The Osaka-based company estimated the total costs to fill the void left by nuclear reactors shut for safety checks would total more than 1.
7 trillion yen for the year ending March 2013, up from 1.3 trillion yen this fiscal year, according to a presentation on its website.
Only two of Japans 54 nuclear reactors remain online after the March 11, 2011, quake and tsunami crippled Tokyo Electric Power Co.s Fukushima Dai-Ichi nuclear station. The government has said it wont approve the restart of reactors, even if they pass so-called stress tests, unless local authorities agree.
Kansai Electrics crude oil consumption in the year ending March is estimated to be nearly 5 million kiloliters 31.4 million barrels while use of liquefied natural gas is expected to reach about 7.3 million tons, which is the capacity of its facilities.
The companys maximum supply capacity this summer without nuclear power is estimated at 23.98 million kilowatts, the presentation said. Thats 13.9 percent less than the 27.84 million kilowatts of peak electricity demand last summer in the Kansai region that includes the cities of Osaka, Kyoto and Kobe.
Based on that forecast, the utility expects 41 days of power shortages between July and September.
