The Ministry of Economy, Trade and Industry intends this month to end Tokyo Electric Power Co.'s rolling blackouts, sources said Wednesday.

To conserve power, METI plans to instead urge large-lot corporate users to limit their use of electricity in the summer, when demand typically peaks because of the need for air conditioning, the sources said. The ministry will aim to slash demand 25 percent from last summer, they said.

If the plan is enforced, it would be the first time for Japan to invoke such compulsory power consumption restrictions since the oil crisis in 1974.
