Because TEPCO's facilities have been seriously damaged, power shortage
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.
