Present Status and Promotion Measures for the introduction of Renewable Energy in Japan

Status by Energy Source : Hydroelectric Power Generation

Data (as of 2005)

  • Introduced capacity: Approx. 45.74 million kW (17.32 million kl crude oil equivalent)
  • Power generation cost: Approx. ¥8-13/kWh
  • CO2reduction cost (estimate): Approx. ¥800-9,200/t-CO2

Outlook of long-term energy demand (case of optimal introduction)

  • Increase in introduced capacity to approx. 49.24 million kW in 2020

Characteristics

  • Stable generation is possible and is technologically mature.
  • Increasing interest in small and medium hydropower generation.

Issues

  • Plant sites are largely restricted.
  • Power generation cost is likely to increase in a step-wise manner.

Present promotion measures for introduction

  • Subsidy (for business and public facilities)
  • RPS (hydroelectric power plants of less than 1,000 kW)
