Status by Energy Source

Photovoltaic (PV) Power Generation

Data (as of 2005)

• Introduced capacity: Approx. 1.42 million kW ( 0.35 million kl crude oil equivalent)
• Power generation cost: Approx. ¥49/kWh
• CO₂reduction cost (estimate): Approx. ¥69,000/t-CO₂

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

• Increase in introduced capacity by about 20 times compared to FY 2005 in around 2020
• Reduction in system price by about half in 3-5 years (policy target)

Characteristics

• Drastic reductions in power generation costs are expected.
• Potential introduced capacity is large for both household and non-household purposes (can be introduced by an individual).
• The industrial base is broad.

Issues

• Power generation cost is higher than that in other power generation systems.
• Requires system stabilization measures due to output instability

Present promotion measures for introduction

• Subsidies (for household/business facilities/public facilities)
• Taxation
• Excess electricity purchase systems (FIT)
• Renewable Portfolio Standard (RPS)(limited to those not adopting Feed-in Tariff (FIT))
• R & D/demonstration tests
