Could Japan survive without nuclear power? The short answer to that question is yes.
Japan has been surviving surprisingly well without nuclear power for the last four years. Following the Fukushima disaster in March 2011 all of Japan’s 48 other nuclear reactors were shut down. The predicted blackouts did not happen, the country kept running just fine.
But there has been a cost. Prior to the Fukushima disaster nearly 30% of power came from nuclear. That has been replaced by burning lots more coal and gas – Japan is now the world’s biggest importer of liquefied natural gas.
But desperate times called for desperate measures. Following the Fukushima disaster, the Democratic Party government enacted a “feed-in tariff”.
Anyone could put solar panels on their roof, connect up to the grid and the power companies would be required to pay them a generous 40 Yen per kilowatt.
The response was dramatic. Money poured in to solar, and not just on people’s rooftops. In 2011 Japan had just 4.9 gigawatts of installed solar capacity. Just three years later, at the end of 2014, that had leapt to 23GW. It put Japan ahead of Italy as the number three solar energy producer in the world.
In November 2013 electronics giant Kyocera began producing power from Japan’s biggest solar array so far, nearly 1.5 square kilometres of panels built on the site an old shipyard in Kagoshima bay. It can produce 70MW of power, enough to power more than 20,000 homes.
That is just the beginning. The company has plans to build a 430MW plant on one of Japan’s many offshore islands, big enough to power 130,000 homes.
It’s all great news, except it has all suddenly ground to a halt.
At the end of last year Japan’s big power companies began telling solar producers they could take no more electricity from them. At the same time the government dropped the price utilities would have to pay for electricity from new solar to 27 Yen per kilowatt.
Suddenly the calculus for building more solar has been put in serious doubt.
No-one is suggesting a conspiracy. But the timing is significant.
In the face of widespread opposition, the Abe government is pushing ahead with a return to nuclear power. His most persuasive argument for doing so is that Japan needs the cheap reliable “base load” power that only nuclear can provide.
