The foundation stone for the dam was laid on 5 June 2000 by Prime Minister Atal Bihari Vajpayee. On 14 January 2004, main construction on the dam began. Due to problems associated with habitat and forest loss, the project has been delayed. Attempts to impound the reservoir first failed in December 2013 due to problems with sealing the diversion tunnels. By 18 March 2014, a fourth attempt to seal the tunnels and fill the lake was underway. Repairs were made and another unsuccessful impounding was reached in April 2014 as the diversion tunnels continued to leak. Another period of impounding began on 3 November 2013 and finished on 3 January 2015. A tunnel still leaked though but authorities were confident they would have the power station operational by April. Generator commissioning was originally scheduled for 2009 but was rescheduled to 2015. The first 200 MW Francis turbine-generator was commissioned on 30 March 2015.
