Contributions to the Mitigation of Climate Change by Reducing Product CO2 Emissions

Performance Data
Contributions to the Mitigation of Climate Change by Reducing Product CO2 Emissions

The Meiden Group aims to benefit the environment by using renewable energy like solar, wind and hydroelectric power and by supplying products and services that are more efficient and thus energy saving.
In fiscal 2018, we aimed to provide environmental contribution (the expected curbing effect of CO2 emissions from products sold) of about 800,000 t/year. We increased shipment of electric vehicles and transformers and high-voltage inverters for the overseas market, enabling us to achieve our target for the fiscal year, reaching emissions reductions totaling 841,000 t/year.

Performance Data

The reasoning behind calculation of environmental contributions of products and services is as follows.

Applicable products/businesses CO2reduction volume
Power conditioners for solar power generation Emissions reduction if grid power is substituted with renewable energy
Wind power sales business
Hydroelectric generators*
Electrical equipment for electric vehicles Emissions reduction if substituted for gasoline vehicles of the same grade
Power conditioners for storage batteries Emissions reduction from substitution of pumped hydroelectric generation (high efficiency)
Electrical equipment for electric forklifts Emissions reduction from the Company’s existing products (reduction in lost energy)
Engines and turbine generators
Transformers
Inverters
Uninterruptible power supplies
Total: 800,000 t

*Calculated by multiplying the difference in volume of CO2 emissions at the point of use, by the expected life and annual sales volume. However, wind power generation is calculated based on annual power generation performance.

Wind Power Generation Business

Initiatives
Wind Power Generation Business

M WINDS Co., Ltd. and its affiliates operate a wind power generation business and supply renewable energy.
M WINDS conducts electricity sales from wind power generators at three locations* in Japan (30 wind turbines with a generating capacity of 51,000 kW). It conducts environmental assessments when constructing and installing wind power generators.

*Hachiryu Wind Farm (Akita Prefecture): 18 wind turbines with a generating capacity of 28,000 kW
Wajima Community Wind Farm (Ishikawa Prefecture): 10 wind turbines with a generating capacity of 20,000 kW
Choshi Shiosai Wind Farm (Chiba Prefecture): 2 wind turbines with a generating capacity of 3,000 kW

Aiming for increased utilization of wind power

We generated 109,705 MWh of electricity in fiscal 2018, following on from fiscal 2017 when we also generated more than 100,000 MWh of power. Going forward, we aim to further improve the utilization rate in order to increase our environmental contributions.

Motors and Inverters for Electric Vehicles

Motors and Inverters for Electric Vehicles

Meidensha provided motors and inverters to be fitted to electric vehicles, which are becoming more common throughout the world. These products achieved improvements in miniaturization, lightness, efficiency, and quietness by leveraging the motor and inverter technology developed by the Meiden Group over many years.
We are currently developing drive systems for next-generation green vehicles such as inverters fitted with SiC modules.

Turbine Generators

Turbine Generators

Turbine generators are generally powered by steam or gas turbines and are widely used by industry and power companies as emergency, non-emergency, and peak-shaving power supplies.
The uptake of the four models of turbine generator produced by of Meidensha has been increasing and we have been conducting development in order to transition from cylindrical rotors to salient pole rotors since fiscal 2014, which will increase our competitiveness.
We are increasing the scope of our foundational technology such as insulation, cooling, and loss reduction, and promoting increased output in order to achieve further increases in output volume, efficiency, and lightness.

Forklift Control Devices

Forklift Control Devices

We have been supplying motors that provide the thrust for battery-powered forklifts as well as controllers for over 50 years, so that we are now an integral part of the forklift industry.
Until now, the forklift market has mainly comprised Japan, North America, and Europe; however, the recent growth of Asian countries, and China in particular, has been remarkable. Also, in the forklift industry, expectations concerning increased forklift efficiency and reduced CO2 emissions have been increasing.
In order to meet these expectations, we must secure a solid foothold for Meidensha in new markets, provide high-performance products at a low price, and contribute to the reduction of environmental impact.

Uninterruptible Power Supplies

Uninterruptible Power Supplies

The volume and importance of electronic data has been increasing in a number of areas of society, creating a need for data servers to have 24-hour stable power supply without even a moment of outage. Meidensha provides high-quality, reliable power supplies, including the highly efficient, power-saving THYRIC Series.
Meidensha has achieved a greater than 40% reduction in power loss and industry-best efficiency in the three-phase output UPS transformer 200 V class.
