DMG MORI to launch Japan’s largest solar power system for self-use

Covering a roof area of 130,000 m2 for a capacity of 13,400 kW, it will be the most extensive solar power generation system for self-use ever built in Japan. The construction of the first batch of solar panels began in August 2022 and was completed as planned. The first batch started generating 5,400 kW of power on February 1, 2023. The current panel size will generate six million kWh per year, covering approximately 13 percent of the annual power demand at Iga Campus.

The second batch of solar panels will be completed by next year and start providing 5,200 kW (5.2 MW) from February 2024. The third batch will start operation by December 2024 to generate an additional 2,800 kW (2.8 MW) for a total of approx. 13,400 kW (13.4 MW). After the third batch, the complete solar power generation system will supply 14 million kWh (14,000 MWh) per year, which will cover approx. 30 percent of the annual power demand at Iga Campus.

The solar power generation system will be an on-site PPA*2 model provided by TESS Engineering. All generated electricity will be used for self-consumption at Iga Campus, reducing the production site’s CO2 emissions by approx. 5,300 tons per year. By installing solar power generation systems, DMG MORI can secure a stable power source for the long term to avoid market fluctuations or fuel supply problems and strengthen its business resilience and reduce CO2 emissions through renewable energy.

Carbon-neutral production

DMG MORI is making various efforts toward a carbon-neutral, recycling-oriented, and sustainable society. In the area of renewable energy, DMG MORI is already using CO₂-free electricity at all its sites in Japan and since May 2022, a newly built biomass plant is in operation at Iga Campus that utilizes wood chips as fuel for carbon-neutral power generation. Another solar power generation system has been in operation at DMG MORI’s Davis Plant in California, the U.S., since November 2022, and from February 2025, Nara Campus will also begin generating solar power.

Furthermore, DMG MORI offsets CO₂ emissions that cannot be reduced by own efforts by investing in internationally recognized sustainable climate protection projects. Since 2021, DMG MORI’s entire production – from parts procurement to product shipment – is fully carbon-neutral. Today, all DMG MORI machines worldwide are shipped with the GREENMACHINE mark.

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.
