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 tunnel continued to leak. Another period of impounding began on 3 November 2014 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.
