GURU NANAK DEV THERMAL PLANT, BATHINDA
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.
The historic town of Bathinda was selected for this first and prestigious thermal power project of the state due to its good railway connections for fast transportation of coal, availability of canal water and proximity of load center. 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. It is matter of pride that this plant is working successfully since its commissioning.
This plant has won many National Awards like Meritorious Productivity Awards from Govt. of India. GNDTP, Bathinda has also been accredited with ISO: 9001:2008.
Unit-1or 2 of GNDTP, Bathinda, when operated at full capacity is capable to generate 26.4 lac units of electricity in a day and unit-3 or 4 when operated at full capacity is capable to generate 28.80 lac units in a day. The coal consumption is about 1800 to 1900 MT per unit depending upon the quality of coal. The total daily coal requirement is about 7400 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 which is more than 1500 KMs from this Power Station. Fly ash generated is being used by M/s Ambuja Cement factory and other different industries.
As these units had completed more than their designed life span of 25 years, the Renovation & Modernization has been done in the phased manner with the following objectives:
- To restore original rated capacity of the units. (Uprating of capacity from 110MW to 120 MW for units 3 & 4)
- To improve plant availability/load factor.
- To extend the life of the units by 15 to 20 years.
- To enhance operational efficiency and safety
- To remove ash pollution and to meet up environmental standards of Pollution Control Board
- Energy Conservation
“R&M of Units-1,2 was completed during the period Mar,2004 to May,2007 and these units are running at nearly full capacity. After R&M, unit-3 has been considered w.e.f 07.12.2012 (being its COD).Its capacity has been up-rate from 110 MW to 120 MW. R&M of unit-4 has been completed and its capacity has been up-rate from 110 MW to 120 MW w.e.f 27.09.2014 (being its COD). Now the Station capacity of GNDTP, Bathinda is 460 MW w.e.f 27.09.2014.
