Strategic planning for utility-scale solar photovoltaic development – Historical peak events revisited

•Across NYS, a wealth of low-value land exists to support utility-scale solar PV.•Solar generation can reduce summer peak demand by up to 9.6% in certain regions in New York.•Regional ramping requirements may increase by up to 151% during sunny winter days.•PV performance during system peak should be retained in capacity valuation of solar.
