[Reference] Characteristics of offshore wind power generation and superiority of port space

○ Offshore wind power generation has advantages such as better wind conditions and higher equipment utilization rates than on land.

Ports and harbors are considered promising as a suitable site for the introduction of the facility due to the factors set out below.

① As a port and harbor is a site where many industries are located by utilizing the "location characteristics of the maritime and land boundaries" and therefor the high demand for electric power is expected, its electric facilities such as transmission lines are readily available.

② Port infrastructure used for construction and maintenance of offshore wind power generation facilities is in close proximity to offshore wind power generation facilities.

③ With the existence of a Port Administrator as defined in the Port and Harbor Act, and certain procedures concerning the building of consensus among the parties concerned and the permission for occupancy, ports and harbors can be said to be the most developed site in terms of the management of the sea area and the coordination of the use of the sea area.

Outline of the Auctioned Occupancy System in respect of Offshore Wind Power Generation at Ports and Harbors (Revised Port and Harbor Act enacted in July 2016)

<Background of introduction of offshore wind power

generation facilities at ports and harbors>

・ Huge space and stable wind energy・ Easy transport of parts and equipment by sea transport・ Close to the hinterland and easy to connect to the power system

● Facilitation of introduction of offshore wind power generation facilities at ports and harbors

It is necessary to clarify the criteria and procedures for properly selecting occupants for long-term occupancy permit, while taking into consideration the maintenance and management of facilities, etc.

● Establishment of Procedures for Occupancy Permission by Auction・ Establishment of procedures for the establishment of facilities (offshore wind power generation facilities, etc.) that occupy

water areas, etc. in port and harbour areas for a long period of time.

① Port Administrator establishes a guideline for auctioned occupancy

② Business operator submits an action plan concerning their intended use of maritime areas to Port Administrator

③ Port Administrator shall select the person who submits the most appropriate plan and certify the plan (the validity period of the certification shall be 20 years or less).

④ Business operator applies for occupancy permission based on the accredited plan.

Port Administrator grants occupancy permission.

Initiatives for the introduction of offshore wind power generation at the Port of Kitakyushu

○ Kitakyushu City applied for the first time in Japan the Auctioned Occupancy System established under the Revised Port andHarbor Act enacted in July 2016, and launched in August 2016 the auction for the Offshore Wind Power Generators(prospective occupants) at Kitakyushu Port.

○ Kitakyushu City established the Business Operator Evaluation and Selection Committee for the Establishment and Operationof Hibiki Offshore Wind Power Generation Facilities, which consists of outside experts. In February 2017, Kitakyushu Cityselected Hibiki Wind Energy as a prospective occupant based on the results of the review and evaluation by the Committee.

⇒Introduction of examination concerning Port L2

Seismic Motions

○ When offshore wind power generation facilities are installed in port areas, an examination by the Port Administrator regarding the construction of offshore wind power generation facilities is required throughthe procedures for the occupation of water area in accordance with the Port and Harbor Act.

○ The construction of offshore wind power generation facilities is a private business, however the facilities will be constructed on a publicly owned water surface and in the water areas, etc. where ships sail.Therefore it is necessary for the Port Administrator who manages the water areas to check and confirm that the construction will be carried out safely, smoothly, and reliably, and that the water areas and portscan be used without disruptions.
