Koradi Thermal Power Station

From Global Energy Monitor

Koradi Thermal Power Station is a 2,400-megawatt (MW) coal-fired power station in Maharashtra, India. An old 210 MW unit is also operating

An additional 1,320 MW expansion is also proposed.


The power station is located at Koradi in Nagpur district of Maharashtra state, India. The satellite photo below shows the three new units of the plant. The existing plant is adjacent to the new units toward the north.

Original Units 1-6

The power station is owned by Maharashtra State Power Generation Company (MSPGCL), a Maharashtra government-owned company. The first four units of 105 MW each were commissioned from 1974 to 1976 and retired in 2010.[1][2] Unit 5 of 200 MW was commissioned in 1978 and retired in March 2017.[3]

Units 6-7 of 210 MW each were commissioned in 1982-1983. They were still operating as of 2017.[2] However, Unit 7 retired in August 2021.[4][5]

New Units 8-10

In 2013, MSPGCL stated on its website that the addition of 1,980MW at the Koradi Thermal Power Station was under construction. The expansion would comprise three 660MW units referred to as Units 8, 9 and 10.[6][7][8][9]

Unit 8 completed a trial run in May 2015.[10] According to the Ministry of Energy, unit 8 commissioned on March 30, 2015.[11]

Unit 9 was commissioned in March 2016.[12]

Unit 10 was commissioned in December 2016.[13]

Proposed Units 11-12

On May 21, 2019, Maharashtra State Power Generation Company Limited (Mahagenco) applied for a 2 x 660 MW expansion at the power station, to be built at the site of the retired units 1-5.[14]

In December 2019, EAC refused to grant clearance for the plant expansion, citing failure to install flue gas desulphuriser (FGD) at the existing units to control pollution.[15]

In June 2020, it was reported the the state cabinet decided to defer the planned expansion, due to revenue shortfall and public opposition. Additionally, the failure of Mahagenco to install pollution controls on the existing Koradi units was making it difficult for the company to secure permits for the expansion.[16]

However, shortly after the June 2020 announcement, and despite the Union environment ministry citing Mahagenco for pollution non-compliances, the expert appraisal committee (EAC) of the ministry granted terms of reference (TOR) for environmental clearance of the proposed expansion.[15]

Coal linkage

In 2015, the proposed new units did not have a long-term coal linkage. In April 2015, Western Coalfields Limited agreed to supply coal to one of the new Koradi units on temporary basis until it gets a permanent linkage.[17]

Air pollution

The ministry of environment, forests and climate change (MOEFCC) made installation of FGD on one 660 MW unit mandatory in the environmental clearance granted to the three 660 MW units in 2010. However, Mahagenco had still not installed a single FGD in 2021.[18]

In April 2017, it was reported that the three new 660 MW units at the Koradi plant exceeded sulphur dioxide pollution limits set by the Ministry of Environment, Forests and Climate Change by over five times. Data supplied by Maharashtra State Power Generation Company to the Maharashtra Pollution Control Board (MPCB) for the units initially claimed the plants met standards, even though they have not been fitted with flue gas desulphurisation units. The discrepancy, which was revealed by a local activist, prompted Modi to demand an investigation. However, as of the time of the reporting the MPCB has taken no enforcement action.[19]

Lawsuit pending

In 2021, Krishi Vigyan Arogya Sanstha through its president Omprakash Jajodia, Kisan Manch through its general secretary Pratap Goswami, and veteran environmentalist Pradyumna Sahasrabhojanee filed a petition highlighting various violations of the environmental clearance that was granted to the power plant in 2010 and amended in 2017, including FGD, fly ash, and water use requirements. Taking serious note of the hazardous public health and environmental impact caused by Koradi, the Pune bench of National Green Tribunal admitted the petition. The petitioners stated various demands, including quashing the terms of reference (ToR) issued to the proposed 2x660 MW expansion and to "issue directives to demolish the work already undertaken."[20][21]


In September 2011, the National Green Tribunal asked the Union Ministry of Environment and Forests (MoEF) to assess the supposed radiation caused by power plants, such as the Koradi power plant. The order was prompted by residents of Kordai town near Nagpu in Maharashtra opposing the expansion of the Koradi power plant. They were worried about the increased radiation from thermal power plants, like Koradi.[22]

The Bengaluru-based start-up, Jhatkaa.org, launched an online petition against the expansion of the Koradi Thermal Power Station (KTPS). The petition is titled,“Scrap the Koradi power unit expansion,” and addressed to the state chief minister, Devendra Fadnavis, and energy minister, Chandrashekhar Bawankule. The petition highlights how there is a water crisis that would be exacerbated by the expansion of KTPS. The organizer wants the petition to reach more public exposure.[23]

On July 18, 2019, protestors voiced opposition against the KTPS expansion, claiming that pollution from KTPS would “sound a death knell for the city.” The protestors included 35 environmental organizations and individuals, such as the Vidarbha Environmental Action Group (VEAG).[24]

A 2021 report by Centre for Sustainable Development, Asar, and Manthan Adhyayan Kendra detailed the devastating impacts of pollution from the Koradi and Khaparkheda coal plants owned.[25][26]
