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.
Micro hydro is a type of hydroelectric power that typically produces from 5 kW to 100 kW of electricity using the natural flow of water. Installations below 5 kW are called pico hydro . [ 1 ] These installations can provide power to an isolated home or small community, or are sometimes connected to electric power networks, particularly where ...
Thermal power stations in Sri Lanka now roughly match the installed hydroelectric generation capacity, with a share of nearly 49% of the available capacity in December 2013 and 40% of power generated in 2013. [9] Thermal power stations in Sri Lanka runs on diesel, other fuel oils, naptha or coal. [9]
Sketch of the Power Plant. The developer of the project is Vallibel Power Erathna PLC [1] and the project is developed on a build, own and operate basis. The intention of the company is to generate 40 GWh [1] of green energy annually and to export it to the national electricity grid of the Ceylon Electricity Board which is the only authorised Institute for electricity transmission in Sri Lanka ...
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.
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.
The 220kV transmission line of the Upper Kotmale Hydro-power Project connects the power station located at Niyamgamdora, Kotmale, to the national grid via Kotmale switch yard located in Atabage, Gampola. The line consists of 45 towers and has a length of 15.5 km. The double circuit transmission line has a capacity of 220 MW per circuit.
The following page lists most dams in Sri Lanka. Most of these dams are governed by the Mahaweli Authority, while the Ceylon Electricity Board operates dams used for hydroelectric power generation. Hydroelectric dams, including small hydros, account for nearly half of the installed power capacity of Sri Lanka.
