SPX Corporation, through its subsidiary SPX Heat Transfer, has been awarded a contract of approximately $18m to design and manufacture 20 new feedwater heaters for two new coal-fired power plants being built in the Indian state of Bihar.

The formal agreement was signed between SPX Heat Transfer and Bharat Heavy Electricals Limited (BHEL), which has been tasked with the design, engineering, construction and installation of the Barh Phase II projects that are being built for NTPC.

Units 1 and 2 of Barh II project will have a capacity of 660MW each and are scheduled to be commissioned in March 2012 and January 2013, respectively.

Plans call for SPX Heat Transfer to manufacture the feedwater heaters at its main facility located in Tulsa, Oklahoma and then ship the units to India.

The two-unit, 1,320MW Barh II extension will deliver power mostly to north, west and east India with six 400KV electrical substations linking Barh to Kahalgaon, Sasaram and Biharsharif.

The plant uses supercritical steam generation, with water instantly being converted into steam without passing through the boiling phase.
