The Numazu Works is the main factory of the Meiden Group and conducts development, design, and manufacture of supervisory control equipment, power conversion equipment, power transformers and distribution panels , motor control equipment(inverters), electronic products, and surge arresters, development of software for integrated control devices and standalone, and on-site installation, and after-sales service for products.

At Numazu Works, we are promoting efficient energy use through capital investment and reform of equipment operation and are advancing replacement of SF6 gas with dry compressed air, as a measure to reduce emissions of SF6 gas, which is a particularly potent greenhouse gas, in the product testing process.

Additionally, to comply with the purposes of the Building Standards Act (one water-purification tank per site) and the Private Sewerage System Act (obligation to make efforts to convert individual water-purification tanks to combination water-purification tanks), and to avoid the risk of process wastewater spills, a complete upgrade on the wastewater system at the plant began in FY2022. By consolidating 28 existing tanks (22 individual water-purification tanks and six combination water-purification tanks) into one combination water-purification tank to be newly constructed, and rerouting the process piping, we will achieve safe water treatment and reduce electricity consumption with the improved operating efficiency of the treatment facilities.

The Ota Works conducts development and manufacture of large electric generators, power generation equipment, dynamometer systems, and control equipment, etc.

In addition to previous environmental activities, this year, we sourced CO2-free electricity that is produced and consumed within Gunma Prefecture and achieved zero greenhouse gas emissions from electricity consumption. We will continue working to reduce our environmental impact and achieve the SDGs.

The Nagoya Works develops and manufactures logistics and transportation products and ceramic membranes used for water treatment and has manufactured integrated motor and inverter units for EVs since FY2020.

In FY2022, our factory for integrated motor and inverter units for EVs went into full operation, plus production of ceramic membranes increased, resulting in higher emissions of greenhouse gases. However, we worked to achieve efficient equipment operation, and emissions per unit of production were improved. As the rate of decarbonization is increasing and technology for electrification, computerization, and artificial intelligence of electric vehicles is evolving rapidly, Nagoya Works is focusing on electrification and will continue to contribute to society through future automation of automobiles.

Since its foundation in 1943,　KOFU MEIDENSHA ELECTRIC MFG. CO., LTD. has been manufacturing small and medium-capacity industrial motors and forklift motors, and has been manufacturing EV motors since 2009.

In FY2022, our new factory for EV motors went into full operation, resulting in greater energy use. However, we worked to achieve efficient equipment operation, and emissions per unit of production were improved. In addition, since FY2022, we have been sourcing renewable electricity for a portion of the electricity we use as we work to reduce greenhouse gas emissions.
