We develop a metric to quantify the sub-hourly variability cost of individual wind plants and show its use in valuing … variations (termed load following) for 20 ERCOT wind plants was $8.73±$1.26 per MWh in 2008 and $3.90±$0.52 per MWh in 2009. Load … following variability costs decrease as capacity factors increase, indicating wind plants sited in locations with good wind …
