The Broadlands Dam (also known as the Broadlands Hydropower Project by the developers) is a run-of-the-river hydroelectric complex currently under construction in Kitulgala, Sri Lanka. The project is expected to be completed in 2020, and will consist of two dams, and a power station downstream.[1] [2]
With an estimated annual generation capacity of, the facility will be the country's last major hydroelectric project, due to the exhaustion of island-wide hydropower potential. Construction of the project was ceremonially inaugurated by the at the auspicious time of 11:01 on .[3] [4]
Approximately project funding was met via credit arrangements made with the Chinese government, with the rest borne via a loan from the local Hatton National Bank.[5] [6] [7] The construction contract of the project was granted to the China National Electric Equipment Corporation (CNEEC).[8]
The primary gravity dam measuring 240NaN0 in height and 1140NaN0 in length is being constructed across the Maskeliya Oya at Kitulgala, and will supply water to the power station via a 3404.71NaN1 penstock measuring 5.41NaN1 in diameter.[9]
A secondary gravity weir, measuring 190NaN0 and 480NaN0 in height and length, is also to be built in the vicinity, over the nearby Kehelgamu Oya, to provide additional hydroelectric capacity. The weir, to be called the Kehelgamu Weir, will create a catchment area of 1760NaN0, and will provide additional head to the penstock of the main dam via a 8110NaN0 tunnel.
The penstock from the main dam will feed a power station consisting of two turbines, each of and a rated discharge of .
