At Sunpulse K.K., we empower investors, developers, and asset managers to thrive in Japan’s complex energy landscape. Specializing in solar energy yield analysis, curtailment strategy, and BESS integration, we offer deep market insight backed by data-driven modeling.
Our high-accuracy yield assessments are trusted by leading financial institutions, IPP developers, and infrastructure investors across Japan. We deliver site-specific forecasts tailored for utility-scale solar PV assets, supporting project bankability and long-term performance.
We navigate the nuances of Japan’s regulatory frameworks—including the Feed-in Tariff (FIT) and evolving Feed-in Premium (FIP) schemes. From shifting policy environments to curtailment risk, our insights help clients stay ahead of regulatory shifts and optimize revenue certainty.
Maximize your plant’s profitability—even in constrained grid areas.
We offer tailored curtailment modeling and mitigation strategies for:
Unlimited curtailment zones
360-hour per year limits
30-day annual curtailment rules
Special focus on high-impact regions: Kyushu, Shikoku, Chugoku, Tohoku.
Drive higher returns by integrating energy storage.
We simulate BESS scenarios to:
Monetize excess solar during peak-price periods
Model grid behavior and storage value under regional rules
Optimize ROI based on forecasted curtailment patterns
Maximise value of your solar assets with BESS simulation and legacy FIT PPA consulting. Many 20-year PPAs are approaching their final decade. We assess:
