Report on Power Saving Initiatives of the Fujitsu Group

Achieved over 20% energy savings during the summer at Fujitsu locations serviced by Tokyo Electric Power Company and Tohoku Electric Power

Fujitsu Limited

Tokyo, September 21, 2011

The Fujitsu Group today announced that it had succeeded in reducing year-on-year power consumption by 20% to 41%, depending on business site, in areas serviced by Tokyo Electric Power Company and Tohoku Electric Power. This marks a substantial increase over the 15% cuts directed by the Japanese government for the July to September 2011 period. In addition, Fujitsu offices and factories serviced by The Kansai Electric Power Company reduced power consumption by over 10%, as directed by the government.

Power conservation measures were implemented in Fujitsu Group locations in Japan, led by large-scale sites in areas serviced by Tokyo Electric Power Company, Tohoku Electric Power and The Kansai Electric Power Company where it was necessary to comply with legal regulations and government directives, as well as Fujitsu plants and tenant office buildings nationwide. In addition, business sites required to comply with regulations in Tokyo Electric Power Company and Tohoku Electric Power service areas used ICT to observe electricity usage in real time as they steadfastly worked to achieve their goals.

Main Power Saving Initiatives of the Fujitsu Group

  1. Approximately 3,600 of the roughly 10,000 servers used for Fujitsu's development and business operations were either relocated to datacenters outside the regions serviced by Tokyo Electric Power Company and Tohoku Electric Power, or had usage temporarily suspended.
  2. Fujitsu reduced the number of production facilities and shifted operations of some manufacturing processes to nighttime.
  3. At its buildings and offices based in commercial buildings that it occupies as a tenant, Fujitsu curtailed the use of elevators and lighting, adjusted the temperature of air conditioners, and suspended the use of water heaters and refrigerators.
  4. At the Numazu Plant (Numazu City, Shizuoka Prefecture), power supply was obtained from a private power generator.
  5. At company business sites, two public holidays that normally would be observed in autumn or later was instead be taken as holidays in July or August, which was expected to be the period of peak electricity consumption. Combining these two holidays with a weekend, each location took turns in observing a four-day long weekend.

Fujitsu will continue to implement power-saving initiatives such as the curtailment of elevator and lighting use, and the adjustment of air conditioner temperatures, even after the government directive has expired. Together with these efforts, Fujitsu will work to boost energy efficiency even further as a part of its Green ICT activities.
