Newly Established Green Energy Frontier Co., Ltd. to Begin Operation- Energy Supplier will Contribute to Decarbonization Drive atNarita International Airport Narita International Airport CorporationTokyo Gas Co., Ltd.
Narita International Airport Corporation (NAA) (President & CEO: Mr. Akihiko Tamura)and Tokyo Gas Co., Ltd. (Tokyo Gas) (Representative Corporate Executive Officer,President and CEO: Mr. Takashi Uchida) have established Green Energy Frontier Co., Ltd.
to supply Narita International Airport with its energy requirements. The new company
will begin operating on April 1, 2023.
NAA will transfer*1 its energy supply facilities to Green Energy Frontier on April 1 sothat the new company can begin supplying Narita International Airport with energy forelectricity and heating, and take on the challenge of decarbonizing the airport's energy
supplies by 2050. Between then and 2050, the new company will invest 100 billion yen
in the construction of new energy plants and the installation of the largest airport solarpower generation plant in the world*2, with an output of 180 megawatts*3.

Logo① Supply of energy to ensure stable electricity
and energy supply② Airport decarbonization

Narita International Airport is Japan's primary air transport gateway and isundertaking a major capacity enhancement project to accommodate a global surge indemand for air transport and increases in passenger traffic from neighboring countries

in Asia, as well as to meet competition from around the world. It has also declared acommitment to zero carbon emissions from airport facility energy supplies and airport
service vehicles by 2050.
Green Energy Frontier will take over NAA's energy supply facilities, including its extra
high-voltage substations and heat source facilities, and will devote its efforts to energy
supply and airport decarbonization by utilizing the Tokyo Gas Group's expertise inbuilding and operating large-scale energy plants, large-scale solar power projects anddecarbonization technologies such as e-methane*4.
Moving Toward Decarbonization of Narita International Airport
Green Energy Frontier will take up the challenge of decarbonized energy supplies forthe airport in 2050. During that transition period, the company will work toward
improving energy efficiency and steadily reducing carbon emissions by introducing
more advanced management of existing plants and building new plants. It then has
plans for a large-scale solar power generation plant and the introduction of next
generation decarbonization technology, including hydrogen and carbon recycling, witha total investment of 100 billion yen by 2050. It will be the first in the world to createa "decarbonization model for airports" at Narita International Airport by combining
environmental friendliness with resilience, and will adapt this technology and expertise
into urban development and industrial parks around the airport.

Specific Initiatives① Replace existing plants with cutting-edge energy plants
・ Phased replacement of aging central power distribution plant and central heating
and cooling plant with new energy plants(Expected completion: First half of 2027 for the new central power distribution plant,and first half of 2034 for the new central heating and cooling plant)
・ Overall reduction in carbon emissions and enhancement of resilience through theintroduction of a cutting-edge energy management systems as well as advanced
technology in the form of digital innovation in security, etc.

・ 75 MW by the end of fiscal 2030 and a further 105 MW by the end of fiscal 2045
・ Use of locally produced and consumed energy to decarbonize electricity for about
70,000 households*5

■ Comment by Mr. Akihiko Tamura, President and CEO, Narita International
Airport Corporation
Replacing aging energy supply facilities and reducing our environmental impact in
the future through decarbonization are major challenges at Narita International Airport
at present. In order to address these challenges, we felt that the shortest and mosteffective path was a joint venture with Tokyo Gas because of its wealth of knowledgeand experience in the energy supply business, and the advanced decarbonization
technology it possesses. To that end, we formed the joint venture company, GreenEnergy Frontier. We will now confront these challenges together with Tokyo Gas andwork toward stable energy supplies and decarbonization at Narita International Airport.
■ Comment by Mr. Takashi Uchida, Representative Corporate Executive
Officer, President and CEO, Tokyo Gas Co., Ltd.
The joint venture between Narita International Airport and Tokyo Gas has a major
mission built on a history of 40 years of supplying energy to the airport: the 2050decarbonization of energy supplies. Based on the knowledge and technologicalcapabilities we have acquired to date, we will introduce the latest digital innovations
and development technologies of the day and form alliances with other companies toaddress the challenge of responsible transition. Narita International Airport is a key
element in Japan's infrastructure and it is where we will provide stable supplies,advanced resilience, improved productivity and advanced decarbonization for thefuture of the airport and the future of the world.

Existing main gas infrastructure and appliances can be used, thus enabling a smooth transition to carbon
neutrality while also curbing the cost to the community.
