The Fujitsu Group announced a comprehensive strategy for reducing its peak power usage by 15% between July and September of 2011 in areas serviced by Tokyo Electric Power Company and Tohoku Electric Power. The Japanese government has called on all large-scale power users to reduce their consumption of electricity from the grid by 15%.
Fujitsu is a producer of air-conditioners, consumer electronics, microelectronics, and telecommunications equipment.
The company will move or temporarily suspend usage of 3600 servers in the impacted region. Fujitsu has about 10,000 servers serving its business operations and located in its the Kawasaki Research & Manufacturing Facilities in Kawasaki City; Fujitsu Solutions Square in Tokyo; and Makuhari System Laboratory in Chiba City.
Reducing the number of production facilities and shifting some manufacturing processes to nighttime will reduce its peak daytime power consumption without impacting production schedules, Fujitsu said. Affected plants include Nasu Plant in Ohtawara City and Oyama Plant in Oyama City.
The company will also continue comprehensive power-saving measures that have already been implemented, including curtailing elevator and lighting use, adjusting air-conditioning temperatures, and suspending the use of water heaters and refrigerators in some buildings and offices. Fujitsu's Japanese Cool Biz workplace attire program will now be extended to last from May through October. The company will also employ smart power outlets and use the peak-shift control functionality of notebook PCs, to automatically switch the machines to battery operations.
The power supply at the Numazu Plant in Numazu City will be shifted to a private power generator during peak power usage periods.
The company will also reduce staff, and thus electricity demand, by shifting two public holidays that normally would be observed in autumn to July and August. Other time-off schedules will be shifted to reduce building occupancy during the peak-demand July and August months.
The company will also make the status of electricity usage visible in real time, allowing it to monitor electricity conservation and ensure that power consumption during peak periods is limited.
