The Executive Yuan said the decision was made to reduce the burden on power reserves after the collapse of power plant towers in Hualien took out generation capacity during peak season.The damage is expected to take two weeks to repair.
Spokesman Hsu Kuo-yung urged Taiwan to switch off the air conditioner from 1 p.m. to 3 p.m. — the hottest hours of the day.
Hsu said the Executive Yuan hoped to set an example and invited office workers to join its campaign, using a fan instead of air-conditioning units to save electricity.
Taiwan's power supply is facing a critical challenge in the wake of Typhoon Nesat, which destroyed infrastructure that has taken out 1.3 million kilowatts in capacity.
The Presidential Office has apparently already begun the effort, with Presidential Office Spokeswoman Chang Wen-lan appearing in the press room to declare that the air conditioning would be suspended.
Dismayed reporters asked if they could switch it on secretly later, but Chang said the cooling system was controlled by a central switch.
Taiwan Power Company said Monday that the power reserve indicator was flashing red, meaning that electricity reserves were below 900,000 kilowatts.
