Reliance Infrastructure Ltd (RInfra) has emerged as the lowest bidder in a ₹567-crore EPC tender, floated by NTPC for setting up a system, which will remove sulphur dioxide from the exhaust gases of the Jhajjar power plant, sources said.

The national power company runs a 1,500-MW thermal coal-based power plant at Jhajjar, Haryana. The plant has three units of 500 MW each.

When thermal coal gets burnt at a power plant, sulphur dioxide along with other hazardous chemicals are emitted in the exhaust gases, which are also called flue gases. RInfra will install the Flue Gas Desulphurisation (FGD) system at the plant. The FGD system will help curb the pollution and improve the air quality around the plant.

Considering the dipping air quality in the vicinity of coal-based power plants and the resultant health hazards, the Union Ministry of Environment, Forest and Climate Change had notified in 2015, the revised standards for emissions to be met by thermal power plants. Meeting of these standards requires comprehensive retrofits of power plants with FGD system in the operating units as well as units under construction.

RInfra has emerged as the lowest bidder amid stiff competition from other EPC players such as BHEL, L&T and Mitsubishi Hitachi Power Systems, sources said.

The overall schedule for the project is 20 months from the date of allotment for the first unit with subsequent units at three months interval.
