The Albany Gazette - Japan issues power warning after quake hits supply

Overnight, the government issued its first-ever electricity crunch warning for the capital and other regions, with supply dented because several thermal power plants remain offline after the quake.

The industry ministry called on people to conserve energy throughout Tuesday, but with sporadic snowfall and unseasonably cold temperatures in the capital, demand remained strong.

"We're only achieving power-saving of around 1.5 million kilowatts, which is two to 3.5 million kilowatts less than the target level," warned Koichi Hagiuda, Japan's minister of economy, trade and industry.

"If this continues, we are unfortunately approaching a situation where we will have to carry out widespread power cuts, as we did on the day of the earthquake, in order to prevent a total blackout."

The crunch is believed to be the toughest power situation in the Tokyo area since March 2011, when rolling blackouts were instituted after a quake-triggered tsunami crippled the Fukushima nuclear plant and other nuclear facilities were shut down.

The current supply shortages have been caused in part by a powerful 7.4-magnitude earthquake off northeast Japan last week that killed at least two people and damaged several thermal power plants.

Operations at six plants are currently suspended because of damage to boilers, transformers and turbines, an industry ministry official told AFP.

While some are expected to resume operation by the end of March, for others the repairs could take several months, the official said.

The tight supply comes as temperatures in Tokyo hovered as low as two degrees Celsius (35 Fahrenheit), unseasonably cold and far below temperatures seen in recent weeks.
