Using Maritime Renewable Energy Resources.
1. Revision of operational startup schedule
The Project’s commercial operation date was initially scheduled for January 2024.
However, the construction process was delayed due to defects discovered in a floatingstructure during construction. Accordingly, the Consortium filed an application to revise

TODA CORPORATION (TODA), which oversees the Project’s construction operations,announced on May 9, 2023 that defects were discovered in two floating structures underconstruction at an onshore yard. TODA subsequently confirmed the facts, investigatedthe causes and considered countermeasures. The company has also taken corrective
measures for the defects in the two floating structures and restarted construction work atthe onshore yard.
Additionally, TODA will conduct inspections of a floating structure already installed off
the coast Sakiyama to verify the existence of defects. One of the three floating structuresinstalled off the coast of Sakiyama will be landed on the yard in Fukue Port where theintegrity of the floating structure will be verified. Based on the results, TODA plans todecide whether to inspect the remaining two floating structures.
