Indian state-owned power plant equipment manufacturer Bharat Heavy Electricals Ltd (BHEL) has announced the completion of renovation and modernization work at the Barauni coal-fired power plant in Bihar.
The 320 MW plant (pictured) came online in 1985, and BHEL says its working life has now been extended by an additional 15-20 years.
The project closely followed similar renovation of several other plants, the company said, including two 110 MW units at the Kanti coal-fired plant in Muzaffarpur, Bihar. Renovation was also performed on units 3 and 4 of the 440 MW Guru Nanak Dev plant in Bahtinda, Punjab, which came online in 1979, while unit 7 of a plant owned by Uttar Pradesh Rajya Vidyut Utpadan Nigam Ltd (UPRVUNL) was upgraded from 110 MW to 120 MW.
According to BHEL, of the 218 units between 110 MW and 210 MW that it has supplied to utilities, 142 have outlived their design lifetimes. Of these, 38 have already been renovated or have renovation work in progress.
New national emissions limits for SOx and NOx have also led to the need for upgrades to India’s coal-fired plants, BHEL said.
