Reason For Revision
 

Currently, storage resources may be unable to deliver flexible ramping up awards due to lack of state-of-charge.  This PRR update adds the Flex Ramp Up term to the state-of-charge formula, ensuring deliverability from storage resources.  This PRR update also includes a minor correction to Section 6.6.2.3.  This is an emergency PRR with an effective date 4/29/2025​​
