Marubeni, in partnership with Toshiba Corporation, was awarded the Lumut Balai Geothermal Power Plant project with an overall capacity of approximately 55 MW by Pertamina Geothermal Energy in 2014. The project was financed by yen loan from JICA. This was one of the new power source development projects with an overall capacity of 10,000 MW that was planned by the Government of Indonesia from 2010 to 2014 in response to the rapid increase in demand for electricity in Indonesia which, it is said that, has the world’s largest potential for geothermal power generation. By building a geothermal power plant with low environmental impact in Muara Enim Regency in South Sumatra Province, Marubeni contributed to stable supply of power in Indonesia.

Marubeni was awarded the full turn-key (EPC) project of Bibiyana Combined Cycle Power Plant project with an overall capacity of approximately 400 MW by the Bangladesh Power Development Board (BPDB). This project was financed through buyer’s credit from Japan Bank for International Cooperation (JBIC). This was the full turn-key contract including delivery of a set of power generation equipment and construction and installation work. The gas turbine (GT), which is the main equipment, was supplied by Mitsubishi Heavy Industries, the gas turbine generator (GTG) was supplied by Mitsubishi Electric, and the steam turbines and generator was supplied by Fuji Electric. The project was completed in 2021. In 2023, Log-Term Service Agreement was concluded with BPDB, and since then, we have been providing remote monitoring service of the power plant and regular scheduled maintenance services for key components such as GT and GTG to maintain the safe and efficient plant operation.

We were awarded Long-Term Service Agreement for the Bheramara Combined Cycle Power Plant by North-West Power Generation Company Limited (NWPGCL), a Bangladesh state-owned regional power and electric company. The contract was signed in August 2018.
This long-term service agreement is to perform remote monitoring of the power plant as well as scheduled maintenances for key components (including gas turbine, steam turbine, and generators) for 6 years in collaboration with Mitsubishi Heavy Industries, who is the manufacturer of the main equipment.
Bheramara Combined Cycle Power Plant is located in Bheramara of the Kushtia District, about 150 km west from Dhaka, and has a capacity of approximately 414 MW. We are performing scheduled maintenances including replacement of the required parts to prevent degradation of power generation efficiency and to ensure stable operation of the power plant.

In this project, the consortium of Marubeni and VISCAS manufacture, deliver, and install underground power cables for Abu Dhabi Transmission & Despatch Company (TRANSCO) of the United Arab Emirates, and it was completed in August 2021. This project connects Sas Al Nakheel Island, where the power plant is located, to Mahawi, where new capital-related facilities will be constructed, and to the Musaffah industrial area, with 400 kV high voltage underground cables that has a total length of approximately 200 km. Abu Dhabi is in process of the national project to relocate some of its capital functions from the small Abu Dhabi Island to Mahawi. With the completion of our project, it became possible to remove the existing overhead power lines which had been an obstacle of the national project.
The consortium has also successfully completed projects to install 400 kV high voltage underground cables (with the total length of 80 km) to supply power to Saadiyat Island near central Abu Dhabi, where Louvre Abu Dhabi is located, and another 132 kV high voltage submarine cables (with the total length of 26 km) to supply power to Sir Bani Yas Island, the resort island at the west of Abu Dhabi.

This was the full turn-key project to construct the 6th unit within the existing Olkaria 1 Geothermal Power Station. It was Marubeni’s first geothermal power plant project in Africa. The main equipment such as steam turbines and generators are procured by Fuji Electric. The project was completed in July 2022. The project was financed by yen loan from Japan International Cooperation Agency and loan from European Investment Bank.
Geothermal power emits only a small amount of greenhouse gas and is capable of generating stable power regardless of weather. It generates and accounts for approximately 46% of the total power in Kenya, making it an important base-load power source.
Kenya is seeing the growth of peak power demand at an average of 5% every year. Through the fulfillment of this contract, Marubeni will respond to rapid increase of demands for electricity in Kenya and contribute to the country’s economic growth.

In April 2016, Marubeni founded Akita Offshore Wind Corporation (hereinafter, “AOW”), a special purpose company. With the investment and participation of other 12 partners, AOW has started a project to construct, maintain, and operate the pile-driving offshore wind farm and the on-shore power transmission and substation facilities, which is Japan’s first commercial-base large-scale offshore wind power generation project.
Signing Construction Management Agreement in February 2020, we were in charge of construction management (program, budget, safety, quality control, etc.) and achieved overall commencement of commercial operation at the end of January 2023.
Offshore wind power generation is expected to become the mainstream of renewable energy. We will continue to actively seek the possibilities to participate in construction and operation businesses of domestic and overseas offshore wind power generation, as well as to contribute to the prevention of climate changes in the world.

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. 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 were being utilized as back up emergency power supply for the peak power demand.
