The '''Koldam Hydropower Station''' commonly known as '''Koldam''', is an [[embankment dam]] on the [[Sutlej|Satluj River]] upstream of the [[Dehar Power House]]. It is 18 km from Bilaspur off the Chandigarh-Manali Highway (NH-21) near Barmana, [[Himachal Pradesh]], India. The main purpose of the dam is [[hydroelectric]] power generation and it will support an 800 MW power station. The dam was constructed by National Thermal Power Corporation (NTPC).<ref>{{Cite news|title = BHEL starts NTPC's 800-MW Koldam hydro power plant - The Economic Times|url = http://economictimes.indiatimes.com/industry/energy/power/bhel-starts-ntpcs-800-mw-koldam-hydro-power-plant/articleshow/47674211.cms|website = The Economic Times|access-date = 2016-01-09}}</ref>

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.<ref name=main/> 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.<ref>{{cite news|title=Impounding of water in NTPC's Koldam hydel project begins|url=http://powerbusinessview.com/index.php/component/k2/item/1024-impounding-of-water-in-ntpc-s-koldam-hydel-project-begins|access-date=1 April 2014|newspaper=Power Business View|date=18 March 2014}}</ref> Repairs were made and another unsuccessful impounding was reached in April 2014 as the diversion tunnel continued to leak.<ref>{{cite news | url=http://timesofindia.indiatimes.com/india/NTPC-conducts-reservoir-impounding-for-Kol-dam-project/articleshow/33475119.cms | title=NTPC conducts reservoir impounding for Kol dam project | date=9 April 2014 | newspaper=The Times of India | access-date=13 May 2014}}</ref> Another period of impounding began on 3 November 2014 and finished on 3 January 2015.
