Thermal Power Stations – Gas Based

India’s gas-based thermal power sector is a critical component of its energy mix. While many plants areoperational, several are grappling with issues of gas availability and financial distress, leading to reduced output or operational halts. Some projects have been shelved, while others are being repurposed for renewable energy generation, reflecting a broader transition in the nation’s energy policy.

Andhra Pradesh

1. Samarlakota Combined Cycle Power Plant (Reliance Power): The 2,620 MW capacity listed historically for this plant in Samarlakota has been a point of contention. Recent definitive operational data remains scarce. Earlier records indicated a much smaller operational capacity of 220 MW with a low Plant Load Factor (PLF). The plant has been largely non-operational due to gas shortages and financial issues.
2. Lanco Kondapalli Power Plant (Radha Vasavi Assets LLP): Previously owned by Lanco Infratech, this plant in Kondapalli was acquired by Radha Vasavi Assets LLP in June 2023. It has an installed capacity of 1,476.14 MW.

Assam

3. Kathalguri CCPP (NEEPCO): This plant in Kathalguri, operated by the North Eastern Electric Power Corporation, continues to be operational with an installed capacity of 291 MW.
4. Lakwa Thermal Power Station (APGCL): The current operational capacity of this plant in Maibella, Sivasagar, has been significantly derated. Several older units have been decommissioned, bringing its present capacity to 97.2 MW from the earlier 157.2 MW.
5. Namrup Thermal Power Station (APGCL): Located in Dibrugarh, this plant has also seen a substantial reduction in its operational capacity due to the decommissioning of aging units. Its current capacity stands at 41 MW, a marked decrease from the previous 119.5 MW. A 100 MW replacement project is under consideration.

New Delhi

6. Pragati-III Combined Cycle Power Plant (PPCL): This plant in Bawana is operational. Recent regulatory filings in January 2025 confirm its active status, with a capacity of approximately 1,371 MW, close to its commissioned capacity of 1,500 MW.

Goa

7. Goa Gas Power Station (RSPCL): The 50 MW plant in Zuarinagar remains operational but suffers from a very low Plant Load Factor (PLF) due to its reliance on expensive naphtha, making its power uncompetitive.

Gujarat

8. SUGEN Combined Cycle Power Plant (Torrent Power): Located in Akhakhol, Surat, this is a major operational plant. Including the UNOSUGEN expansion, the total capacity stands at 1,530 MW as of May 2025.
9. Pipavav Combined Cycle Power Plant (GSPC): The 700 MW project in Amreli has faced significant delays and its current operational status remains uncertain. While initial development work was undertaken, there is no recent confirmation of its full commissioning.
10. GPEC Combined Cycle Power Plant (Apraava Energy): This 655 MW plant in Paguthan, Bharuch, now owned by Apraava Energy (formerly CLP Group), has been reported as “mothballed” or operating at very low capacity due to commercial unviability.

Haryana

11. Faridabad Thermal Power Plant: The plant listed in Mujedi, Faridabad, under NTPC with a capacity of 431.59 MW was a gas-based plant. However, it is crucial to distinguish it from the Faridabad Thermal Power Station operated by HPGCL, which was a coal-based plant that has been decommissioned and shut down since 2017. The NTPC gas plant is operational but often faces gas shortages.

Jammu & Kashmir

12. Pampore Gas Turbine Station: This 175 MW plant in Pampore, Pulwama, has been non-operational since 2012. The site is now being repurposed for a 10 MW solar power plant, marking a shift from fossil fuels to renewable energy for the region.

Kerala

13. Rajiv Gandhi CCPP (NTPC): This 359.58 MW plant in Kayamkulam is operational but, like many other liquid fuel plants, its generation is dependent on demand and the cost of naphtha.
14. Kochi Combined Cycle Power Station (BSES): The 165 MW plant in Kochi, operated by BSES Kerala Power Limited, is operational. Its Power Purchase Agreement (PPA) has been extended, but it also faces challenges due to the high cost of its fuel (naphtha).

Maharashtra

15. Dabhol Power Station (RGPPL): Now formally known as Ratnagiri Gas and Power Private Limited (RGPPL), this massive 1,967.08 MW plant is operational. However, it has a history of financial troubles and often operates at a fraction of its capacity due to the high cost of imported LNG.
16. Uran Gas Turbine Power Station (MAHAGENCO): This 672 MW plant in Raigad is facing an “operational crisis” as of early 2025. Following a fire in 2022 and ongoing maintenance issues, its power generation is significantly below its installed capacity.

Puducherry

17. Karaikal Gas Turbine Power Station (PPCL): This plant in Karaikal is operational with a slightly updated capacity of 32.5 MW.

Rajasthan

18. Anta Thermal Power Station (NTPC): Located in Baran, this plant is operational with an installed capacity of 419.33 MW.
19. Dholpur Combined Cycle Power Station (RVUNL): The 330 MW plant in Dholpur has been revived and is being operated to meet Rajasthan’s peak power demands, indicating it may not be in continuous operation.
20. Ramgarh Gas Thermal Power Station (RVUNL): Due to the limited availability of domestic gas, only a portion of this plant is currently operational. Out of a total capacity of 270.5 MW, only 110.5 MW is consistently in service.

Tamil Nadu

21. Aban Combined Cycle Power Plant: The current operational status of this 119.8 MW Lanco-owned plant in Karuppur, Thanjavur, is unclear, with no recent information available.
22. Basin Bridge Gas Turbine Power Station (TNEB): The original 120 MW gas turbine station in Chennai is largely considered to be decommissioned or for emergency use only. A proposal for a new, large gas-based plant at the same location was cancelled.

Telangana

23. Gas Engine Power Plant (Astha Power): The operational status of this 35 MW plant in Pashamylaram, Medak, remains unconfirmed in recent official records.

Tripura

24. ONGC Tripura Power Company CCPP (OTPC): This 726.6 MW plant in Palatana, a joint venture with ONGC, is a key operational asset for the region.
25. Agartala GT (NEEPCO): This is an operational combined cycle power plant in Agartala with a capacity of 135 MW.

Uttar Pradesh

26. National Capital TPP (NTPC): The gas-based power plant at Dadri in Gautam Budh Nagar is operational with a capacity of 829.78 MW.
27. Auraiya Thermal Power Station (NTPC): This operational plant in Dibiyapur has a current capacity of 652 MW.

Uttarakhand

28. Gas-based Combined Cycle Power Plant (SEPL): Phase I of this plant in Kashipur, with a capacity of 225 MW, is in commercial operation. However, the project has faced financial challenges, and the status of its proposed second phase is unclear.
