Solar Photovoltaic(PV)

We, Chiyoda group, are participating in, not limited to the hydro-carbon energy projects, also actively participating in renewable energy projects under the philosophy of the "Energy and Environment in Harmony".
Since the launch of feed-in tariffs (FIT) of renewable energy in Japan, 2012, we entered into the business field of large-scale solar photovoltaic (PV) plants. Then, as of the end of March 2017, we have awarded the Engineering, Procurement and Construction ("EPC") of solar PV projects with a total capacity 308 MW, 49 projects, including 6.6kV grid connection and high-voltage grid connection up to 77kV.


1. Service and feature of the Chiyoda group in large scale solar PV project

Chiyoda group provides overall project business plan, such as Feasibility Study, Applications for FIT authorization, EPC and "Operation and Maintenance (O&M)". In addition, for the acquisition of O&M service knowledge, Chiyoda is operating solar PV plants in Kyushu in collaboration with Eneseed Co., Ltd., a wholly owned subsidiary of Saibugas Co., Ltd.

2. Future development of solar PV project

We continue providing the EPC service for solar PV plants to contribute toward the Japan's renewable energy future. We will also enter into worldwide solar PV market with Chiyoda overseas subsidiaries & affiliated companies.

3. Participating in battery plant project

The demand for battery storage system has been increasing to mitigate precipitous grid fluctuation by renewable energy market growth mainly solar PV and wind. We will participate battery plant project such as ancillary service and auxiliary battery storage system of solar PV plant. We also proceed with R&D to improve system integration capability of large scale energy storage for development of peak shifting and off-grid / micro-grid system.
