Hydropower schemes can broadly be classified into four main types: run-of-river (ROR), storage (reservoir-based), pumped storage hydro (PSH) and in-stream (hydrokinetic) technologies. 21.3.1 Run-of-River. Hydropower plants mainly generate electricity from the available flow in a river. Some short-term storage (a pond) may be included, allowing
To date, Pumped Hydro Storage is the most mature and widely adopted storage technology while CAES and flow batteries are commercially mature technologies but with a limited spread. On the contrary, GES, LAES, Hydrogen Storage and PTES can be considered in-developing large-scale energy storage technologies. 2.1.

South Africa requires 40,000MW power by 2025. Ingula is one of the projects being constructed to meet the future demand. The scheme is being built on a 9,000ha site by state-owned Eskom at a cost of R8.9bn. The work on the facility began in November 2007 and is expected to be complete by 2012. It will be fully operational by 2013.

Hydropower in Australia. Hydroelectricity has been providing around 5-7 per cent of Australia''s total electricity supply for decades. There are over 120 operating hydroelectric power stations in Australia, large and small, mostly located in south eastern Australia. The most well known of these is the Snowy Mountains Hydro-Electric Scheme.

Hydropower is a controllable (or dispatchable) renewable energy source. This is in part due to control over the source through its storage capabilities, and the greater predictability of its generation in comparison to wind and solar power. Hydropower is, however, variable over longer time scales, as it depends on precipitation and water run-off.
A small-scale hydropower station is usually a run-of-river plant that uses a fixed speed drive with mechanical regulation of the turbine water flow rate for controlling the active power generation.This design enables to reach high efficiency over a wide range of water flows but using a complex operating mechanism, which is in consequence
