Shimizu Corp. Develops Next-Generation Distributed Power Supply System

Strategic Insights -

Shimizu Corp. has designed a innovative power supply system aimed at conserving energy in office buildings, plants, and other structures. The system allows multiple small-scale power sources, such as wind turbines and gas engines, to be linked together, potentially cutting power costs by 30%. This development is part of Shimizu's efforts to provide a stable supply of energy at a low cost.

Key Takeaways:

  • The system enables the integration of multiple small-scale power sources, including wind turbines and gas engines, to reduce power costs by up to 30%.
  • The system operates by controlling multiple low-output power sources as a single unit through a computer, allowing for efficient energy distribution.
  • The system will be launched with a marketing campaign in the coming fiscal year, targeting urban redevelopment areas and industrialized regions.
  • Multiple companies can contribute equipment and jointly use facilities, reducing investment costs.
  • Shimizu plans to install the first practical system at its own technology research site by the end of the year, with a total maximum output of approximately 600kw.
  • The system is designed to supply one-quarter of the electricity used at the research site, featuring a combination of gas engine and rechargeable battery equipment.
  • Shimizu aims to keep prices low enough for firms to recover their initial investments, including equipment costs, within five years.

Statistics:

  • Potential power cost reduction: 30%
  • Number of companies anticipated to contribute equipment: Multiple
  • Maximum output of the first practical system: Approximately 600kw
  • Percentage of electricity to be supplied: One-quarter
  • Target recovery period for initial investments: Five years
  • Date of planned installation at Shimizu's technology research site: End of the year
