But perhaps not for long. The production of nuclear power, which accounts for about 30% of Japan's electricity, has stalled as workers try to avert a nuclear disaster following last week's earthquake.
The power disruptions have helped send natural gas futures rallying on speculation that liquefied natural gas cargoes would be diverted to Japan.
On Tuesday, natural gas futures rallied for a third day, gaining 1.2% in the New York Mercantile Exchange to $3.959 a million British thermal units. Despite the recent rise, gas is still down 11% this year.
