Introduction

Tokyo Gas Engineering Solutions (TGES), under the leadership of President Takayuki Kaminaka, has launched an innovative initiative known as the Yaesu and Nihonbashi Smart Energy Network project. This significant endeavor corresponds with the completion of the TOFROM YAESU TOWER, where a new district heating and cooling plant (the 'New Plant') has been established underground. This project links the New Plant with the existing district heating and cooling facility (the 'Existing Plant') to create an optimized smart energy network ('SmaEne'). As a result, the project is expected to enhance heat production efficiency by approximately 15% compared to the pre-project scenario. This initiative serves as a model case for enhancing value not just in the redevelopment area but across the existing district cooling zones.

Key Features of the Project

1. Synergistic Operation of New and Existing Plants

By connecting the New Plant, built in conjunction with the redevelopment, to the Existing Plant, TGES can make effective use of advanced heating systems, such as the highly efficient turbo refrigerants installed in the New Plant. The project integrates a newly established gas cogeneration system (CGS) within the redevelopment structure to ensure that waste heat generated during power production is utilized efficiently. This collaboration is projected to improve heat production efficiency by approximately 15%. The selected CGS is equipped with a blackout start feature, ensuring reliable power supply during outages and maintaining heat delivery from the New Plant. Furthermore, the interlinked operation of both plants enhances the stability of the entire district's heat supply, providing essential backup should either of the systems experience downtime.

2. Efficient Operations through AI and Remote Monitoring

TGES employs artificial intelligence to predict heat load based on weather data and operational records, facilitating optimal machine operation through the newly introduced Smart Energy Network Energy Management System (SENEMS). Utilizing Tokyo Gas's control and monitoring solution, JoyWatcherSuite, the company is developing a system for remote monitoring and inspection, ensuring operational efficiency is maximized through the integration of digital technologies and data utilization.

3. Future-Linked Redevelopment for Enhanced Community Value

In the vicinity of this project, new redevelopment efforts are underway. These developments will incorporate interconnected district heating and cooling systems, aiming for a future wherein three plants operate cohesively. This strategy is designed to further improve energy efficiency across the supply area and forge a robust, reliable energy distribution framework, significantly enhancing the community's overall value.
