Marubeni Corporation (“Marubeni”), in partnership with Mitsubishi Heavy Industries, Ltd. (MHI), has been jointly awarded orders for three large-scale combined cycle electric power projects in Korea; the 2nd Pyeongtaek Combined Cycle Power Plant, the Dongducheon Combined Cycle Power Plant and the Ulsan 4 Combined Cycle Power Plant. They will have a collective power generation capacity of around 3,800MW.

The 2nd Pyeongtaek power plant will have generation capacity of nearly 950 MW and is being built in Gyeonggi-do by Korea Western Power Co., Ltd. (KOWEPO), a subsidiary of Korea Electric Power Corporation (KEPCO). Marubeni has received an order, jointly with MHI, for two M501J (J-Series) gas turbines(*), one steam turbine and generators for the plant.

For the near 1,900 MW Dongducheon power plant, Marubeni received an order, also jointly with MHI, consisting of four J-Series gas turbines, two steam turbines and generators. Dongducheon Dream Power Co., Ltd., an IPP jointly established by KOWEPO, Samsung C&T Corporation and Hyundai Development Company, is building the plant in Gyeonggi-do. Marubeni and MHI will deliver the core components to Samsung C&T and Hyundai Development.

For the near 950 MW Ulsan 4 power plant, operated by the Korea East-West Power Company (EWP), a subsidiary of KEPCO, in Ulsan Metropolitan City, Marubeni received an order jointly with MHI and Daelim Industrial Co, Ltd. for engineering, procurement, delivery of the equipment, including two J-Series gas turbines, a steam turbine and generators, and the construction and installation work, on a full turn-key basis.

In these projects, Marubeni believes that the extensive experience of Marubeni and MHI, combined with technical reliability as well as the high thermal and economic efficiency of the equipment, are highly appreciated by the Korean power sector and led to the successful receipt of these orders.

Previously, in 2010, Marubeni and MHI jointly received an order for two sets of steam turbines and generators, 1,000MW each, for ultra-super-critical-pressure coal-fired power generation units for unit #9 and #10 of EWP’s Dang Jin Coal Fired Power Plant. These new orders are the first received from the Korean power sector since then.

The Korean power sector has shown steady growth with many new and large scale projects under planning and development. Marubeni, with its strong presence in the market, intends to actively pursue further opportunities in various power plant projects together with MHI.

(*) The M501J Gas Turbine is a 60 hertz J-Series gas turbine developed by MHI, incorporating proprietary technologies. This new turbine is able to withstand temperatures 100 degrees higher than the 1,500°C-class G-Series gas turbine, which was the top-of-the-line until now. This gas turbine achieves a rated power output of about 327MW and an unprecedented 470MW in gas turbine combined-cycle (GTCC) output (1 gas turbine - 1 heat recovery steam generator - 1 steam turbine combination). This gas turbine has also achieved over 60% in gross thermal efficiency, the world's highest level in GTCC applications. The M501J gas turbine will significantly contribute to easing environmental burdens, as its GTCC power generation will be able to achieve CO2 emissions approximately 50% lower than with conventional coal-fired power generation.
