Alstom wins contract via NASL to retrofit air quality control system in India

The retrofit will reduce particulate emissions from Captive power plant to below current national environmental norms  

Alstom, a world leader in the supply of equipment and services for electricity generation, has announced in India that it has been awarded a contract via its joint venture company NASL worth approximately 20 million (approx Rs. 120 cr.) from the National Aluminium Company Ltd.(Nalco) to retrofit the electrostatic precipitators (ESPs) at five 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 Indias 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, APILs scope of work would be Rs 74.16cr. The contract 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 has been associated with Nalco for almost three decades. Alstom executed its first project with Nalco in 1982 with the supply of a fume treatment plant for Nalcos Aluminium Smelter. Since then, Alstom has supplied fume treatment plants for all potlines expansions at the Angul plant.

ESPs have been used widely to control particulate emissions. ESPs are often the most cost-effective solution due to high removal efficiencies in combination with robustness and low maintenance costs. A large majority of industrial and thermal power units in India are equipped with ESPs. More stringent emission requirements and more challenging conditions due to fuel switching and other process changes result in a need for improved collection efficiency and ESP retrofit. As the world leader in air quality control systems with experience spanning more than 1000 ESP upgrade projects worldwide, Alstom is well positioned to serve this growing sector in India.

"This contract represents one of the largest ESP retrofit contracts in India to date. It is a significant step forward for NASL and Alstom and clearly reinforces the markets faith in our leading air quality control systems and services, said François Carpentier, Head of Alstom Power in India.
