Alstom, a supplier of electricity generation equipment and services, has announced in India that it has bagged a contract via its joint venture company NASL worth approximately €20 million (approx Rs 120 cr) from the National Aluminium Company (Nalco) to retrofit the electrostatic precipitators (ESPs) - a cost-effective solution widely used to control particulate emissions - at 5 units of its captive power plant in Angul, Orissa.
The ESPs at Angul was originally supplied by BHEL and the units were 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, thus allowing NALCO to conform to India’s environmental requirements.
The contract scope includes the design, engineering, supply, erection and commissioning of the mechanical and electrical components of the ESPs, including the control system and the ash handling system. Out of the entire aforesaid contract, APIL’s scope of work would be Rs 74.16 crore.
It will be executed through, NASL, a joint venture company of Alstom and National Thermal Power Corporation (NTPC). The first unit is expected to be commissioned in 2012, with the fifth one being completed in 2014.
Alstom executed its first project with Nalco in 1982. "This contract represents one of the largest ESP retrofit contracts in India to date,” said François Carpentier, Head of Alstom Power in India.
