Y10-CC coal is still displaced, despite a reduction in CO2 emission cost. The LCOE spread between wind and solar PV becomes tighter with an increase in renewable costs, offset by increased ITC for solar. This illustrates that the LCOE spread is tight between wind and solar PV and subsequently sensitive to parameter assumptions.
