Reason For Revision

​

A participant dispute uncovered an issue in which pumped storage hydro resources located in the WEIM balancing authority area were being incorrectly designated as generating resources during intervals in which those resources were pumping as loads, as indicated by those resources having a negative base schedule.  The configuration updates will ensure that a new input reflects pumped storage hydro resources in the WEIM balancing authority area as load resources when those resources are in pumping mode.

 

The BPM configuration guide RT Energy Quantity PC v.5.25 has been updated to reflect a revised formula for the Settlement Interval Resource Base Schedule charge type. The updated formula section also includes a new formula to define the new input: WEIM Pumped Storage Interval Resource Base Schedule.

 

The upstream changes are to be deployed around 5/1/2024.  The effective date of those changes will align to the BPM effective date of 3/1/2023.
