Maintaining ACE near zero is essential for grid stability.\u003C\/p\u003E\u003Cp\u003EThe authors find that a doubling of hourly wind generation variance increases average hourly ACE by 2% in BPA, 3.7% in NYISO, and 11.4% in SPP\u2014equivalent to 1.2 MW, 1.8 MW, and 9.35 MW increases in system imbalance, respectively. PJM shows no significant effect, likely due to less granular data. They also show that sudden increases in wind generation are more likely to cause oversupply (positive ACE), while sudden drops lead to undersupply (negative ACE), confirming asymmetric operational impacts.\u003C\/p\u003E\u003Cp\u003ERead Full Story on the \u003Ca href=\u0022https:\/\/epicenter.energy.gatech.edu\/2025\/08\/14\/wind-intermittency-and-supply-demand-imbalance-evidence-from-u-s-regional-power-markets\/\u0022\u003EEPIcenter Website\u003C\/a\u003E\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EThis study examines how short-term variability in wind power\u2014known as wind intermittency\u2014affects real-time electricity system imbalances in U.S. regional power markets.
