Some 900,000 solar panels have been installed on a former salt field site in Setouchi City. The power plant is a clean source of energy for about 80,000 homes. A new seawall was built as part of the project and provides additional flood protection for the local community, while the existing habitats for rare birds, including the Eastern marsh harrier and the Black-faced spoonbill, were carefully preserved. We were owner’s engineer for Setouchi Future Creations LLC, assessing energy yield, drafting plant test procedures, supporting contract negotiations and advising on procurement.
We introduced a new way of improving the accuracy of weather forecasts and got the backing from investors for our approach. This involved using data from the local weather station to correct satellite information to estimate long-term irradiance. After financial close, we provided site construction management services. Commercial operation started in October 2018 and the city is receiving income through land-lease arrangement with the solar plant’s owner.
