Tokyo Electric Power Co.’s fuel-oil consumption increased nearly three-fold in June because of a higher dependence on thermal power generation after the Fukushima nuclear disaster.

The utility known as Tepco used 539,000 kiloliters of fuel oil last month, up from 192,000 kiloliters in the same period last year, according to data released today on its website.

Tepco’s crude oil consumption more than doubled to 231,000 kiloliters, while coal use increased about 13 percent to 211,000 metric tons. Liquefied-natural-gas consumption fell about 6 percent to 1.7 million tons.

Japan ended a two-month period without an operating reactor on July 1 when a unit at Kansai Electric Power Co. (9503)’s Ohi plant in western Japan was restarted. Tepco has had no operating reactors since it halted the No. 6 reactor at its Kashiwazaki Kariwa atomic station in northwest Japan’s Niigata prefecture on March 26 for scheduled maintenance.

The following table shows Tepco’s consumption and purchases of fuel oil, crude, LNG and coal for June. For fuel oil and crude, the volume is in kiloliters while LNG and coal are in tons.
