On 23rd October 2017,  Bharat Heavy Electricals Limited (BHEL) received Letter of Intent (LOI) for execution of Yadadri *Super Critical Thermal Power Project (TPP) from  Telangana State Power Generation Corporation Limited (TSGENCO). The order value of this 4,000 MW TPP is approx. Rs. 20,400 Cr. This is the single largest order received by BHEL and highest value order in the history of power sector of India.

BHEL’s Association with Telangana

In the state, BHEL has been working hand in hand with TSGENCO. The equipment used in 86 % of the installed capacity of coal based power plants in the state have been supplied by BHEL. On 4th October 2014, TSGENCO had signed an MoU with BHEL for establishing thermal projects of the combined generating capacity of 6,000 MW in the state.

This target included -Yadarai power project of 4,000 MW, Bhadradri power project of 1,080 MW and Kothagudem of 800 MW. The later two projects are in advance stage of execution.

Yadadri Supercritical Thermal Power Project


Site for Yadadri TPP is located in Damaracherla in Nalgonda district of Telangana. The plant shall have 5 units of 800 MW Super Critical sets. The total area alotted for the project is 2,800 acres near Veerlapalem. The Government of Telegana had announced it after Bhadradri Thermal Power Plant in the state.

BHEL has bagged this order for design, supply, erection and commissioning of project / on Engineering, Procurement and Construction (EPC) basis. The project shall be executed phase-wise and it is expected to be completed by October 2021. This project shall help BHEL expand largely its executable order book.

Environmental Concerns

Despite the foundation ceremony, Yadadri project was held-up for approximately two and a half years. The major hurdles were non-clearance by National Green Tribunal (NGT) due to environmental concerns and delay caused by the appraisal committee of the Union Environment Ministry over technical factors.

In June 2017, the project got the environmental clearance from the Ministry of Environment, Forest and Climate Change (MoEF & CC) and is now looking forward for water allocation from Krishna river.

BHEL’s strategy for this project is to work on fast track basis in line with other held-up project, namely 4*270 Bhadradri Thermal Power Plant which was also held-up due to Environmental Clearances.

Telangala’s Thermal Power Generation

Thermal energy is the biggest source of energy in the state. The total installed capacity of Thermal power plants in Telangana is 6,682.5 MW and further 11,580 MW is under construction with biggest chunk of contribution by Yadadri TPP.

About BHEL: India’s largest power generation equipment manufacturer was established in 1964. BHEL holds the highest  number of Super Critical sets ordered in the country for thermal power plants accounting to 48 Super Critical Steam Generators (SG) and 41 Super Critical Steam Turbine Generators (STG). Beyond this 15 SG’s and 13 STG’s have achieved capacity addition.

* Super Critical Thermal Power Projects are those in which the running water works as a Super Critical fluid, which means it is neither liquid nor gas. This takes place when water reaches its critical point under very high pressures and temperatures, specifically at 22 MPa and 374°C. [Energy Education, University of Calgary]
