Japan Renewable Energy Corp (JRE) announced Jan 1, 2018, that a hybrid-type power plant combining wind and solar power generation facilities has started operation in Hibiki-machi, Wakamatsu-ku, Kitakyushu City, Fukuoka Prefecture, Japan.

The total capacity of the wind and solar power generation facilities is about 9.6MW.

It is a joint project between JRE (Minato-ku, Tokyo) and Hokutaku Co Ltd (Asahikawa City, Hokkaido). The power producer of the plant, "Hibiki-nada Wind Energy Research Park," is Hibiki-nada Wind Energy Research Park LLC, which is jointly invested in by the two companies.

The project was selected as a "project for promoting the concentration of wind power generation-related industries in the Hibiki-nada District, Wakamatsu-ku, Kitakyushu City," for which Kitakyushu City called for public proposals.

The total capacity of solar panels installed at the plant is 3.046MW (10,504 panels), and the total output of the adjoining wind power generation facilities is 6.6MW (3.3MW x 2). Electricity generated at the plant is sold to Kyushu Electric Power Co Inc based on the feed-in tariff (FIT) scheme.

The plant is connected to a power grid at one connection point. Electricity generated by the solar power generation facilities is combined with electricity generated by the wind power generation facilities and transmitted to the grid.

However, the solar and wind power generation facilities were separately certified by Japan's Ministry of Economy, Trade and Industry (METI), and they transmit 2MW and 6.6MW of electricity, respectively, to the grid (8.6MW in total).

By transmitting the power generated by the wind power plant, which is not influenced by solar irradiation, and the mega (large-scale) solar power plant, which can generate electricity regardless of wind conditions, to the power grid at one connection point, it becomes possible to transmit power 24 hours a day including nighttime hours regardless of weather conditions, according to JRE.
