Renewable Energy Initiatives
For a Sustainable Society
We are now facing serious environmental problems, such as global warming and air pollution. Protecting environment and contributing for a sustainable society is being urgent social challenges. Our renewable energy business is one of our initiatives to solve these social challenges within our medium- to long-germ environmental vision, Obayashi Green Vision 2050.
Our Next Generation Energy Businesses
Amid changes in energy related fields, we established Obayashi Clean Energy Corporation in July 2012 to diversify our earnings base. We are generating electricity from renewable energy sources. We began operation of solar, biomass, onshore/offshore wind power generation, and now promoting to start geothermal power and hydroelectric power generation businesses. These renewable energy businesses are one of our four strengthening pillars of Obayashi Medium-Term Business Plan 2017.
Through our initiatives, we are able to solve social challenges and realize a sustainable society. We accumulate our EPC (Engineering, Procurement and Construction) knowhow of energy business, and are getting ready to provide a best solution for our customer's request related to next generation energy.
