MHPS's JVs in India Receive Orders for 2 Sets of Supercritical-pressure Coal-fired Boilers and Steam Turbines
-- To be Installed at Shree Singaji Thermal Power Plant of Madhya Pradesh Power Generating Co. --

No. 037

Yokohama, March 9, 2015 -- L&T-MHPS Boilers Private Limited and L&T-MHPS Turbine Generators Private Limited, two joint venture companies of Mitsubishi Hitachi Power Systems, Ltd. (MHPS) established in India, have received orders for two supercritical-pressure (Note) coal-fired boilers (output: 660 megawatts [MW] each) and two steam turbines, respectively. The boilers and turbines on order will be installed in Unit 1 and 2 of Shree Singaji Thermal Power Plant, which Madhya Pradesh Power Generating Company Limited (MPPGCL) of India is newly constructing. Unit 1 and 2 are scheduled for completion in April and August 2018, respectively. The orders bring the total number of supercritical-pressure boiler and steam turbine ordered from India to MHPS to 13 units, respectively.

L&T-MHPS Boilers and L&T-MHPS Turbine Generators, joint ventures between MHPS and Larsen & Toubro Limited (L&T), a leading construction firm and heavy machinery manufacturer in India, will manufacture and supply two sets of supercritical-pressure boilers, steam turbines and generators, which are major equipment of supercritical-pressure power plants. L&T-MHPS Boilers will be also responsible for the boilers' installation and commissioning work at site. MHPS will provide the joint ventures with their core components including the boilers' pressure parts and the turbines' large-size rotor blades.

The plant will be constructed by MPPGCL near the city of Khandwa in Madhya Pradesh state in central India. When the new facility goes on stream, it will respond to the region's robust power demand.

As India has marked economic development over recent years, power supply has been unable to keep pace with rapidly increasing demand, resulting in serious power shortages in some regions. To remedy this situation, a host of new plans have been launched to develop large-scale power sources. Construction of the Shree Singaji plant is a part of those initiatives.

MHPS has a strong track record in supercritical-pressure and ultra-supercritical-pressure coal-fired power plants - plants that not only realize outstanding efficiency in power generation but also help curb CO2 emissions.

Going forward, the company will continue to apply its superior technologies to enable stable power supplies and contribute to reducing environmental loads in India as well as in a broad palette of other countries and regions where demand for coal-fired power generation plants is expected to increase.

  • Under normal atmospheric pressure (1 atm), water boils at 100°C (212°F/373°K) and the temperature and pressure go no higher. When increased pressure is applied, however, the boiling point rises beyond 100°C; and if pressure is increased further and takes the water temperature to 374°C/22.1 megapascals (approx. 220 atm), water no longer boils but rather vaporizes. This is referred to as water's "critical point." Supercritical pressure is defined as the state when the pressure level has been increased to roughly 250 atm, driving the water temperature to 566°C; and ultra-supercritical pressure refers to the state when water's temperature rises to 593°C. In recent years, owing to their enhanced power generation efficiency, demand has been increasing for supercritical-pressure and ultra-supercritical-pressure boilers and steam turbines.
