The Japanese market has remained highly dynamic over the last months. Solar portfolios, while not yet following Europe’s example of an active secondary market for operational assets, are steadily growing almost exclusively due to new plant coming on line.
 
Below we can share with you a new overview of the largest operational Solar PV portfolios in Japan, together accounting for roughly 3.3 GW of installed capacity. To access the full overview, please use the download link at the bottom of this page.



We make these observations (based on available data):

  • Mitsui & Co., Ltd. now (co-)owns the largest portfolio in Japan. This is partly because of its extensive cooperation with SB Energy and Tokyo Marine Asset Management Co.
  • Eurus Energy Holdings shows a remarkable growth in its portfolio, mostly due to its massive 115 MW power plant in Aomori Rokkasho village. This is also Japan’s largest single PV plant.
  • Twelve out of the 30 largest portfolios have most of their plants located in Hokkaido, Japan’s second largest island and its northernmost prefecture. Low population density and the high availability of flat land has made this area the most popular so far for mega solar plants.
  •  Average plant sizes in the portfolios vary significantly, ranging from 0.54 MWp to 20.2 MWp. Across the 10 largest portfolios the average size is 12.5 MWp; and across the 30 largest portfolios it is 7.4 MWp. Overall this reveals that in Japan the larger portfolios consist on average of the larger plants.
  • All portfolios in the Top-10 are larger than 140 MWp, while the 3 largest portfolios accounts for over 200 MWp each.
  • Portfolios are made up of plants of very different sizes. For instance: Eurus Energy Holdings owns a 115 MW plant but also a 1 MW plant, and SB Energy co-owns a 111 MW plant but also a 1.1 MW plant.
  • Only 13 out of the 30 largest portfolios are fully owned by one company. The 17 remaining portfolios have certain levels of shared ownership, ranging between 3% and 100%.
  • The 30 largest portfolios account for 2.579 GWp of installed capacity, of which nearly 60% (1.417 GWp) is held by the 10 largest portfolios

- The data used in this overview is publicly available and might not be entirely complete as some companies do not share all numbers. If you believe you can offer more accurate data, please send us an email (marketing@solarplaza.com) so that we can improve this overview.
- n several cases ownership of assets or portfolios is shared between different companies, which is hard to represent in this overview. We have thereby included one additional column in the table, indicating if the portfolio is owned by more companies and, if so, what share.
