The 2032-2034 Post-FIT Wave Is Approaching
FIT Launched
Feed-in Tariff scheme starts
Initial rate: ¥40/kWh
100 GW Milestone
Cumulative solar capacity
surpasses 100 GW
FIT/FIP Abolished
New ground-mounted solar
FIT/FIP support ends
Post-FIT Wave
Early FIT projects expire
in succession (through 2034)
Early FIT projects certified and commissioned in 2012-2014 will reach the end of their 20-year fixed-price purchase period in 2032-2034. Japan's cumulative solar capacity surpassed 100 GW in 2024, with early FIT projects accounting for tens of gigawatts. Compounding this, the abolition of FIT/FIP support for new ground-mounted solar from FY2027 means that maximizing revenue from existing power plants will be the defining challenge of Japan's renewable energy market over the next decade.
Post-FIT options fall into three broad categories: continuing to sell electricity to utilities at post-FIT rates, transitioning to the FIP scheme (market price + premium), and converting to corporate PPA or self-consumption. This article quantitatively compares each strategy using IRR analysis and identifies optimal approaches based on area-specific market characteristics.
| Strategy | Revenue Rate | IRR (Estimate) | Revenue Stability | Suitable Scale |
|---|
| Utility sale continuation | ¥7-9/kWh | 2-4% | High (fixed) | All scales |
| FIP transition | ¥10-14/kWh | 5-8% | Medium (market-linked) | 250kW+ |
| Corporate PPA (10-year) | ¥14-18/kWh | 7-10% | High (fixed) | 1MW+ |
| Self-consumption (+ BESS) | ¥22-26/kWh equivalent | 8-12% | Medium (electricity rate-linked) | All scales |
| Repowering + FIP + BESS | Composite revenue | 10-14% | Medium-High | 500kW+ |
Area-Specific Optimal Strategy Map
| Area | Market Characteristics | Recommended Strategy | Key Considerations |
|---|
| Hokkaido | High wind, high RE ratio | FIP + BESS | Winter demand stabilizes prices |
| Tohoku | Abundant RE, dispersed demand | FIP + Corporate PPA | Local PPA contracts increasing |
| Tokyo | Concentrated demand, many PPA buyers | Corporate PPA priority | RE100 companies concentrated |
| Chubu | Manufacturing hub, active OTC market | Corporate PPA + FIP | Superpeak Swap integration available |
| Hokuriku | Stable electricity prices, high hydro | FIP (stable revenue) | Low market price volatility |
| Kansai | Large demand, nuclear restarts | Self-consumption + PPA | Nuclear increase may depress market prices |
| Chugoku | High curtailment, industrial zone | BESS + Self-consumption | Curtailment countermeasures essential |
| Shikoku | Frequent curtailment, small demand | BESS + Corporate PPA | Consider cross-area PPA contracts |
| Kyushu | Solar surplus, most curtailment | BESS essential + FIP | Daytime curtailment avoidance is key |
Conclusion: From Defense to Offense After FIT
The greatest post-FIT mistake is defaulting to utility buyback continuation. The ¥7-9/kWh buyback rate typically falls below the cost of capital, failing to maximize existing asset value. Converting to corporate PPA or self-consumption, or combining repowering with FIP transition, offers the potential to improve IRR to 8-14%.
"Post-FIT revenue maximization is not merely a choice of exit strategy - it is a redesign of the asset portfolio. Comprehensively evaluating area characteristics, scale, equipment condition, and buyer access to build the optimal combination will determine profitability for the next 20 years."
