Power plant contractor saves cost while exposing UPRVUNL to increased risk

The Jawaharpur project is owned by Jawaharpur Vidyut Utpadan Nigam Limited (JVUNL) which is a 100% subsidiary company of UPRVUNL. Both projects are designed and constructed by Korean company Doosan and both will use efficient “Flue Gas Desulphurisation (FGD) Plants” as mandated by Ministry of Environment, Forest, And Climate Change (MoEFCC).

UP Rajya Vidyut Utpadan Nigam (UPRVUNL) is constructing two large new power stations using Super Critical boiler technology. One is the Obra “C”, 2 x 660 MW project, and the other is the Jawaharpur, 2 x 660 MW project. The Jawaharpur project is owned by Jawaharpur Vidyut Utpadan Nigam Limited (JVUNL) which is a 100% subsidiary company of UPRVUNL. Both projects are designed and constructed by Korean company Doosan and both will use efficient “Flue Gas Desulphurisation (FGD) Plants” as mandated by Ministry of Environment, Forest, And Climate Change (MoEFCC).

As a result of using FGD plants, the flue gas in the chimneys will have a low temperature and it will be highly corrosive. In order to ensure that the chimneys would be durable and reliable, UPRVUNL had specified the use of high quality, well-proven chimney lining system from the United States, which has been used by power stations worldwide. For the case of Obra “C”, UPRVUNL’s technical specification was watertight and the contractor has now placed an order on the supplier of the American lining system. For the case of Jawaharpur, using some deficiencies in the specification text, the contractor is pushing for the use of a Chinese manufactured “copycat” system, which does not offer the required quality and performance track record.

UPRVUNL’s desired US manufactured lining system has a proven service life of more than 30 years and it requires little or no maintenance. The supplier of this product offers his technology with a complete 10-year guarantee. The Chinese manufactured copycat system being pushed now for Jawaharpur will likely require frequent maintenance and repair and it will reduce the availability of the chimney by about 450 days over the 30-year life of the power station. However, considering the fact that his liability period for the Jawaharpur power station is only 18 months, this reduction in quality does not seem to be the contractor’s concern.
