Curtailment Report

The report is for owners or possible owners of solar power plants.

Sunpulse has developed a quantifiable methodology to ascertain the 30 year cash flow effect of an electricity company curtailment.

We combine our curtailment calculation with a probability scenario dependent on the size and location of the solar power plants in the vicinity of the solar plant being studied. We are tracking over 460,000 power plants throughout Japan. 


  • Quantifiable output calculation.
  • Sunpulse has mapped all power generation asset types including Solar, Wind, Geothermal, Thermal, Thermal Biomass, Biomass, Hydropower, Pumped Hydro and Nuclear.
  • We have a partnership with a policy specialist firm to include the latest updates from the evolving regulatory framework including dispatch order and other variables.
  • Engineering assumptions.
  • Based on feedback from solar power plant owners experience in the market.
  • Kyushu Electric, Chubu Electric, Tohoku Electric, TEPCO and HEPCO Power Company areas.
  • Other electrical company areas depend on requests and specific case-by-case scenarios.
  • We include a login to our bespoke curtailment research platform, Rotormaps.
