UACJ Corporation (HQ: Chiyoda-ku, Tokyo; President and Representative Director: Miyuki Ishihara) announced today that its wholly owned subsidiary, UACJ (Thailand) Co., Ltd. (HQ: Rayong Province, Thailand; President: Hironori Tsuchiya), will have one of the world’s largest rooftop photovoltaic systems1 installed at its manufacturing facility, Rayong Works, based on an agreement concluded today with Kansai Energy Solutions (Thailand) Co., Ltd., a wholly owned subsidiary of Kansai Electric Power Co., Inc. (HQ: Kita-ku, Osaka; President and Representative Director: Takashi Morimoto).

Based on the agreement, Kansai Energy Solutions (Thailand) will install about 40,000 photovoltaic panels with a combined capacity of 18 megawatts on the rooftops of Rayong Works. All of the electricity generated by the system will be directly supplied to Rayong Works for consumption by its operations over a 20-year period. Through the use of this system, UACJ (Thailand) expects a reduction in CO2 emissions from Rayong Works of about 14,000 tons per year2, equivalent to approximately 6% of the facility’s annual CO2 emissions.

The UACJ Group regards efforts to combat climate change as an important task in its long-term management vision, UACJ Vision 2030. The Group plans to continue taking proactive steps towards making the world more sustainable while reducing its environmental load.

The Kansai Electric Power Group recently announced its goal to achieve carbon neutral operations by 2050, and has been actively working to reduce CO2 emissions in Japan as well as in other countries. By applying expertise and know-how gained through these efforts, it aims to help these countries become carbon neutral while providing various services tailored to the needs of consumers.

  • Notes:
  • 1. According to Kansai Electric Power’s research findings as of June 8, 2021
  • 2. Calculated using the CO2 emission coefficient adopted by the Thai government: 0.566 kilograms of CO2 per kilowatt-hour
