Curtailment Impact Report for Solar Power Plant Owners

Sunpulse offers a quantifiable methodology to assess the 30-year cash flow impact of electricity curtailment.

This report is designed for current and prospective solar PV plant owners seeking to understand grid curtailment risk and optimize return on investment.

Data-Driven Curtailment Forecasting

Our model calculates curtailment risk based on:

• Proximity to nearby solar assets
• Local grid congestion at the substation level
• Grid congestion at the N1 Line or regional line level
• Regional utility behavior
• Real-world engineering feedback

We actively monitor over 460,000 power plants across Japan — including PV, wind, geothermal, biomass, hydro, and thermal — to deliver high-resolution, location-specific analytics.
