The Tokyo Metropolitan Government is working to implement advanced energy management measures to maximize energy efficiency in order to achieve “Zero Emission Tokyo.”
As renewable energy becomes the mainstream, adjustment capabilities such as demand response (DR) ^{[Note 1]} are becoming increasingly important. As a result, the Tokyo Metropolitan Government will renew its existing businesses ^{[Note 2]} to further optimize electricity supply and demand, and will begin providing support for the introduction of equipment necessary for energy management systems (EMS) ^{[Note 3]} and aggregation businesses (ERAB) ^{[Note 4]} from fiscal year 2025.

[Note 1] To increase or decrease power consumption depending on the operation status of renewable energy sources in order to stabilize the power supply grid.
[Note 2] The following two projects will end in FY2024 (new applications are no longer accepted)
“Project to promote energy management using thermal storage tanks, etc.” and “Project to support aggregation businesses using distributed energy resources such as storage batteries.”
[Note 3] An energy management system required to visualize energy usage and achieve energy conservation through remote and automatic control.
[Note 4] A business that bundles energy resources such as renewable energy and storage batteries, and adjusts the supply and demand of electricity in the market or among multiple consumers using DR and other methods.
