Effects or Remarks

E-21

An example of on-site energy service project at a high-end film factory
1. For an industrial customer, a high efficiency system was created to meet the customer's energy
requirements.
2. Production loss was reduced by eliminating the effect of momentary voltage drop on production facilities
with installation of a gas turbine and a large-scale UPS (the largest in Japan).
3. The customer was able to concentrate management resources on their producing department by
outsourcing of the operation and maintenance for utility supply facilities.
• Maximizes energy efficiency(91%: world-class level)
