Japan shut down its 54 nuclear reactors after a tsunami triggered a meltdown at the Daiichi plant in March 2011. Only two reactors have come back online since. The loss of nuclear capacity has created an opening for more renewable sources in Japan. The New Scientist reported that Japan is preparing to build the world’s largest offshore wind farm, starting July 2013. The plan would see 143 wind turbines built on platforms 16 km off the coast of Fukushima by 2020. The farm would generate 1GW of power once completed. If built, the Fukushima farm would overpower the first phase of the London Array in the Thames Estuary, where 175 turbines will generate 630MW of electricity when fully operational later this year. The London Array is due, eventually, to have a second phase – of 370MW – taking its overall capacity also to 1GW.
According to Suchitra Sriram , Program Manager, Energy and Environment, Frost & Sullivan, "The shutdown of Japan's nuclear reactors in the aftermath of the earthquake and tsunami has changed the perspectives towards renewable energy technologies. The compelling need for energy self sufficiency and energy security has driven Japan to tap its offshore wind potential despite high costs and challenges in connecting to the power grid. Furthermore, Japan's investments in developing its onshore wind power projects have been dismal since 2008 due to complicated construction guidelines and grid connection issues,". As per Frost & Sullivan, the wind energy industry, one of the key growth engines amongst renewable energy technologies slipped into a slowdown in 2012 plagued by Europe's and other developed countries' economic woes, its first since witnessing double digit growth rate y-o-y since 2009. Amidst this, the wind energy industry is likely to regain its lost sheen back in 2013 with the extension of federal tax credit in the US and Japan's recent announcement to invest in offshore wind farms in Fukushima. Despite falling prices and technological advancements, the wind power market growth continues to be fuelled by extensive government support. Unlike the European markets that led the offshore wind power development globally, the Asia Pacific region has been slow progressing. However, with Japan's plan to aggressively promote offshore wind projects in the country, the focus of developing offshore wind farms is expected to shift from the West to the East. A prime example is the Fukushima offshore wind power project with a mammoth planned capacity of 1 GW. The project has proved how wind power can be harnessed effectively even to replace nuclear power plants that are currently mired in safety concerns. Besides, it highlights the role played by such renewable energy technologies in locations that are highly susceptible to develop nuclear power plants. This project, once commissioned has the potential to push Japan as one of the leading wind power markets in the Asia Pacific region."
