Talcher (old) power station was a 460 MW facility consisting of six units built between 1967 and 1983.[4][5]


The units shut down March 31, 2021. The plant was a major contributor to air pollution and failed to adhere to environmental norms. In 2017, Talcher was one of the ‘critically polluted industrial areas’ in CPCB’s Comprehensive Environmental Pollution Index (CEPI). The city ranked 165 in the list of the world’s most polluted cities, according to the World Air Quality Report, 2020 prepared by IQAir, a Swiss organization.[6][7]

Just Transition questions

The Orissa High Court issued a notice in March 2021 on a PIL seeking its intervention for rehabilitation of contractual employees set to lose their livelihoods due to closure of the power plant. Gadadhar Samal and two other residents of Talcher had filed the PIL in which they stated that the closure of the power plant was going to create serious financial crisis in the locality as thousands of people directly and indirectly depended on it. Chief minister Naveen Patnaik urged Power and New and Renewable Energy Minister R K Singh to direct NTPC to address the concerns related to the closure TTPS and take steps for early execution of the stage-III project.[6]

Proposed 1,320 MW expansion (Stage III)

It was reported in August 2010 that Talcher Thermal Power Station would be expanded by adding two 660 MW units at a cost of Rs 7,000 crore. Tenders for the expansion would be floated by October, 2010, and the project was expected to be completed in five years.[8]

In 2010, NTPC signed a Power Purchase Agreements (PPA) with GRIDCO Limited of Orissa (now Odisha) for sale of power from its proposed Talcher Thermal Expansion.[9]

In 2009, the project received a Terms of Reference from the Ministry of Environment and Forests,[10] and again on October 22, 2014.[11]

In June 2015, NTPC said coal for the expansion would be provided from Mahanadi Coalfields Ltd (MCL) of Coal India.[12]

As of November 2016, NTPC was in the process of planning a new public hearing.[13]

An EIA was submitted in January 2018. It stated the plant would use ultra-supercritical technology, with unit 1 planned for commissioning in 2022 and unit 2 in 2026. Efforts were being made to source the coal from Talcher area of Mahanadi Coal fields.[14]

In April 2018, a top NTPC official said tenders for two 660 MW units at its Talcher power plant were almost ready.[15] Environmental clearance for the units was granted on September 9, 2018.[16] That day, NTPC's board approved an investment of Rs 9,785 crore for the 1,320 MW expansion.[3]

In 2018, NTPC reportedly floated tenders for the expansion project at a cost of R 8,900 crore. However, "no progress could be made as the State government failed to give clearance to the proposal." In February 2020, Odisha government "gave its nod" to the new plant, but NTPC then showed little interest in the expansion project. In 2021, a team from NTPC corporate office came "to review the prospects of the new plant," but nothing was known about its fate. NTPC had reportedly yet to take any steps on setting up the new plant. The unit retirements and lack of interest in the new power plant project allegedly "evoked large-scale resentment not only in Angul but also in Odisha."[17]

In March 2022, NTPC had initiated the tendering process. It would take a "minimum of 48 months to complete construction works."[18]

In May 2022, it was reported that NTPC would award a contract to construct the expansion that month.[19]

In July 2022, it appeared Bharat Heavy Electricals Ltd (BHEL), an Indian electrical company, was selected as the lowest bidder. NTPC appeared to be checking to see if BHEL could advance the project schedule.[20]

In August 2022, the NTPC board approved an investment of ₹11,843.75 crore.[21]

In September 2022, it was confirmed that BHEL had in fact secured the engineering, procurement, and construction (EPC) order.[22]

The November 2022 Broad Status noted the following PPA details, among other things: "PPA signed; Odisha SEB: 50% (660 MW) on 02.08.2022; Tamil Nadu SEB: 35% (460 MW) on 26.09.2022; Unallocated- 15%." The units were expected by 2026 and 2027.[23]

The March 2023 Broad Status Report included the two Talcher Thermal Power Station units in its list of "Under Construction Thermal Power Projects in the country" with 0% physical progress and the expected first trial run dates had not changed (2026 and 2027). [24]

According to the May 2023 Broad Status report, construction of the units had still not begun, but the estimated commissioning dates remained 2026 and 2027.[25]

In August 2023, EPC contractor BHEL had reportedly started delivering boiler parts for the expansion units to the power station.[26]

As per November 2023 Broad Status report, both units have entered construction.[27] In February 2024, Prime Minister Narendra Modi reportedly laid the ceremonious foundation stone for Talcher power station's Stage III.[28][29]

Eviction of Site Inhabitants

In the Central Electricity Authority's 2023 Broad Status Report, the following note was included under "critical issues": "Eviction of unauthorized inhabitants from Munda Basti Area, where Railway siding facility is to be constructed." [24]
