Tokyo Electric Power Co. reported a group net loss of ¥685.29 billion for the business year ended in March, its third straight year in the red due to the Fukushima nuclear crisis.

The utility did not release a forecast for this year amid uncertainties over its business conditions, but returning to a profit soon will be difficult under the 10-year restructuring plan authorized by the government last May.

The operator of the stricken Fukushima No. 1 nuclear plant lost less money last year after hemorrhaging ¥781.64 billion in the 2011 business year.
