The solar eclipse is expected to reduce electricity generation output for over 1,900 utility-scale solar photovoltaic (PV) power plants in the U.S. California’s 8.8 GW of utility-scale solar PV accounts for 40% of the country’s total capacity. During the eclipse, California will lose almost half of its solar generation capability and will use hydropower plants and natural gas generation to meet the state’s needs. (EIA)
This event highlights the dependence of solar generation on consistent sunlight exposure. As solar and wind capacity make up a larger share of the generation mix, the market could see increased price volatility due to the unpredictable nature of renewable generation sources.
