Data (as of 2005)

• Introduced capacity: 520,000 kW (730,000 kl crude oil equivalent)
• 18 sites nationwide
• Power generation cost: Approx. ¥9–12/kWh (note)
• CO₂ reduction cost (estimate): Approx. ¥2,500 – 24,200/t-CO₂

(Source) Estimated by the Study Group on Geothermal Power Generation (March 2009) on the basis of the results of the Geothermal Development Promotion Survey (strategic nationwide survey) (Implemented by NEDO in FY2001)

Target

• Increase in introduced capacity to approx. 530,000 kW by 2020

Characteristics

• Stable power generation is possible and technologically matured
• Abundant in the country

Issues

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

Present promotion measures for introduction

• Subsidies (for business and public facilities)
• RPS (in the case of those that does not dramatically reduce hot water)
