CBI member, Mott MacDonald has completed work on the Setouchi Kirei solar power plant in Japan. The 235MW plant is now the biggest operating solar plant in Japan and will operate as a clean source of energy for a minimum of 20 years. The plant, along the sea-front in the eastern city of Setouchi, has further green credentials, having been built to incorporate a seawall that positions the solar plant as a barrier protecting an existing habitat area of rare species; including the marsh harrier and black-faced spoonbill bird.
Mott MacDonald was responsible for overseeing the construction and managing operation costs of the plant, carried out plant performance and energy yield assessments, and due diligence of design checks on the project.
Project manager Tatsu Kikuchi said: “[Mott MacDonald are proud to be a part of creating the largest solar power plant in Japan. The plant will cut 192,000 tonnes of CO2 emissions, which is half of Setouchi’s current emissions” and create enough energy to power about 80,000 households.
The site consists of 900,000 solar panels over 260 hectares. Thought was given to the location of the plant, ensuring that the plant maximises the benefit it brings for Setouchi city. The plant is located on Setouchi’s former salt fields – previously the largest salt field sites in East Asia until closure in 1970 – making the salt fields area productive for the first time in over 40 years.
The plant plays a further role in protecting Japan’s endangered black-faced spoonbill. The bird is restricted to coastal East Asia, and migrates to Japan during the winter. Major preservation efforts are taking place across South Korea and Japan to protect the birds, who were classified as ‘critically endangered’ in 1990. Their situation has improved, and the birds are now considered ‘endangered.’
Protecting wildlife, rejuvenating areas of un-used land, and cutting CO2 emissions, the Setouchi plant is pioneering in its approach to commercial energy generation. Mott MacDonald hopes this model will soon become the norm in Japan. The consultancy is working hard to improve the accuracy of solar resource estimation systems in Japan, which are vital to securing investment from lenders, and financing the spread of similar environmentally friendly green-energy initiatives.
