UACJ (Thailand) Co., Ltd., a subsidiary of UACJ Corporation, signed an agreement with Kansai Energy Solutions (Thailand) Co., Ltd. to construct one of the one of the world’s largest rooftop photovoltaic systems. The solar power system will be installed on the Rayong Works, an aluminum rolling and manufacturing facility in Thailand.
Established in February 2010, UACJ (Thailand) manufactures and sells flat rolled aluminum for can stock, automotive heat exchangers, electrical and electronic components, and other industries.
Based on the agreement, Kansai Energy Solutions (Thailand) will install about 40,000 photovoltaic panels with a combined capacity of 18 MW on the rooftops of Rayong Works, covering approximately 87,000 sq m. The system will produce around 25,000 MWh per year. All of the electricity generated by the system over a 20-year period will be consumed by UACJ (Thailand).
Through the use of this system, the aluminum producer expects to reduce CO2 emissions from Rayong Works by 14,000 tons per year (calculated using the CO2 emission coefficient adopted by the Thai government or (0.566 kg of CO2 per kWh). This is equivalent to approximately 6% of the facility’s annual CO2 emissions. The group plans to continue taking proactive steps towards reducing its environmental load to help make the world more sustainable.
