On July 1, the government started imposing a 15 percent power consumption cut on large-lot users serviced by Tokyo Electric Power Co. and Tohoku Electric Power Co. Small-lot users, including households, are also called on to reduce power consumption by 15 percent. Other power companies are also calling on companies and people to save power. The accidents at Tepco's Fukushima No. 1 nuclear power plant have made the electricity saving efforts necessary.
