TOKYO, April 8 (Reuters) - The Tokyo Stock Exchange said it will delay a plan to extend trading hours from May 9 to reduce power consumption, as Japan seeks to save electricity in Tokyo and northern prefectures in anticipation of peak summer demand.
The bourse said it will push back the plan until the autumn, when households and offices turn off air conditioners as temperatures fall.
Capacity has been squeezed at Tokyo Electric Power Co. and Tohoku Electric Power Co because the March 11 earthquake and tsunami knocked out power plants including Tokyo Electric's stricken Daiichi nuclear plant in Fukushima. (Reporting by Tim Kelly; Editing by Edmund Klamann)
