Mae Moh Lignite-Fired Power Plant

Project name Mae Moh Lignite-Fired Power Plant
Region Lampang Province, Thailand
Customer Electricity Generating Authority of Thailand (EGAT)
Contract price Approx. JPY 120 billion

This full turnkey project order has been jointly received from EGAT by Marubeni and ALSTOM, a major French heavy machinery manufacturer.
The project is for the new construction of a power plant that will replace the existing Units 4 – 7 of the Mae Moh Lignite-Fired Power Plant that were previously delivered by Marubeni. This unit will produce electricity from lignite mined from a neighboring coal mine. ALSTOM will supply the main equipment while Marubeni will procure the auxiliary equipment and undertake the civil and installation work. It is planned that an eco-friendly power plant will be built through the use of ultra-supercritical technology.  Our advanced technology that makes it possible to overcome the difficulty of burning lignite, which has a higher degree of calcium oxide than normal coal, led to our being awarded this project.

In recent years, the company has been consecutively awarded and has completed thermal power plant projects from EGAT. With the receipt of this Mae Moh project, the total installed capacity of projects delivered by Marubeni in Thailand over the past 50 years will reach 10,300 MW.


Thai Binh Coal-Fired Thermal Power Plant

Project name Thai Binh Coal-Fired Thermal Power Plant
Region Thai Binh Province, north of Vietnam
Customer Vietnam Electricity
Contract price Approx. JPY 90 billion
Generation capacity 600 MW (300MW×2)

In December 2013, Marubeni was awarded a full turnkey project for delivering a coal-fired thermal power plant along with a full set of facilities. The company acquired the order through an international competitive bid for a yen credit supply by JICA. As a result of the company’s experience in Vietnam, including the Nghi Son project currently under way, and the company’s competitiveness in pricing and performance, the company was highly evaluated during the bidding process. Similar to the Nghi Son project, breakout procurement will be performed for this project. Civil engineering work, including foundation improvement, has been ordered for a major Japanese civil engineering company, and orders for the steam turbine, generator, and environmental equipment, such as the electrical precipitator and exhaust gas desulfurizer, have been placed with major Japanese manufacturers. In addition, as Vietnamese anthracite, which is difficult to burn, will be used as the fuel, an order has been placed for a highly efficient anthracite boiler with a North American boiler manufacturer that possesses state-of-the-art technology. Because this is a large-scale project that requires advanced project management capabilities and technologies, it is receiving attention as an important project that will contribute to the stable power supply and economic development of northern Vietnam.

The Emergency Purchase Project of Gas Turbine Generators for Post-earthquake Restoration Efforts

Acquisition of PIC (U.S.)
Project name The Emergency Purchase Project of Gas Turbine Generators for Post-earthquake Restoration Efforts
Location Higashi Niigata Thermal Power Station in Seiro-machi, Kitakambara-gun, Niigata, Japan
Client Tohoku Electric Power Co., Inc.

This project was an emergency purchase to back up the power supply for the restoration efforts after the Great East Japan Earthquake on March 11, 2011.

We performed the contract for two units of mobile gas turbine power generator (unit output capacity: 25 MW/@ unit class) that were to be installed at the site of Higashi Niigata Thermal Power Station on turnkey contract (that covers engineering, procurement, construction, commissioning, and temporary O&M) basis.

We made full use of the advantage of Marubeni's capabilities as a leading trading company and accomplished exceptional urgent delivery and installation with the emergency measures. Actually, we made a special arrangement to deliver 2 units of the gas turbine from GE in U.S.A. and Hungary by aircraft, instead of normal ocean shipment. And, we successfully completed the installation and contract in the unusually short period of three months from order placement and one month from the delivery of the units at the site.

The units were not only contributed to post-earthquake restoration but also they are now still being utilized as back up emergency power supply for the peak power demand.

    *Full turnkey contract:
    A method of contracting everything from installation, civil work, assembly, start-up supervisor, and warranty responsibilities; this indicates the conducting of all work until the facility is ready to run, up to the "turn of the key."

    *Ultra-supercritical-pressure coal-fired thermal power generation:
    A steam power generation method in which the boiler equipment operates at least at a steam temperature of 593 °C and at a steam pressure of 24.1 MPa
    This method improves the power generation efficiency by generating steam at ultra-high temperature and pressure to drive steam turbine generators that are designed for these conditions. This leads to reducing the amount of CO2 emissions during power generation and thus helps lower the environmental load.

    *EPC (Engineering Procurement & Construction):
    A form of contracting arrangement that covers everything from the design of the plant, delivery of equipment, procurement of spare parts and materials, and the construction and installation of the plant itself.

    A method to procure power plant equipment dividing into components and systems from different manufacturers; this enables each manufacturer to concentrate to its own product and to provide it at a more competitive price. As a result, the overall price of the plant comes to be competitive.
    Because of the complexity of risk control including interface coordination, it requires more sophisticated project management and implementation capabilities.
