'''Ghatghar Dam''' refers to two associated gravity dams built using roller-compacted concrete, the first use in India.<ref>{{cite web|title=Ghatghar Hydroelectric Project may be completed on May 27|url=http://www.thehindubusinessline.in/2006/05/11/stories/2006051100411900.htm|publisher=The Hindu Business Line|accessdate=25 March 2014|date=10 May 2006}}</ref><ref>{{Cite web|url = https://www.constructionworld.in/News/Dam-Good-/87259|title = Dam good - Roller compacted concrete dams|access-date = 11 January 2017}}</ref><ref>{{Cite web|url = https://www.nbmcw.com/report/project-site-reports/285-ghatghar-roller-compacted-concrete-dam-project.html|title = Record Concreting of over 6,50,000 m3 by Patel Engineering Ltd.|access-date = 11 January 2017}}</ref> They are situated in Ghatghar village, in Ahmednagar district Maharashtra, India. Both dams create a lower and upper reservoir for the 250 MW pumped-storage hydroelectric power station. The upper Ghatghar Dam is {{Convert|15|m|ft|abbr=on}} tall and is on the Pravara River, a tributary of the Godavari River.<ref>{{cite web|title=Ghatghar Power House PH01363|url=http://india-wris.nrsc.gov.in/wrpinfo/index.php?title=Upper_Ghatghar_Dam_D05101|accessdate=25 March 2015|archive-date=17 November 2015|archive-url=https://web.archive.org/web/20151117183403/http://india-wris.nrsc.gov.in/wrpinfo/index.php?title=Upper_Ghatghar_Dam_D05101|url-status=dead}}</ref> The lower Ghatghar Dam is {{Convert|86|m|ft|abbr=on}} tall and located on the Shahi Nalla which is a tributary of Ulhas River to the southwest of the upper reservoir in a steep valley. The hydro power project diverts Godavari River basin water outside the basin area to a west flowing river of Western Ghats.

The power station is located between both the upper and lower reservoirs. During peak electricity demand hours, water from the upper reservoir turns two 125 MW reversible Francis turbine-generators. When energy demand is low, such as at night, the turbines reverse direction and pump water from the lower reservoir back to the upper. Construction on the project began in 1995, the dams were placed beginning in 2001 and were complete by 2006. The power station was commissioned in 2008.<ref>{{cite web|title=RCC Dam Database|url=http://rccdams.co.uk/database_results.php|publisher=Malcolm Dustam and Associates|accessdate=24 March 2014|quote=Search for "India"|url-status=dead|archiveurl=https://web.archive.org/web/20151108220724/http://www.rccdams.co.uk/database_results.php|archivedate=8 November 2015}}</ref><ref>{{cite web|title=Ghatagar Dams Project, Maharashtra, India|url=http://www.water-technology.net/projects/ghatagar/|publisher=Water Technology|accessdate=25 March 2014}}</ref>
