The '''Purulia Pumped Storage Project''' is a [[Pumped storage hydroelectricity|pumped storage]] [[Hydroelectricity|hydroelectric]] power plant, located at [[Purulia district]] of [[West Bengal]], India. The [[Ajodhya Hills]] offered suitable terrain for construction of upper and lower reservoirs. The scheme can supply a maximum power of {{convert|900|MW|adj=on}}.

== Construction ==
The project is constructed on Kistobazar [[nullah]] which is a tributary of Sobha nullah in [[Ajodhya Hills]]. The project was planned to be commissioned in 2002-03, but litigations during tender stage and difficulties in getting clearance for forested land caused delays to the project.<ref>{{Cite web |title=Purulia Pumpde Storage Scheme |url=http://www.infraline.com/power/State/WB/PuruliaHEP.aspx?AspxAutoDetectCookieSupport=1 |archive-url=https://web.archive.org/web/20220328045619/http://www.infraline.com/power/State/WB/PuruliaHEP.aspx?AspxAutoDetectCookieSupport=1 |archive-date=2022-03-28 |access-date=2022-03-28 |website=www.infraline.com}}</ref> Japan International Cooperation Agency (JICA) provided {{INRConvert|2272|c|year=2016}} of loan assistant for the project.<ref name=":2">{{Cite web |date=2022-03-23 |title=Welcome to WBSEDCL |url=https://www.wbsedcl.in/irj/go/km/docs/internet/new_website/PPSP.html |access-date=2022-03-23 |archive-url=https://web.archive.org/web/20220323082820/https://www.wbsedcl.in/irj/go/km/docs/internet/new_website/PPSP.html |archive-date=2022-03-23 }}</ref>

The local villagers protested against the project, as the villagers alleged massive loss of vegetation in the area and hundreds of villagers allegedly lost their livelihoods.<ref>{{Cite news |last=Singh |first=Shiv Sahay |date=2020-02-28 |title=Tribals to heighten protest over Ajodhya Hills hydel project |language=en-IN |work=The Hindu |url=https://www.thehindu.com/news/national/other-states/tribals-to-heighten-protest-over-ajodhya-hills-hydel-project/article30935944.ece |access-date=2022-03-28 |archive-url=https://web.archive.org/web/20200228171631/https://www.thehindu.com/news/national/other-states/tribals-to-heighten-protest-over-ajodhya-hills-hydel-project/article30935944.ece |archive-date=2020-02-28 |issn=0971-751X}}</ref>

== Purpose ==
The objective of project is to meet load demand by producing power through the turbines at the [[Peaking power plant|peak load]] time and utilize surplus power available of the system during off peak time by pumping the water to upper reservoir, thus achieving the flatter load demand curve and maintaining the frequency.<ref>{{Cite news |last=Reporter |first=B.

It is operated not only to help meet the peak loads but also as a short term operating reserve (STOR), providing a fast response to short-term rapid changes in power demand, both hike and drop, or sudden loss of power generating stations. On 5 April, 2020 when people switched off their lights at 9 PM by request of [[Prime Minister of India|Prime Minister]] [[Narendra Modi]] for solidarity in fight against [[COVID-19 pandemic]], the West Bengal grid load was expected to dropped by 1 [[Watt#Gigawatt|GW]].<ref name=":3">{{Cite news |last=Sengupta |first=Debjoy |title=Purulia Pump Storage Plant to save West Bengal from grid crash on Sunday 9 PM as 1 GW demand vanishes |work=The Economic Times |url=https://economictimes.indiatimes.com/industry/energy/power/purulia-pump-storage-plant-to-save-west-bengal-from-grid-crash-on-sunday-9-pm-as-1-gw-demand-vanishes/articleshow/74981810.cms |access-date=2022-03-23 |archive-url=https://web.archive.org/web/20220323131553/https://economictimes.indiatimes.com/industry/energy/power/purulia-pump-storage-plant-to-save-west-bengal-from-grid-crash-on-sunday-9-pm-as-1-gw-demand-vanishes/articleshow/74981810.cms |archive-date=2022-03-23}}</ref> While the [[National Grid (India)|national grid]] load was estimated to drop by 12 - 14 GW, far from the estimate the national grid power demand was dropped 31 GW in a span of 25 minutes.
