Alstom has been awarded a contract, via its joint venture company NASL, worth EUR20 million (US$27 million) from the National Aluminium Company (Nalco) of India to retrofit the electrostatic precipitators (ESPs) on the five units of its captive power plant in Angul, Orissa.

The ESPs at Angul were originally supplied by BHEL and commissioned between 1985 and 1989.

The upgrade will reduce particulate emissions from the plant to well below the 150 mg/Nm3 requested by the Environment Pollution Control Board, allowing Nalco to conform to India’s environmental requirements.

The contract scope includes the design, supply and commissioning of the mechanical and electrical components of the ESPs, including the control system and the ash handling system.
 
The contract will be executed through Nalco’s local services partner, NASL, a joint venture company of Alstom and National Thermal Power Corporation.
 
The first unit is expected to be commissioned in 2012, with the fifth one being completed in 2014.
 
Alstom has been associated with Nalco for almost three decades, executing its first project in 1982 with the supply of a fume treatment plant for Nalco’s aluminium smelter.
