Renewable Energy Solutions
To date, Marubeni has invested and gained experience in a wide varieties of renewable energy projects ranging from solar, offshore wind, onshore wind, hydropower, biomass and geothermal.
On most of these projects, Marubeni is active from construction stage and remain actively involved during operation and until decommissioning or handover to local partners.
Development and Construction Experience
Marubeni was the first Asian company to invest in UK offshore wind projects and has gained development, construction and operations experience through these as well as from previous investments into renewable developers.
Marubeni has been responsible for leading the development of Japan’s first commercial offshore wind farm – the Akita Offshore Wind project. To date, the company had responsibility for managing the project’s environmental studies, permitting, conceptual design, grid connection, project management and procurement. The project will begin construction during 2020, with Marubeni Power Systems Corporation (MPSC) providing a multi-disciplinary team to undertake the construction management.
Offshore Transport and Installation
Marubeni has been the majority shareholder in Seajacks International since 2012. Seajacks owns and operates five self-propelled jack-up vessels, including class-leading Scylla which has a 1,200 tonne lift capacity. The company provides safe and efficient offshore solutions around the world, in both the offshore wind and oil & gas sectors. For offshore wind, Seajacks provides services for the transport and installation of foundations and wind turbines, as well as substation hook-up and commissioning works and operations and maintenance activities.
Seajacks have successfully completed multiple offshore wind projects in Europe and more recently expanded its footprint in the growing Asian offshore wind markets including Taiwan and Japan.

Seajacks provides Marubeni with unique insight and understanding of this critical part of an offshore wind farm, ensuring that these aspects can be considered from the early stages of a project.
Floating Offshore Wind
Marubeni has significant experience of developing, constructing and operating floating offshore wind farms. Through the Fukushima and Kita-Kyushu projects in Japan, as well as development projects in Europe, Marubeni has experience of several different floating foundation types as well as a floating offshore substation, with operational experience dating from 2013. This knowledge allows the company to consider the most suitable technologies for the specific conditions and requirements of future projects.

Marubeni has vast experience building and operating geothermal energy projects with past involvements in Costa Rica and Philippines and current construction of Rantau Dedap in Indonesia.
In Europe Marubeni is currently developing a geothermal energy project in the South East Molasse Basin of Germany. With an expected thermal power output of over 100MW, the project is looking to deliver renewable heat and electricity to the local communities for over 50 years. In parallel, Marubeni is looking to make other geothermal project investments in other parts of Europe suitable for geothermal development.
Operations, Maintenance, Services and Asset Management
Marubeni brings strength to renewable projects through its Marubeni Power Asset Management (MPAM) business, headquartered in Hong Kong. MPAM provides asset management services to ensure the economic and efficient operation of both in-house and third-party power plants.
Marubeni’s services business, PIC, provides technical professionals and services including commissioning, start-up, O&M training and documentation for power plants can support projects worldwide from its headquarters in Atlanta, Georgia.
EPC and IPP Experience
Marubeni’s experience of developing and constructing power plants on an engineering, procurement and construction (EPC) basis dates from the 1970s. Since that time, the company has delivered over 112GW of projects in many parts of the world, utilising generation technologies including gas, hydropower, geothermal, cogeneration and wind. This long-established business provides valuable understanding of the technical and commercial project delivery required to safely deliver large capital projects.
Marubeni has been an independent power producer (IPP) for over 25 years, and currently has a portfolio capacity of 12.6GW (net) across 18 countries, with a knowledge of many different regulatory, permitting and operating models. This is made up of a variety of generation sources including gas, LNG, hydro, coal, oil, geothermal, biomass, wind and solar. The company’s first renewable IPP investment was in 1997. Notable renewable investments include onshore wind projects in Portugal and USA, geothermal in Indonesia, hydropower in Philippines and more recently a 1.1GW photovoltaic solar project in the Middle East.
Marubeni has announced that the company will half its coal-fired power IPP generating capacity by 2030 whilst expanding the proportion of renewable generation from the current 10% to 20% by 2023.
