Consortium Formed for Offshore Wind Power Project
Near Noshiro, Mitane and Oga in Akita Prefecture
Sumitomo Corporation (Head Office: Chiyoda-ku, Tokyo; Representative Director, President and Chief
Executive Officer: Masayuki Hyodo), INPEX Corporation (hereinafter, “INPEX”), Japan Petroleum
Exploration Co., Ltd. (hereinafter, “JAPEX”), JR-EAST Energy Development Co., Ltd. (hereinafter, “JED”),
Kato Construction Co., Ltd. (hereinafter, “Kato Construction”), Narita Construction Co., Ltd. (hereinafter,“Narita Construction”), TEPCO Renewable Power, Inc. (hereinafter, “TEPCO RP”) and Venti Japan Inc.
(hereinafter, “Venti”) have formed a consortium (hereinafter, “the Consortium”) to take on an offshore wind
power project (hereinafter, “the Project”) near the cities of Noshiro, Mitane and Oga in Akita Prefecture(hereinafter, “the Sea Area”) for which a public tender is scheduled.

The national government’s Basic Energy Plan sets out an objective for 2030 of achieving a power
generation mix in which 22%-24% of power is provided through renewable energies, making theconsideration/planning of offshore wind power generation, a power source with enormous potential, anurgent issue. In accordance with the “Offshore Renewable Energy Act” (Note), the national governmentis presently designating areas (promotion areas) for which offshore wind power producers will be selectedby public tender. The Sea Area offers a very suitable natural environment, with its favorable windconditions and relatively shallow waters, so it appears likely to be designated a promotion area.

In working toward the commercialization of offshore wind power generation in the Sea Area via the Project,
Sumitomo Corporation has since 2018 been conducting environmental impact assessments, seabedsurveys, wind condition studies and other research with the understanding of local governments and thecooperation of local fishermen. The Consortium as the operating body will be making preparations for
submitting a proposal for proprietary use and taking full advantage of the knowledge and know-how of its

member companies to step up the process toward commercialization. More specifically, Sumitomo
Corporation, which has a long track record of developing/operating wind power stations both inside andoutside Japan, Venti, Kato Construction, JED and Narita Construction, which are all locally engaged in
the wind power generation business in Akita Prefecture, TEPCO RP, which has considerable experienceand achievements in validating and operating the Choshi Offshore Wind Farm, Japan’s largest offshore
wind farm, and which has heretofore demonstrated a full range of technical capabilities in planning,building, operating and maintaining hydroelectric power stations and other power plants, and INPEX andJAPEX, which have long been an integral part of the local petroleum and natural gas scene in Akita
Prefecture, will be coordinating on these preparations.

The Consortium will bear in mind the views expressed by a council comprising representatives from
Noshiro, Mitane and Oga as well as the national government’s policies as it endeavors to ensure reliable,
efficient and long-term power generation in the Sea Area that will help bring about a clean and sustainabledecarbonized society and boost growth in local communities.

Generation Facilities Using Maritime Renewable Energy Resources
