PJM proposes to revise this price to be the “sum of the Reserve Penalty Factors for the 30-minute Reserve Requirement and the Primary Reserve Requirement for each Reserve Zone or Reserve Sub-zone to which it can contribute.”77 This language equates to the highest possible price for Non-Synchronized Reserve if there were no price cap.
