Benefits of power plants with 1-year operation record

EnBio HD has developed and operated solar power plants in Japan by itself or through joint ventures with other companies (2MW Rooftop Solar Plant Adopts Panasonic 'HIT' Heterojunction Panels). Amid such circumstances, the company began to find it attractive to acquire solar power plants in operation after selling power for about one year. It was also beneficial to efficiently develop and operate solar power plants with a total output of 30MW, which EnBio HD aimed for in its mid-term business plan.

EnBio HD limited its target projects for acquisition to those in operation for about one year and that have a positive track record. Projects before starting operation have such risks as the lack of important requirements to meet during development.

Original developer Next Energy approached EnBio HD about taking over its projects in Chino City and Ina City almost one year after the plants had begun operation. As the plants had been operating just as long as EnBio HD was seeking, the companies reached an agreement, and both plants were transferred to EnBio HD.

According to EnBio HD, it had the sense of security in and trusted Next Energy through joint solar power plant developments. That also led to the acquisition of those power plants.

EnBio HD jointly developed with Next Energy mega-solar plants with a solar panel capacity of 2.3738MW in Kume-gun, Okayama Prefecture, and about 1.95MW in Urahorocho, Hokkaido. They began operation in September 2015 and February 2017, respectively (1.9MW Solar Plant in Hokkaido Generates Most Power in Winter).

EnBio HD also took over both of these power plants and became their sole owner by purchasing Next Energy's stakes after their operation began.

At the power plant in Urahorocho, Hokkaido, generated power is sold at 36 yen/kWh while solar panels manufactured by Upsolar Group Co Ltd of China and Wave Energy (Minato-ku, Tokyo) Inc's all-in-one product, which primarily integrates PV inverters and other related devices of Toshiba Mitsubishi-Electric Industrial Systems Corp (TMEIC), were adopted. The all-in-one product integrates current collectors, PV inverters, step-up transformers and other devices.

At the power plants in Chino City and Ina City, generated power is sold at 36 yen/kWh and 32 yen/kWh, while PV inverters manufactured by SMA Solar Technology AG of Germany and Wave Energy's all-in-one product, the same as the one used in Urahorocho, were adopted, respectively. Next Energy's solar panels (Fig. 4) are used at both plants.
