Nikken Kosakusho Works, Ltd. ( “Nikken” or “the Company” ) announces its decision to
introduce a large-scale (capacity greater than 1 MW) in-house solar power generation facility on
the 55,000-m2 property of its head office and factory in the city of Daito, Osaka, in a joint projectwith Kansai Electric Power Co., Inc. ( “Kansai Electric Power” ) aiming to promote efforts toreduce greenhouse gas emissions toward the realization of a decarbonized society.

Overview of new facility■ Solar panel capacity: 1.920MW (1,920kW9)■ Annual in-house consumption: 1,972MWh (1,972,000kWh)■ Annual CO2 emissions reduction: About 20%

Background
In October 2020, the Japanese government pledged to achieve carbon neutrality by 2050 as ameasure to combat climate change. In addition, in April 2021, the government published a newgreenhouse gas emissions reduction target of 46% from fiscal 2013 to fiscal 2030.
Nikken’ s introduction of an in-house solar power generation facility should substantially reduce its
CO2 emissions and enable the Company to reduce its burden on the environment.
■ Construction start date

: October 9, 2021

■ Scheduled completion: Mid-January 2022

By consuming power generated on-site, Nikken expects to cut its annual CO2 emissions by about 20%.
Facility construction began on October 9, 2021, and is scheduled for completion in mid-January 2022.
Overview of joint project with Kansai Electric Power
Kansai Electric Power will install solar power generation equipment on the rooftops of the twomain factory buildings on the property of Nikken’ s head office and factory, and will operate andmaintain the equipment as their own thereafter as part of the on-site solar power generation service
they provide to businesses around Japan. The solar panel capacity will be 1.92 MW, and theestimated annual power output is 1,972 MWh, making this facility the largest among those
provided in Japan by Kansai Electric Power under the service.
BCP measures: Overview of electricity storage equipment
Severe natural disasters have occurred frequently in recent years due to factors such as globalwarming. Many long-lasting power outages have also occurred, and companies are realizing theindispensability of BCP measures. The solar power generation facility to be installed at Nikken will
be equipped with storage batteries with capacity of 153.6 kWh for supplying a finite amount ofelectricity during power outages.
*Region’ s largest
Nikken’ s head office and factory are located in an urbanization promotion area within a 2-km
radius of the Daito City Office in Osaka Prefecture; with a power generation capacity of 1.92 MW,
the new facility will be the largest in the city. In the former Kitakawachi region, which includes thecities of Moriguchi, Hirakata, Neyagawa, Kadoma, Shijonawate, and Katano, the facility’ s
capacity will be on par with the 1.5-MW maximum capacity of the solar power plant at Nagisa
Mizu Mirai Center operated by the Osaka prefectural government.
