ORIX is involved in various businesses including energy-saving services and electric power retailing. We contribute to efficient energy use and supply by providing products and services aligned with customer needs that save energy and reduce energy costs.

Efficient Energy Use

Energy-saving services

Energy-saving services seek to realize energy savings and reductions in CO2 emissions through increased productivity. The services are offered when our customers update or establish new production facilities in factories and buildings.


  1. Cooperation of the customer, who is our joint applicant, is required for application procedures and asset management.
  2. This service does not guarantee the attainment of subsidies. We may be required to return the subsidy if we have not complied with the application guidelines.
    Because subsidies come from public funds, there are restrictions on property disposition and reporting obligations, and unapproved changes in plans or failure to achieve certain results can lead to demands to return subsidies.
    In the case of a joint application, if ORIX returns a subsidy, the customer will be required to pay the amount equivalent to the subsidy returned (unless ORIX is liable for the causes of the return of subsidy).

For Agatsuma Biomass Power Plant, please refer here.
At Soma Coal and Biomass Power Plant and Hibikinada Coal and Biomass Power Plant, biomass accounts for approximately 30% or more of the total amount of fuel; this results in lower CO2 emissions compared to coal-fired power plants in the same class and so decreases the environmental burden. Using such world-class environment friendly facilities, ORIX is engaged in advanced measures for a sustainable future.
Through the adoption of safe and secure combustion methods at Agatsuma Biomass Power Plant, Soma Coal and Biomass Power Plant, and Hibikinada Coal and Biomass Power Plant, ORIX will generate and supply electricity in a stable manner that is unaffected by the seasons or weather conditions.

Joint Research into a Tracking System

Together with the School of Engineering at the University of Tokyo, ORIX has started joint research into a tracking system that leverages blockchain technology to prove the production site and history of renewable energy-based electric power, from supply to consumption.

In recent years, as social interest is increasing in the achievement of a carbon-free society and ESG investment, global movements at corporations and local municipalities aiming for RE100, whereby 100% of consumed power is renewable energy. However, an issue had arisen as the source of electricity was unable to be determined for conventional power supply services meaning that the site of production of renewable energy could not be proven. This was because the power produced at power plants is centralized on a power grid before being sent to consumers such as corporations and individuals.

In order to resolve such issues, ORIX and the University of Tokyo will conduct demonstration tests on a system that uses power transaction and GPS data to track various aspects of power generated from renewable energy, including its production site, source of power, production time, and suppliers. Matching verification of distributed networks that are simultaneous/commensurate*1 with multiple power sources such as solar power generators and general households, and multiple consumption sites such as offices, factories and electric vehicles will also be implemented. ORIX and the University of Tokyo also intend to develop a system for minimizing the geographical power transmission distance between multiple generation sites and sites of consumption, will be developed to promote the local production and consumption of renewable energy.

As this will lead to users purchasing power from local power sources, it is hoped that it will contribute to vitalizing local economies while also reducing transmission loss and enabling the efficient use of power. In the future, ORIX will work to develop comprehensive power networks including demand response*2, virtual power plants (VPP) using electric vehicles, as well as coordinating with the disaster systems of local municipalities with the aim of also applying this technology to social systems, such as utilizing electric vehicles as emergency power sources in areas affected by disasters.

Ahead of anticipated changes in the social environment going forward, both ORIX and The University of Tokyo hope to contribute to the popularization of well-balanced renewable energy and the realization of a distributed energy network society.

  1. As it is difficult to store electricity as it is, the supply and demand volume must constantly be matched in terms of total volume over 30 minutes.
  2. While the volume of power supplied is conventionally adjusted to match the amount of energy demand, Demand response refers to achieving simultaneous/commensurate amount by having the user adjust the amount of demand.

Participating in a demonstration project to build a virtual power plant (VPP)

ONE Energy is a member of the Virtual Power Plant Construction Demonstration Project*, which is headed by Tokyo Electric Power Company Holdings, Inc. Virtual power plants (VPP) control the charge and discharge of storage batteries installed at the homes of private customers, commercial facilities and factories to make them function like a single power plant. VPPs make efficient use of small distributed energy resources, and provide the economic benefit of being cheaper to establish than large power plants.

  • Fiscal 2019 project fostered by the Sustainable Open Innovation Initiative under the auspices of the Japanese Ministry of Economy, Trade and Industry to establish virtual power plants by using energy resources owned by electric power consumers.
