12 Flexible Ramping Product
On November 1, 2016 the ISO implemented two market products in the 15-minute and 5-minute markets: Flexible Ramp Up and Flexible Ramp Down uncertainty awards. These products provide additional upward and downward flexible ramping capability to account for uncertainty due to demand and renewable forecasting errors. In addition, the existing flexible ramping sufficiency test was extended to ensure feasible ramping capacity for real-time interchange schedules.
