Energy Storage

Promoting Battery Energy Storage Systems

Renewable energy faces the challenge of fluctuating solar and wind power generation due to the weather conditions and unstable outputs. Therefore, battery energy storage systems resolve by alining power supply and demand to stabiize grid output, thereby facilitating the future expansion of these key power generation sectors towards the widspread adoption of renewable energy,

Chiyoda contiunes to contribute towards carbon neutrality through the engineeering, procurement and construction (EPC) of battery energy storage facilites (since 2018), as well as in the maintenance and support of stable operations for these facilities.

In March 2023, Chiyoda completed the EPC for the world's largest battery energy storage system for North Toyotomi Electric Power substation, supporting the extensive use of wind energy in Hokkaido, as part of a "Demonstration Project for Transmission Network Development for Wind Power Generation" undertaken by North Hokkaido Wind Energy Transmission Corporation. The facility is crucial in mitigating wind turbine power output fluctuations caused by chainging weather patterns, and contributes to the stabilization of the power grid and the expansion of wind power generation in the northern region of Hokkaido, Chiyoda is further supporting the customer through the execution of a twenty(20) years facility maintenace work order.

Competition in the renewable energy industry is expanding following its transition from the Feed-in Tariff(FIT) system to the Feed-in Premium(FIP) system. Chiyoda has completed demonstartions as listed below to increase power sales and enhance energy resilience and, by applying its renewable energy management expertive and technological process accrued from the successful delivery of energy management facilites, supports using battery energy storage systems in conjunction with renewable energy power plant to add customer value.

We are currently engaged in multiple grid-scale battery energy storage system EPC projects. Our group are proposing design with the characteristcs of lithium-ion batteries as hazardous materials with cost competitiveness.
