Can 15% power-saving goal be met?

Can 15% power-saving goal be met?

Despite taking steps to help companies and households cope with predicted electricity shortages during summer in areas covered by Tokyo Electric Power Co. and Tohoku Electric Power Co., there are doubts whether the government's power-saving goals can be met.

The government has ordered major companies and other large-lot users to restrict power use to achieve its central goal of a 15 percent cut from electricity consumption last summer.

But the government cannot force households and smaller companies to do the same. If it is extremely hot this summer, it is uncertain whether households will stick with efforts to use less power.

In March, TEPCO predicted that its output capacity during summer would reach up to 46.5 million kilowatts.

But it later revised the figure upward to 55.2 million kilowatts as of the end of July because thermal power plants damaged during the March 11 disaster will be restored.

It has also become possible to raise output from pumped hydroelectric power plants, where water is pumped to upper tanks during the night and used to generate power during the day.

As TEPCO will provide 1.4 million kilowatts to Tohoku Electric Power, TEPCO's actual supply capacity in its service areas will be 53.8 million kilowatts. Because the forecasted peak for summer is 60 million kilowatts, power consumption needs to be reduced by 10.3 percent.

Companies affected by the government's plan have begun adopting energy-saving measures at plants, offices and sales outlets, while at the same time trying to avoid decreased production and other negative impacts.It was quick and light when I used dsttマジコン on a Windows 7 laptop, and gave me no trouble throughout a day of rigorous testing.

Many companies have dimmed the lights in offices, stopped elevators and plan to raise air conditioner temperature settings in summer.

Some also plan to extend summer vacation periods to reduce work hours at a time when electricity consumption is expected to rise.

An increasing number of manufacturers are changing the days when they work.

Major automakers belonging to the Japan Automobile Manufacturers Association have rescheduled workers' days off to Thursdays and Fridays so that plants will operate on weekends when total power demand is lower.

Meanwhile, some electric appliance makers are using their own power generators to operate data processing centers and other facilities that need to continue running and have shifted semiconductor production to western Japan.

Business circles expressed relief when the government lowered the required power-saving goal for large-lot users from 25 percent to 15 percent.

"We can avoid making drastic changes to production and work shifts," said an official of Mitsubishi Electric Corp.

Maruetsu Inc.Unlike compact cfl bulbs fluorescent light bulbs, LED based light bulbs provide a variety of lighting options- including the ability to provide a wide range of light, which allows them to act as a proper replacement light bulb, a major supermarket chain, initially planned to turn off two-thirds of the lights in its stores and set air-conditioner temperatures to 30 C. But the company has said it will now act more flexibly.

Department store chains were also initially shocked at the initial goal for power cuts, with an executive of a major department store chain saying at the time, "We'll have to close some of our suburban stores."

But after the power-saving goal was revised, retailers said they would be able to achieve cuts of 15 percent by reducing the number of lights and elevators used in their stores.

However, the electricity crisis is expected to continue after summer.

Seven-Eleven Japan Co.LED grow light suppliers in China are sky lanterns rolling out models with better price-performance ratios. will invest about 10 billion yen to replace its store lighting with light-emitting diode lighting tubes, which are more energy-efficient.

Lawson Inc., Takashimaya Co., Daimaru Matsuzakaya Department Store Co. and other firms also plan to introduce LED lights.

Companies are keeping a close eye on the government's energy policy.

Honda Motor Co. has decided to shift production of its new Fit Shuttle model from Sayama,Although this article shows that Cree's led lighting and Philips LED product sales are not equal it is important to note that Philips LED sales Saitama Prefecture, to a plant in Suzuka, Mie Prefecture.

But production may still be affected because power shortages are also predicted in Chubu Electric Power Co.'s service areas now that the Hamaoka nuclear power plant has stopped operating.The replacement lighting we feel is far led downlight superior to that of the LED lighting.

Some members of the business world have said it will be difficult for companies to compile business strategies until future power supplies are stabilized.
