Guru Nanak Dev Thermal Plant is situated in Bathinda (Punjab) on Bathinda-Malout Road. The foundation stone of this prestigious Thermal Plant, comprising of four units of 110 MW each was laid on 19th November,1969, the quincentenary year of the birth of the great Guru Nanak Dev Ji from whom it gets its present name. This project was completed in two phases at a total cost of about Rs 115 crore. The first unit was commissioned in September,1974 and the others were subsequently commissioned in September,1975, March,1978 and last one in January,1979. The commissioning of these units not only helped bridge the gap between supply and demand in Punjab but also solved the chronic problem of low voltage prevailing in the Malwa region. Each unit of GNDTP, Bathinda, when operated at full capacity is capable of generating 26.4 lac units of electricity a day. The coal consumption is about 1500 to 1600 MT per unit depending upon the quality of coal. The total daily coal requirement is about 6500 M.T.( about two rakes of 58 wagons each) when all the four units are in operation. The coal supplies are being received from Jharkhand /Madhya Pradesh which are more than 1500 KMs from this Power Station. This power plant has been performing exceeding well over the years. The actual Plant Load Factor during 2004-05 on three unit basis (unit-2 is under R&M) is about 70% which is among the highest achieved in the country for 110 MW units. Conservation of fuel oil in the context of power generation has become a way of working at this power station. As in the previous years, GNDTP has further brought economy in fuel oil consumption during the year 2004-05 in which fuel oil consumption is as low as 1.46 ml/kwh. This consumption level is lowest in the country amongst power stations having similar capacity units. Due to better performance the plant has won a number of National Awards from Govt. of India(Annexure-A). It is a matter of pride that all the four units have successfully completed Silver Jubilee (25 Years) of their operation. At the same time all the units have outlived their designed life. Hence, ’Residual Life Assessment’ study of the units have been got carried out through M/S CPRI, Bangalore. All these units have clocked more than 1,65,000 running hours against designed life of 1,00,000 hours. Accordingly, extensive ‘Renovation & Modernization’ based on Residual Life Assessment (RLA) study of all the four units has been planned to be executed in a phased manner to restore rated capacity of 110 MW in respect of unit-1&2 and enhanced capacity of 120 MW for unit-3&4 , increase efficiency, reduce auxiliary consumption and extend useful life of the plant by another 15-20 years. Work Orders amounting to Rs. 183 crores for major R&M of Boiler furnaces, rotating machinery, H.P. turbine, Instrumentation & Control systems, D.M. Plant, ash handling plant etc. have been placed on M/s NASL, New Delhi for units I & II. The total cost of this project is Rs. 229 crores . Loan for this R&M work has been arranged from M/S PFC, New Delhi. The work also includes updation of Electrostatic Precipitators to bring down SPM (Suspended particulate matter) level below 90 mg/NM3 to reduce pollution in the area. Unit-II has been shut down w.e.f. 9.3.2004 to carry out above mentioned R&M works. The R&M work of this unit is likely to be completed towards the end of August, 2005 to be followed by similar work on Unit-I. In case of unit-III & IV, a project report for R&M costing about Rs.
291 crore has been approved by the Board. The work is to be started during April,2006
and completed by March,2007 i.e. by the end of 10th Five Year Plan. However
to bring down the pollution level till R&M is completed, ‘Ammonia
flue gas conditioning system’ has been installed and SPM level as prescribed
by the ‘Pollution Control Board’ has been achieved on these units.
Generating capacity of unit-III & IV is proposed to be enhanced to 120 MW
from existing 110 MW after replacement of all the three turbine rotors. Main features

Important Telephone Number at GNDTP,Bathinda
R&M WORKS AT GNDTP, Bathinda R&M of GNDTP unit 1&2 has already been completed pending PG Test. R&M works of unit 3&4 is underway to improve performance, enhance capacity and extend operating life of the units. The present status of R&M works of GNDTP units is as under: Unit I&II:- Against approved project Report of Rs 229 Crores, Order was placed on M/S NASL,New Delhi for major R&M works on Turnkey basis at a total of Rs.183 Crores. Unit II: R&M works completed in October, 2005 (Pending attending to some deficiencies by the firm). Average PLF achieved post R&M works is 87% Unit I:- R&M works completed and taken for normal operation in May, 2007(Pending attending to some deficiencies by the firm). Average PLF achieved post R&M during May’07 and june’07 is 95.65%. Unit III & IV:- Order for executing R&M works on Turnkey basis already placed on M/S BHEL at a total cost of Rs. 465.36 Crores. 10% advance payment has been made to M/S BHEL on 22/12/2006 and design and drawing work is in progress. As per Schedule, work is to be completed in a phased manner upto July 2009. Apart from enhancing the operating life and performance level of the units, it is also planned to uprate the capacity from 110 MW to 120 MW each resulting in total capacity addition of 20 MW. |
