New Delhi: Mitsubishi Heavy Industries, Ltd. (MHI) has received two orders in succession for core components of a total of five sets of a 660-700 megawatt (MW) supercritical-pressure* coal-fired boiler and steam turbine.

MHI received the two orders through two joint venture companies established by L&T and MHI in 2007: L&T MHI Boilers Private Limited (LMB) and L&T MHI Turbine Generators Private Limited (LMTG). MHI will manufacture the core components of the boilers and turbines, including pressure-containing boiler components and steam turbine rotors, and supply them to the two companies.

These are to be installed in high-efficiency coal-fired power plants to be built by two independent power producers (IPP) in India. Delivery of two sets for a power plant in Punjab, currently being built by Nabha Power Limited which is wholly owned by Larsen & Toubro Limited (L&T), is slated to begin in the middle of this year, while shipment of the other three sets for a power plant in Uttar Pradesh, which Sangam Power Generation Company Ltd. plans to build, is scheduled to begin in late this year

Mitsubishi Electric Corporation is responsible for generators. Through the two JVs with L&T, to date MHI has received 4 orders for a total of 10 boilers and 5 orders for 12 steam turbines. The new manufacturing plants of both JVs have already commenced full-scale operation.

Going forward MHI will continue aggressive marketing activities for its high-efficiency supercritical-pressure boilers and turbines in India together with its two JVs and L&T.

Construction of the supercritical-pressure coal-fired power plant in Rajpura, Punjab, is part of a power generation capacity expansion program of Punjab State Power Corporation Ltd. (PSPCL, formerly Punjab State Electricity Board) to ease electricity shortages in eastern Punjab, where rapid growth of manufacturing industries continues. Nabha Power Limited, a subsidiary of L&T , has already signed a power purchase agreement (PPA) with PSPCL.

The power plant to be built in Karchana, Uttar Pradesh, is similarly part of that state's power generation capacity enhancement program. Sangam Power Generation, which is based in Lucknow, the state capital, is a subsidiary of Jaiprakash Power Ventures Ltd. (JPVL), an affiliate of the Jaypee Group, an infrastructure conglomerate in India. This is the second boiler/turbine set order placed to LMB and LMTG for JPVL's power plants.

*Supercritical turbines are engineered to operate at steam pressures above water's critical point: 22.1MPa (about 220 times greater than normal atmospheric pressure) and 374.2°C (705.2°F/647.15°K). In actual use, they will operate in an environment of about 250 atm.
