DHC & Smart Energy Network

Evolving District Heating and Cooling Solutions to Smart Energy Networks, We Effectively Utilize Energy and Contribute to an Environmentally Friendly Society.


Tokyo Gas Engineering Solutions (TGES) is Japan's largest operator of district heating and cooling (DHC) facilities, providing steam, chilled and hot water for more than 40 years to our customers.
Now, we are taking the DHC business to the advanced level, creating Smart Energy Networks (SEN) by connecting multiple DHC plants. TGES aims to further contribute to reducing the carbon footprint and environmental impact of urban development.

Advantages


Advantage 1 Effective utilization of unused and renewable energy
By constructing a network for heat, electricity, and information and implementing a high-efficiency combined heat and power system, we contribute to stabilizing fluctuations in renewable energy.

Advantage 2 Contributing to regional BCP (Business Continuity Plan) enhancement
Distributed energy systems like combined heat and power systems and DHC can meet customers' demands even in the event of grid power outage, contributing to regional energy security.

Advantage 3 Reducing the carbon footprint through optimal control of regional supply and demand
By using information and communications technologies (ICT), managing and controlling supply & demand, and visually presenting energy conditions, we can realize an optimal energy balance and create a low carbon community.

Our 40 Years of Experience on DHC & Smart Energy Network


Japan's first DHC using natural gas began operation in Shinjuku central area, Tokyo in 1971. Since then, TGES and Tokyo Gas group has contributed to its further development of DHC for over 40 years. Currently, there are 133 DHC centers in Japan and TGES currently owns 15 centers which is approximately 10% of them. Tokyo Gas group are related to more than 100 heat supply Plants.
