EPC: Engineering, Procurement and Construction

Our Strengths

Top Class Global IPP Portfolio with Rich Sales & Marketing Knowledge and Worldwide Strongholds for Project Development & Asset Management

In the power generation business, Marubeni delivers safe & stable supply of power by taking a leading role throughout the entirety of the projects in which it participates. From development to construction, and finally to operation & maintenance, Marubeni leverages its industry expertise, fostered by a wealth of knowledge and experience in EPC and project finance, fully supported by a worldwide network of strongholds for project development & asset management. Marubeni has built an optimum IPP/IWPP asset portfolio in a diverse range of regions of the world. Most of the projects are guaranteed under long-term power purchase agreements which provide a stable profit foundation. In Japan and overseas, our total net generation capacity is 12,609MW (as of the end of March 2020) which is comparable to leading international IPP players.

Proactively Promoting and Increasing Renewable Energy Projects to Contribute to a Low-Carbon Society

Marubeni recognizes that climate change is a global issue that affects both environmental and social sustainability. In accordance with the Marubeni Group’s sustainability management policies, and recognizing the importance of counteracting the effects of climate change, Marubeni will reduce the greenhouse gas emissions from its power generation portfolio by both cutting coal-fired power generation capacity in half*1 and no longer entering into any new coal-fired power generation business as a general principle. Furthermore, Marubeni will expand its renewable energy generation business*2 in addition to deploying innovative technologies to increase the efficiency of its portfolio assets, proactively promoting the reduction of its environmental impact.

1 We will cut our net generation capacity of coal-fired power generation (approximately 3GW at the end of FY2018) in half by 2030.

2 We will increase the ratio of power generated by renewable energy sources in its own net power supply to approximately 20% by 2023.

A Robust Track Record of Overseas Power EPC Projects and Unique EPC Contract Knowledge and Experience

Since Marubeni began supply and construction of overseas power projects in the 1960s, we have proactively engaged with Japanese and multi-national major equipment manufacturers, and compiled a robust track record of power generation, T&D and S/S EPC projects all over the world. Such expertise as an EPC contractor creates a synergy-effect with IPP/IWPP development. Furthermore, in the offshore wind turbine installation business, we have expanded into the Asian market in addition to our existing bases of operation in Europe.

Extensive Experience in Power Aggregation and Retail

Through SmartestEnergy Ltd., a company established in the U.K. in 2001, we are conducting aggregation/whole-procurement and retail sale of primarily renewably generated power to the U.K. power market. We have launched this business in the United States and Australia as well. Domestically, in 2000 when the Japanese power retail market became deregulated, Marubeni established Marubeni Power Retail Corporation as a PPS (Power Producer and Supplier) and entered the market. This allowed Marubeni to, among other things, internally balance the supply and demand of power retail sales through power sourced from Marubeni-owned plants. Marubeni has thus accumulated ample skill in supply-and-demand management and has an impressive track record of power projects.

Promoting Community-Based Power Services to Support the Resolution of Regional Social Subjects

Marubeni promotes de-centralized power sources in regions of Africa that do not have access to electricity through WASSHA Inc, a company which rents solar panels and chargeable lanterns to supply portable power to various regions of Tanzania, and through Azuri Technologies, a company that provides solar home systems*3 in various African countries. Furthermore, we have become aware of growing interest in energy autonomy with renewable energy and de-centralized power sources, and as such we have established Marubeni Ina Mirai Denki Corporation in Ina City, Nagano, Japan. Moving forward, we will expand community-based multi utilities services that will assist development in regional societies.
