District Heating and Cooling Services


District Heating and Cooling Services

The Tokyo Gas Group operates district heating and cooling services, including small-scale heat supply, in 54 districts. We supply steam and hot and cold water with combined heat and power (CHP) systems* that use natural gas, absorption chillers and boilers. We work on fine-tuning the machines to increase energy efficiency and improve their operational efficiency as well.
*Gas engine-based CHP systems generate electricity and recover waste heat generated as a by-product.

Makuhari District Heating and Cooling Center

We have updated heat source equipment at the Makuhari District Heating and Cooling Center and converted it into a regional energy center for power generation and heat supply that promotes region-wide reductions of energy use and CO2 emissions, from a conventional district heating and cooling center that supplied only heat. We have optimally mixed the use of the latest highly efficient large-scale CHP system with a total capacity of 15.7 MW, an electric turbo chiller, a boiler and an absorption chiller while also reducing fuel consumption by 19% and CO2 emissions by 19% (fiscal 2015).
