The Tokyo Electric Power Company, Inc. (TEPCO) will launch the "Experimental Study on
Offshore Wind Power Generation Systems" (hereinafter "the Study") in June this year.
As a joint research project with the New Energy and Industrial Technology Development
Organization (NEDO), the Study aims to establish methods for operating and maintaining
offshore wind turbines and formulate design guidelines for wind power generation
systems by setting up a fixed-type offshore wind power generation facility about 3 km
off the southern coast of Choshi, Chiba.
Prior to the Study, TEPCO started the "Experimental Study on Offshore Wind Observation
Systems" in August 2009 in coordination with the University of Tokyo as a project
entrusted by NEDO. The aim of this project is to monitor meteorological and hydrographic
conditions, including wind and wave conditions, by building an offshore wind observation
tower in the target sea area.
The Study is an extension of this earlier project and will be a next step toward the
commercialization of offshore wind power generation. In the Study, a fixed-type offshore
wind power generation facility running a wind turbine equipped with a 90-meter diameter
rotor will be operated from June 2010 (slated) to March 2014 in the target sea area.
Its objective is to establish methods for designing, installing, operating and
maintaining wind power generation systems in the hostile natural environment in the
seas near Japan, and to identify the environmental effects of offshore wind power
The outcome of the Study, along with that of past studies, is expected to be used by
NEDO for achieving its goal of establishing offshore wind power generation technologies
suited to the natural environment of Japan.
As part of efforts to increase the use of renewable energy, TEPCO will remain committed
to studies to develop safe and cost-effective offshore wind power generation systems to
make use of wind energy on the sea, where wind conditions are better than on shore.
