In order to realize “Zero Emission Tokyo,” the Tokyo Metropolitan Government is strengthening its efforts to make effective use of energy, including supporting the implementation of energy management that optimizes supply and demand.
We are pleased to announce that we have established a new subsidy program to support the introduction of cogeneration systems (CGS), which are expected to be used as an effective balancing force as the introduction of renewable energy continues to expand, and that we will begin accepting applications for fiscal year 2025.
