Nippon Yusen Kaisha

Nippon Yusen Kaisha (NYK), one of the world’s premier shipping and logistics companies, installed a solar project at its Yusen Tokyo container terminal, located at Ooi (pronounced "OH-ee") wharf, adjacent to Tokyo Bay. This was the first installation of CIS modules at any port facility in Japan. While NYK has experience in photovoltaic technology, having embarked on long-term testing of solar panels for potential use on shipping vessels, this was also the first time for the company to employ thin-film modules.


The electricity generated from the system corresponds to 1 percent of electricity consumption at the container terminal. NYK sells a portion of the power generated to other users at the terminal, qualifying the company for the green electric power certificate. This shows that electricity is generated from renewable sources.


The Tokyo government plans to promote the installation of other PV systems in related facilities around the Tokyo Bay area. The proximity to the sea means there are no high buildings to interrupt sunlight, making it an attractive area for future renewable energy development. In addition, NYK is considering expanding the use of PV systems — in particular CIS modules — to its various warehousing and terminal facilities around the world.
