DMG MORI CO., LTD. (hereinafter referred to as “DMG MORI”) is committed to promoting a sustainable society with the installation of photovoltaic power generation systems at our locations worldwide. After the stepwise ramp-up at Iga Campus, Nara Campus has now added its own power generation as we celebrate the new opening of the world’s largest automation system solution plant.

In August 2022, DMG MORI began the three-phase installation of solar panels on the rooftops of Iga Campus (Mie, Japan), our largest production base. In February 2025, the full system started operation across 130,000 m² with a capacity of approx. 13,400 kW. This makes it Japan's largest*1 solar power generation system for self-use with an annual generation of 14 million kWh, covering approx. 30% of Iga Campus’ annual electricity needs and reducing CO2 emissions by approx. 6,000 tons per year (equivalent to the annual CO2 absorption of about 200,000 camphor trees*2).

In April 2025, Nara Campus (Nara, Japan) will near the end of its renovation and open as one of the world's largest automation system solution plants. With the same solar power system by on-site PPA*3 provided by Tess Engineering Corporation (Yodogawa-ku, Osaka) as in Iga, Nara Campus started power generation in November 2024 across 29,000 m² with a capacity of approx. 3,000 kW to generate 3 million kWh per year and cover approx. 30% of Nara Campus’ annual electricity needs, reducing CO2 emissions by approx. 1,300 tons per year (equivalent to the annual CO2 absorption of about 43,300 camphor trees*2).

DMG MORI is committed to securing power sources that remain stable over the long term and are unaffected by fluctuations in power demand or fuel shortage to ensure the continuity of our business and reduce CO2 emissions through renewable energy. Therefore, we are expanding the installation of solar power generation systems within the Group. In 2026, we will start solar power generation at a new factory building for Magnescale in Nara followed by Nagaoka, Niigata Prefecture, in 2027.

In addition, DMG MORI will install batteries for storing excess solar power generated on the weekend at Iga Campus (total: 1,000 kWh) and Nara Campus (total: 600 kWh). In the event of a disaster power outage, the batteries serve as a power source for air conditioning and lighting in critical offices, as well as for servers, etc., to enable approx. 10 hours of initial response. Furthermore, Iga Campus will utilize its existing in-house power generation facility as a backup power source and operate in hybrid mode with its solar power generation system, thus being able to supply the power needed for 3 days of plant operation with approx. 70% of the normal power load and continue plant operation. In addition, four EVs and PHEVs have been installed at Iga Campus from June 2024 to be dispatched to nearby evacuation centers to supply power in the event of a disaster power outage. From April 2025, we will start the installation of 15 EV chargers to encourage our employees to invest in EVs for commuting to work.

DMG MORI will continue to expand the use of renewable energy to accelerate the reduction of CO2 emissions and contribute to the realization of a carbon-neutral society.

*1 Information on self-use solar power generation with on-site PPAs was researched by DMG MORI from publicly available sources.

*2 CO2 absorption per Camphor tree (80 years old, 30 m high) is calculated as 30 kg-CO2/year.

*3 PPA: Abbreviation for Power Purchase Agreement. A form of contract in which electricity consumers purchase renewable energy power directly from power generators. The on-site PPA model is a business model in which a power generation facility is installed on a customer's premises or roof, and the power generated there is sold to the customer.
