Our Strengths

Active development of renewable energy generation projects to help realize a low-carbon society

In pursuit of a low-carbon society that mitigates climate change as a sustainable development goal, we are expanding our renewable energy generation business globally, including offshore and onshore wind power, solar power, biomass, and hydropower. We are also working on reducing the environmental impact through the reduction of our coal-fired power generation projects*4. We will consider the adoption of new technologies aimed at reducing CO2 emissions.

4 We will cut our net generation capacity of coal-fired power generation (approximately 3GW at the end of FY2018) in half by 2025.

Vast experience in wholesale and retail power sales, diverse track record in the electric power services business and new businesses

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 businesses and new businesses.
In addition to expanding its distributed power generation business, Marubeni is strengthening and expanding its initiatives in the power service business field and new business fields utilizing DX, including online sales of battery storage systems, energy management services for consumers such as optimal EV charging strategies, and monitoring and analysis technologies for efficient use of transmission lines.

Strong Regional marketing capabilities in Japan and Overseas, industry Top-Class IPP*5 Track Record, EPC Coordination Capabilities, excellent Asset Management System

In the power generation business, Marubeni delivers a safe and 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 and 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 11,550MW (as of the end of March 2023) which is comparable to leading international IPP players.
