'''Koradi Thermal Power Station''' (KTPS) is located at Koradi near [[Nagpur]], [[Maharashtra]]. The power plant is one of the four major power plants in [[Vidarbha]] – a power surplus region of India.<ref name="Coal-rich Vidarbha can make Maharashtra power surplus">{{cite web|url=http://www.nerve.in/news:25350046831|title=Coal-rich Vidarbha can make Maharashtra power surplus|access-date=20 April 2015}}</ref> The [[Thermal Power Station|power station]] began operations in 1974 and is one of the nine active power stations operated by [[Maharashtra State Power Generation Company|Maharashtra State Power Generation Company Limited (Prajot)]], a subsidiary of [[Government of Maharashtra]] owned [[Maharashtra State Electricity Board|Maharashtra State Electricity Board (MSEB)]].<ref name="Index of power stations">{{cite web|url=http://www.mahagenco.in/genstats/index_power_stn.shtm|title=Index of power stations|work=Government of Maharashtra|publisher=Maharashtra State Power Generation Company Limited|access-date=2009-01-05|archive-url=https://web.archive.org/web/20091107025121/http://www.mahagenco.in/genstats/index_power_stn.shtm|archive-date=7 November 2009|url-status=dead|df=dmy-all}}</ref> The plant operates 8 units and has a total power generation capacity of 1700 [[Watt|MW]].<ref name="Koradi Thermal Power Station ">{{cite web|url=http://www.mahagenco.in/genstats/koradi.shtm |title=Koradi Thermal Power Station |work=Government of Maharashtra |publisher=Maharashtra State Power Generation Company Limited |access-date=2009-01-05 |url-status=dead |archive-url=https://web.archive.org/web/20091107023059/http://www.mahagenco.in/genstats/koradi.shtm |archive-date=7 November 2009 }}</ref> A proposed 440 kilovolt [[electric power transmission|high power transmission line]] from Koradi to [[Bhusawal]] would join Nagpur with [[Mumbai]].<ref name="Electrical Power System Design">{{cite book|url=https://books.google.com/books?id=8cFV2lnQ_KcC&q=koradi+electricity&pg=PA341|title=Electrical Power System Design|isbn=9780074515754|access-date=20 April 2015|last1=Deshpande|first1=M.

==Power station==
KTPS is located on the northern side of Nagpur and is spread across an area of 30,337 km<sup>2</sup>. Coal for KTPS comes from various nearby collieries of [[Western Coalfields|Western Coalfields Limited (WCL)]] located at [[Silewara]], [[Pipla]], [[Patansavangi]], [[Kamptee]], [[Inder, Maharashtra|Inder]], [[Walni]], [[Gondegaon]] and [[Saoner]]. These are at an average distance of {{convert|10|km|mi}} away. The plant approximately requires 16,000 to 17,000 tonnes of coal per day.<ref name="KORADI POWER STATION : DETAILS AT A GLANCE">{{cite web|url=http://www.mahagenco.in/genstats/data2005-n.pdf|title=Koradi Power Station: Details at a glance|year=2005|work=Government of Maharashtra|publisher=Maharashtra State Electricity Board|access-date=2009-01-05|archive-url=https://web.archive.org/web/20090219051224/http://mahagenco.in/genstats/data2005-n.pdf|archive-date=19 February 2009|url-status=dead}}</ref>

Since its commissioning, KTPS saw expansion in stages. First unit of 115 MW began in 1974. Later, three more units each of 115 MW, were added between 1975 and 1976 while 200 MW unit was added in 1978. The Project Managers for construction of 200/210 MW units were Sri P.S. Khirwadkar followed by Sri C.N.Swamy. Two more units, of 210 MW each, between 1982 and 1983.<ref name="Koradi Thermal Power Station " /> Major developments were undertaken by Ashok R Agrawal who developed the Power Plant. MSEB has finalized further expansion by increasing the capacity of 3 units to 660 MW thereby taking the total capacity of KTPS to 1560 MW. The work is expected to finish by 2014.<ref name="Ongoing projects">{{cite web|url=http://www.mahagenco.in/uploads/projects/Ongoing_%20Project_%20English_may15.pdf|title=Ongoing projects|work=Maharashtra State Electricity Board|publisher=Maharashtra State Power Generation Company Limited|access-date=2009-01-05}}</ref> [[Bharat Heavy Electricals|Bharat Heavy Electricals Limited (BHEL)]] is expected to get equity participation by supplying important equipments in the {{INRConvert|80|b}} expansion plan.<ref name="BHEL may take equity in Koradi power plant">{{cite web|url=http://www.thehindubusinessline.com/todays-paper/tp-corporate/article1670806.ece|title=BHEL may take equity in Koradi power plant|work=The Hindu Business Line|access-date=20 April 2015}}</ref>
