The length of Power Purchase Agreements (PPAs) for geothermal energy in Japan is forecasted to gradually increase from 19 years in 2024 to 21 years by 2028. This represents an incremental year-on-year increase, with notable growth observed from 2026 onwards. The baseline in 2023, however, is not provided, but the trend suggests a steady rise.
The future trends to watch for include the potential continuation of this extension in PPA durations, which may be driven by advancing technology, improved efficiency in geothermal energy production, and favorable regulatory frameworks promoting long-term investments in renewable energy in Japan.
