The Randenigala Dam (Sinhala: රන්දෙනිගල වේල්ල) is a large hydroelectric embankment dam at Rantembe, in the Central Province of Sri Lanka.[1] Construction of the dam began in November 1982, and was completed in approximately 4 years. The dam and power station was ceremonially opened by then President J. R. Jayawardene in 1986.[2]

Construction of the dam cost approximately Rs. 4.898 billion (1986), of which 24.6% (Rs. 1.207 billion) was funded by the local government, and the majority of the remainder by Germany.[2]
