parbati-II hydroelectric project is being developed in Pulga and Suind villages, in the Kullu district of Himachal Pradesh. The project consists of construction of a 83.7m-high concrete gravity dam in the Pulga village in the downstream of Parbati River and Tosh Nallah, and surface powerhouse with four Pelton Turbine Generator units with ...
