Strategic Solar & Storage Consulting for Japan’s Evolving Energy Market

Precision Analytics. Market Expertise. Investment Confidence.

 

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.

 

Solar Yield Analysis for Utility-Scale Projects

 

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.

 

Expertise in FIT, FIP & Non-FIT Market Dynamics

 

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.

 

Curtailment Strategy Advisory

 

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.

 

Battery Energy Storage (BESS) Optimization

 

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

 

Investment Due Diligence for Legacy FIT Assets (2012–2018)

 

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:

  • Contract rollover risks and tariff downgrade exposure

  • Long-term asset value and upgrade opportunities

  • PPA security under future market conditions

 

Custom Modeling for Investors & Asset Managers

 

Gain a competitive edge with bespoke scenario simulations:

  • Evaluate portfolio resilience under grid constraints

  • Incorporate Japan-specific dispatch rules and interconnection caps

  • Design de-risking strategies for solar + storage asset portfolios
