Japan may be without atomic- generated electricity for the first time in more than four decades next month when its last reactor still running after the Fukushima nuclear disaster shuts for maintenance.
Since the crisis on March 11 last year, 53 of Japan’s 54 reactors have been shut either owing to damage from the earthquake and tsunami, government order, or mandatory maintenance. The plants provided 30 percent of the country’s electricity prior to March 11. The last one running on the northern island of Hokkaido goes offline from May 5.
Japan may “momentarily” be without atomic power from that date, the Mainichi newspaper cited Industry Minister Yukio Edano as saying on April 15 after he spent the weekend in western Japan and failed to get immediate agreement from local authorities that reactors run by Kansai Electric Power Co. (9503) in Fukui prefecture passed safety tests and should restart.
“Whether or not we can restart the reactors depends on future discussions,” he said at a Tokyo news conference today.
The utilities powering the world’s third biggest economy have been forced to turn to coal, oil and gas-fired power plants to keep factories, offices and households supplied with electricity. Buying and importing those fuels is driving up costs and may lead to higher electricity bills and another drag on an economy that’s contracted in three of the last four years.
“Ultimately, the Japanese citizen will be most affected by the delay in the restarts in paying higher electricity bills,” said Tomoko Murakami, a Tokyo-based nuclear analyst at the Institute of Energy Economics, Japan.
Record LNG Imports
Japan’s 10 regional power utilities bought record amounts of liquefied natural gas last year to replace nuclear, or 52.9 million metric tons of LNG in the fiscal year ended in March, up 27 percent from the prior year, according to data yesterday from the Federation of Electric Power (9501) Companies.
Use of petroleum, which includes crude and fuel oil, more than doubled to 23.3 million kiloliters (147 million barrels), according to the federation’s data. Petroleum consumption was the highest in at least 10 years.
Fuel costs at the nine regional utilities that have atomic plants -- Okinawa Electric Power Co. is the exception -- may more than double to about 7 trillion yen ($86.5 billion) in the year ending March 2013 if reactors remain shut, according to an April 9 report by the trade and industry ministry. Kansai Electric’s fuel bills may rise by 800 billion yen to about 1.1 trillion yen, it said.
The country will have no reactor in operation for the first time since May 1970 if Hokkaido Electric Power Co. (9509)’s Tomari No. 3 reactor is taken offline before Kansai Electric starts two reactors at its Ohi plant in Fukui, said Tetsu Oshikiri, a spokesman for the Federation of Electric Power Companies of Japan, in Tokyo yesterday.
Power companies usually take about 10 days to start an idled reactor, Tomoe Sugimori, a spokeswoman for Kansai Electric, said by telephone. That means local lawmakers would need to approve a restart by April 25 for the Ohi reactors to be online before the Tomari unit shuts.
“We can’t set a deadline on when the government can get the cooperation of local governments on the restarts,” Chief Cabinet Secretary Osamu Fujimura said at a news conference in Tokyo yesterday.
Economy of Mexico
The Ohi atomic plant is located about 95 kilometers (59 miles) northeast of Osaka, the nation’s second-biggest metropolitan area. It help power the Kansai area of western Japan that’s about the size of Belgium, has an economy worth $1 trillion -- similar in size to Mexico’s -- and is home to the cities of Osaka and Kyoto as well as factories of Sharp Corp. and Panasonic Corp. (6752)
Kansai Electric’s output without nuclear power may be 18.4 percent short of peak demand this summer if Japan is hit by a heat wave similar to the one in 2010, the national government said in a statement April 13, revising down its April 9 forecast of 19.6 percent.
The utility would need to turn on half of its 11 reactors to avoid the summer power shortages forecast under the government’s worst case scenario, Murakami at Energy Economics said. Restarting that number of reactors is very unlikely, she said.
‘Rush to Restart’
The governor of Shiga prefecture adjoining Fukui criticized the government for what she called the “rush to restart the reactors” in an April 11 interview. The government’s earlier power shortage forecast was flawed as it was based on Japan’s hottest summer in at least 113 years and ignored power savings and private electricity generation capacity, Shiga Governor Yukiko Kada said.
Kada and the governor of Kyoto prefecture, also adjoining Fukui, held a joint press conference today and said an independent body should assess electricity supply and demand, Kyodo News reported.
The government has already decided to do that and will set power saving targets once the independent review is complete, cabinet secretary Fujimura said today.
Pending the release, it may be necessary to prepare a plan on scheduled blackouts, Edano said today.
“If we can be certain we can fill the gap between demand and supply, blackouts won’t be necessary,” he said.
Japan had rolling blackouts last year in some areas where Tokyo Electric Power Co. supplies electricity after the March 11 quake and tsunami shut power plants, including the Fukushima Dai-Ichi nuclear station.
A poll suggests Edano, who steered Japan through the early days of the Fukushima disaster as chief cabinet secretary, will win agreement in Fukui prefecture to start the Ohi reactors. More than 90 percent of local lawmakers favor the plan, the Mainichi newspaper said April 10, citing its own survey.
The Ohi reactors would be the first to come back online since Japan adopted so-called nuclear stress tests or computer simulations to assess each plant’s ability to withstand earthquakes, tsunamis and to supply backup power to keep reactor cooling systems running.
The failure of backup power at Tokyo Electric Power Co.’s Fukushima Dai-Ichi station on March 11 last year caused the worst atomic accident since Chernobyl in 1986 and radiation fallout that forced the evacuation of about 160,000 people.
Winning over authorities in Fukui may help the government convince other local regions hosting atomic plants to resume operations before power demand peaks in summer months.
While the government may get local approval to turn on the Ohi reactors, the extent of the Fukushima radiation fallout --it covered an area about half the size of New York City -- is worrying neighboring areas.
Shiga Governor Kada said the Fukushima disaster suggests Shiga may be affected by radiation in the event of a nuclear accident at the Ohi plant.
In a survey by Greenpeace Japan of 3,000 people living in the neighboring prefectures of Osaka, Kyoto and Shiga, 75.6 percent of the respondents said the government’s decision to allow reactor restarts is too hasty.
About 82 percent said the central and local governments’ measures to deal with a nuclear disaster are inadequate, the environmental group said April 11, citing the poll results.
