Regional Distributed Energy Supply
Contributing to Local Production and Consumption of Energy by Developing Decentralized Energy Systems
The significant changes in Japan's energy supply structure due to the expansion of renewable energy has increased the requirement for local production and consumption of renewable energy from economic rationality and regional resilience perspectives. This is driven by the decreasing costs of renewable energy generation, the constraints of existing transmission systems that cannot accommodate the variability of renewable energy, the growing awareness of disaster prevention and a circular economy at local levels. It is therefore necessary to utilize decentralized energy sources, such as local renewable energy and energy storage systems, to predict energy demand and supply and establish an optimized management system for decentralized energy. The Japanese government's’ Basic Act on Energy Policy’ also promotes the development of decentralized energy systems.
To develop a decentralized energy system, it is necessary to combine technologies related to energy supply and demand-side facilities with energy management technologies, utilizing IoT. The true value of engineering lies in nurturing, connecting and implementing elemental technologies with no specific equipment manufacturer or system vendor boundaries. The construction of decentralized energy systems can therefore be considered a field where engineering companies have a comparative advantage.
Chiyoda participates in the planning and implementation of renewable energy, and local production and consumption, from the early concept stage. We focus on developing hybrid energy supply systems that incorporate power generation, distribution, energy storage and energy sources such as hydrogen, heat and others, aiming to construct regional microgrids that respond to both normal and emergency situations and promoting the realization of clean regional cities and industries where energy and the environment are harmonized according to the characteristics of each region.
Our Regionally Distributed Energy Management Vision
Our Initiative: Constructing a Regional Microgrid
A microgrid is a form of decentralized energy system that efficiently utilizes renewable energy sources during normal conditions and, during emergencies such as large-scale disasters, operates independently from the main power grid to provide power within a specific area.
Chiyoda completed the planning and construction of a regional microgrid project in Japan in 2023, effectively utilizing renewable energy sources and enabling autonomous power supply independent of the surrounding power grid during disasters. Expectations are high for the revitalization of local industries and the use of the microgrid as a Business Continuity Plan (BCP) for the region.
Creating Decarbonized Communities
Chiyoda is participating in nationwide initiatives to resolve regional issues and achieve both regional revitalization and decarbonization. Please refer to our ‘Decarbonization Regional Development Support Site’ for further information.
Initiatives of FOURE
Chiyoda is a member of the ‘Renewable Energy Regional Activation Association,’ promoting the widespread adoption of renewable energy in local communities and fostering mutual development between regions and renewable energy.
