On March 9, 2015, Marubeni Corporation (“Marubeni”), in partnership with ALSTOM Power Systems SA and ALSTOM (Thailand) Limited (“ALSTOM Group”), jointly signed an EPC contract with the Electricity Generating Authority of Thailand (EGAT) for the construction of a new unit for Mae Moh lignite-fired power plant. This unit will replace the existing Units 4-7 and will produce about 600MW of electricity, having an EPC contract value of over 1.0 billion USD dollars (equivalent to over 120 billion yen).
Located in the northern Thai province of Lampang, this new unit will produce electricity from local lignite mined from a neighboring coal mine. Use of ultra-supercritical conditions for the boiler will significantly reduce its environmental footprint and allow the plant to meet strict environmental standards. The scope of Marubeni and ALSTOM Group for this project includes engineering, procurement, construction, and commissioning. ALSTOM Group will supply the main equipment such as the ultra-supercritical boiler, steam turbine, and generator, while Marubeni is in charge of supplying the balance of plant equipment and civil / installation works.
At present, Mae Moh lignite-fired power plant Units 4-13, originally supplied and constructed also by Marubeni and Alstom group, are under operation. Higher efficiency as well as state-of-the-art technology to overcome the difficulty of burning lignite with a high degree of calcium oxide (CaO) led to the award of this project, in addition to the Consortium’s extensive experience in executing EPC projects in Thailand, price competitiveness, and project implementation capacity.
In the recent decade, Marubeni has consecutively executed the Chana Combined Cycle Power Plant Units 1 and 2, Bang Pakong Combined Cycle Power Plant Unit 5 and Wang Noi Combined Cycle Power Plant Unit 4 for EGAT. With this Mae Moh Replacement Project, the total installed capacity of projects delivered by Marubeni in Thailand over the past 50 years will surpass 10,300MW.
The Thailand power sector shows steady growth where new and large scale projects are under planning and development to meet rising demand. Marubeni, with its strong presence in the market, will continue to actively pursue further opportunities in various power plant projects.
