Fukushima Experimental Offshore Floating Wind Farm Project
Second Phase Update

A consortium made up of Marubeni (project integrator), the University of Tokyo (technical advisor), Mitsubishi, Mitsubishi Heavy Industries, Japan Marine United, Mitsui Engineering & Shipbuilding, Nippon Steel& Sumitomo Metal Corporation, Hitachi, Furukawa Electric, Shimizu, and Mizuho Information &Research hasbeen participating in an experimental offshore floating wind farm project sponsored by the Ministry of Economy, Trade and Industry since March 2012.At present, the construction of the three-columnsemi-subas part of the second phase has been successfully completed.

1.Outline of construction works in the second phase:

Setting one 7MW oil pressure drive-type floating wind turbine and undersea cables

2.Work progress to date:

<7MW oil pressure drive-type floating wind turbine>

Floater

• Completion of construction of the three-column semi-sub floater and mooring it at Mitsubishi Heavy Industries, Ltd. Nagasaki Shipyard & Machinery Works.

Wind Turbine

• Parts procurement and construction of 7MW oil pressure drive-type floating wind turbine in progress at Mitsubishi Heavy Industries, Ltd. Yokohama Dockyard & Machinery Works.

<Undersea cables>

• Production of the undersea cable at Furukawa Electric Co., Ltd. Chiba Works.
• Preparation to connect cables to the 66kV floating power sub-stationin progress.

3.Next Step

The following activities need to be completed to start operation of the power facilities during the current year:

• * Schedule will be changed depending on the meteorological and sea conditions
