[9] [needs update] Hydroelectric power generation has been constantly under development since the introduction of the national grid itself, but its market share is declining because suitable new sites are scarce. Currently, ten large hydroelectric power stations are in operation, with the single largest hydroelectric source being the Victoria Dam.
The installed electrical capacity and production of Sri Lanka by sources, from 2000 to 2018. Sri Lanka's electricity demand is currently met by nine thermal power stations, fifteen large hydroelectric power stations, and fifteen wind farms, with a smaller share from small hydro facilities and other renewables such as solar.
The Moragahakanda Dam (Sinhala: මොරගහකන්ද ව්යාපෘතිය), officially Kulasinghe Reservoir, [1] is a large gravity dam, and the main component of the larger and more complex Moragahakanda — Kalu Ganga Project, across the Amban River at Elahera, in the Matale District of Sri Lanka.
Irrigation dams with a length and height of more than 100 m (330 ft) and 10 m (33 ft) are listed, including all the state-run hydroelectric power stations. Privately owned "small-hydro" facilities (which are limited to a maximum nameplate capacity of 10 MW), are not included in this list. Nearly all hydroelectric dams are also used for ...
The Samanala Dam (Sinhala: සමනලවැව වේල්ල) is a dam primarily used for hydroelectric power generation in Sri Lanka.Commissioned in 1992, the Samanalawewa Project (Samanala Reservoir Project) is the third-largest hydroelectric scheme in the country, producing 405 GWh of energy annually.
The power station, which is also called as the Samanala Hydroelectric Power Station, consists of two generation units rated at 37.50 MW each, both of which were commissioned in April 1969. [1] [2] [3] Upstream view of the Laxapana Dam and Reservoir.
In addition to downstream irrigation, water from the reservoir is used to power the Inginiyagala Power Station, a hydroelectric power station located immediately downstream of the dam. The power station consists of four units of (2.475MWx2 & 3.15MWx2) 11.25 MW , commissioned in 1952 unit 1,2 & 1962 unit 3,4.
Each spillway gate measures 9.3 m (31 ft) high and 12 m (39 ft) wide, and uses the same automated technology as the Victoria Dam. [3] The dam creates the Kukule Ganga Reservoir, which has a capacity and catchment area of 1,630,000 m 3 (58,000,000 cu ft) and 312 km 2 (120 sq mi) respectively. After passing through the dam and sand traps, water ...
