The Agency for Natural Resources and Energy, the Ministry of Economy, Trade and Industry (METI), discussed the draft environmental impact statement of a wind power generation project that Toyota Motor Corp is planning on the premises of "Toyota Motor Tahara Plant" in Tahara City, Aichi Prefecture, Japan, at a meeting of the Wind Power Subcommittee of the Advisory Committee on Environmental Reviews May 15, 2019.
According to Toyota, which participated in the meeting, the company will install six large-scale wind power generation systems (rated output: 4.3MW each) with a total output of 25.8MW. Electricity generated with the systems will be consumed in the plant without using the feed-in tariff (FIT) scheme.
The reclamation and foundation work for the project will start in August 2019. The systems are scheduled to start trial operation in July 2020 and normal operation in March 2021.
Toyota announced the "Factory CO2 Zero Challenge," which is part of "Toyota Environmental Challenges 2050," in October 2015 and aims to achieve zero CO2 emissions at its manufacturing plants in the world in 2050. Specifically, the company plans to (1) develop and introduce low-CO2 production technologies and thoroughly reduce CO2 emissions through daily Kaizen (improvement) activities and (2) utilize renewable energy and hydrogen energy.
The large-scale wind power generation facilities of Tahara Plant is part of such efforts. And electricity generated with the facilities will be used for production at the plant.
The wind turbine employed for the facilities has blades with a rotation diameter of 120m, and the highest point of the blades reaches 145m from the ground.
In the phase of the Environmental Assessment Procedure, Toyota announced five plans for the project including a plan to install 12 2.1MW turbines. However, by employing a plan to install a small number of large-scale turbines, the company kept large distances to existing facilities and residences in consideration of safety and reduced the number of turbines in a southern area with consideration for birds.
Toyota Motor Tahara Plant is located in one of the areas having the best wind conditions in Japan. In the area, there are 20 wind turbines in operation. They include the wind turbines of Japan's largest hybrid-type power plant consisting of a 50MW solar power plant and a 6MW wind power generation system (three 2MW wind turbines). The hybrid plant was built by Mitsui Chemicals Inc, etc (Panels of 4 Manufacturers Used at Solar/wind Hybrid Power Plant).
