Initial situation and requirements

The Kushiro and Tokachi districts in Hokkaido, where JAG Energy Co., Ltd is completing the power plants construction phase, have a relatively large number of sunshine hours making up one of the lowest snowfall areas in Hokkaido. Based on its extensive experience and technical expertise in the inspection of PV power plants both globally and in Japan, TÜV Rheinland was selected by Shinsei Bank to carry out an independent technical evaluation of the project as a third-party certification and inspection organization.

About Shinsei Bank Ltd., JAG Energy Co. Ltd. and TÜV Rheinland

About Shinsei Bank, Ltd.:

Shinsei Bank established its Project Finance Department in June 2012 to strengthen its business framework, primarily focusing on the Clean Energy industry to include solar power generation as one of its strategic areas for new business opportunities. In order to alleviate the stress placed on the electricity supply caused by the Great East Japan Earthquake, Shinsei is actively engaged in financing projects within this industry.

About JAG Energy Co., Ltd.:

JAG Energy Co., Ltd., a company under the umbrella of the Japan Asia Group Limited, has erected solar power plants on vacant land across Japan. The Group’s portfolio of 24 solar power plants in four European countries demonstrates its history of completing successful PV power plant business projects. In Japan, JAG Energy has built a number of PV power plants, including the Sakaide Solar Way in Sakaide City, Kagawa Prefecture, and the Miyazaki Solar Way in Tsuno-cho, Miyazaki Prefecture.

About TÜV Rheinland:

TÜV Rheinland is a global leader in independent inspection services, founded more than 140 years ago. The group maintains a presence in 65 countries with 17,200 employees. Independent TÜV Rheinland experts stand for quality, efficiency and safety for people, technology and the environment in nearly all aspects of life.Since 2006, TÜV Rheinland has been a member of the United Nations Global Compact to promote sustainability and combat corruption.

Solutions, results

Based on the results of the technical inspections performed by TÜV Rheinland Japan, Shinsei Bank was convinced that good returns could be expected and therefore decided to finance the project. Until now, PV power plant projects in Japan have been financed primarily through corporate loans. As the scale of these projects has dramatically increased, so has the risk and complexity of standard financing practices. In this case, project financing became possible only because TÜV Rheinland Japan was able to independently verify the bankability of the project.
