Because TEPCO's facilities have been seriously damaged, power shortage 
may occur.
TEPCO appreciates customers' cooperation in reducing electricity usage by 
avoiding using unnessesary lighting and electrical equipment.
We are also making requests to some large-scale customers with contracts 
to partially suspend operation to suppress usage of power.
We are taking all measures to restore power, however, we expect extremely 
challenging situation in power supply for tomorrow as well.
We kindly ask our customers to cooperate with us in reducing usage of power.
Please do NOT touch cut-off electric wires.
A temporary small fire occured at a service building in Fukushima Daini 
Nuclear Power Station. However, it was extinguished at 4:07 PM today.
