Commencement of Construction for Narita International Airport's New Central Power Substation

Narita International Airport Corporation (President: Naoki Fujii, hereinafter "NAA") and Tokyo Gas Co., Ltd. (President: Shinichi Sasayama, hereinafter "Tokyo Gas") have established Green Energy Frontier Co., Ltd. (President: Tadayoshi Nishimoto, hereinafter "GEF"). GEF will commence construction of the new Central Power Substation on April 1st, marking the first full-scale renewal of the Central Power Substation, which has supported power distribution within Narita Airport for approximately half a century since its opening.

The Central Power Substation is planned to increase its power reception capacity by approximately 1.5 times compared to the current Central Power Substation, with completion scheduled for fiscal year 2028. This will enable the airport to cope with the future increase in electricity demand due to the "Narita Airport Second Opening Project," which includes NAA's ongoing runway expansion, passenger terminal building reconstruction, and new cargo area development.

The construction of the Central Power Substation is the first phase of GEF's large-scale energy infrastructure renewal project within Narita Airport. In the future, a second phase involving the renewal of the heat supply plant will also be considered.

Through the construction of the Central Power Substation, GEF, NAA, and Tokyo Gas will contribute to building a resilient and advanced energy infrastructure that supports the sustainable development of Narita Airport, a leading international hub airport in Japan.

■ Features of Central Power Substation

① Seamless Equipment Renewal and Scalability for Decarbonization

The design ensures a seamless transition from the current Central Power Substation to the Central Power Substation without power outages. Furthermore, the equipment configuration is designed with future introduction of decarbonization facilities, such as solar power generation, in mind.

② Introduction of an AI-Powered Energy Demand Forecasting System

The Central Power Substation is planned to implement an AI-powered energy demand forecasting system in collaboration with Tokyo Gas's Next-Generation Technology Research Laboratory and NAA. In the future, it is envisioned to link with a database planned by NAA, utilizing airport data such as flight schedules, weather information, and various operational data to achieve more precise demand forecasting. Based on this, the aim is to optimize operations, including heat supply facilities.

③ Integration of GEF Headquarters

GEF's headquarters, currently located outside the airport, will be relocated within the Central Power Substation. This aims to improve crisis response capabilities for energy supply by facilitating information sharing and speeding up decision-making during emergencies.
