Koradi Thermal Power Station (KTPS) is located at Koradi nearNagpur,Maharashtra. The power plant is one of the four major power plants inVidarbha – a power surplus region of India.[3] Thepower station began operations in 1974 and is one of the nine active power stations operated byMaharashtra State Power Generation Company Limited (Prajot), a subsidiary ofGovernment of Maharashtra ownedMaharashtra State Electricity Board (MSEB).[4] The plant operates 4 units and has a total power generation capacity of 2190MW.[1] A proposed 440 kilovolthigh power transmission line from Koradi toBhusawal would join Nagpur withMumbai.[5] KTPS campus also contains training institute of MahaGenco for middle and senior level engineers, technicians and other staff.[6]
KTPS is located on the northern side of Nagpur and is spread across an area of 3.337 km2. Coal for KTPS comes from various nearby collieries ofWestern Coalfields Limited (WCL) located atSilewara,Pipla,Patansavangi,Kamptee,Inder,Walni,Gondegaon andSaoner. These are at an average distance of 10 kilometres (6.2 mi) away. The plant approximately requires 16,000 to 17,000 tonnes of coal per day.[2]
The water for KTPS comes from water reservoir of nearbyTotaladoh hydroelectric power station.[7] Also,Nagpur Municipal Corporation (NMC) provides treated water from its sewage treatment plant.[8] According to MSEB, the average unit cost of power generation at KTPS is 320paise/kWh at 70 percentload factor while it is 13.52 paise/kWh at 25 percent load factor. The average cost for transmitting this power to Mumbai is 1.26 paise/kWh.[9]
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.[1] 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,was added between 1982 and 1983.[1] Major developments were undertaken by Ashok R Agrawal who developed the Power Plant. MSPGCL has further Added 3 units of 660 MW. 660 MW units were inaugurated by Prime minister of India in April 2017.where as Unit no 7 has been discommisson in 2021. As of Jan 2023, the total capacity of KTPS is of generating 2190 MW.[10]L&T is expected to get equity participation by supplying important equipments in the₹80 billion (US$950 million) expansion plan.[11]
In order to reduce air pollution the plant's units are equipped withelectrostatic precipitators.[12]

TheCentral Power Research Institute (CPRI) ofGovernment of India, which serves as regulating body for testing of instruments and uploading of licenses in India, is going to set up aThermal Research Centre (TRC) at Koradi. However, the KTPS expansion plans have created a problems in land acquisition for TRC.[14]
On 27 February 2005, a major fire broke out at KTPS and had to be shut down causingblackouts in most districts ofMarathawada.[15] In May 2007, the power plant was shut down due a strike by workers.[16]
Mahagenco has sought permission from Maharashtra Electricity Regulatory Commission (MERC) to close down unit 5 and 6 of Koradi (200 MW and 210 MW).Genco wants to shut 1,040MW generationAshish Roy | TNN | 4 July 2014
