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 code fix upstream to settlements will ensure that the input designates pumped storage hydro resources in the WEIM balancing authority area as load resources when they are in pumping mode.
The BPM configuration guides RT Energy Quantity PC v.5.24.0a and Metered Energy Adjustment Factor PC v.5.16.0a have been updated to reflect a revised definition for the BAResBaseScheduleEnergy variable. The updated description reflects that the data will be under resource type = “LOAD” during intervals in which a pumped storage hydro resource located in the WEIM Balancing Authority Area has a negative base schedule.
The upstream changes are to be deployed around 7/31/2023. The effective date of those changes will align to the BPM effective date of 4/1/2023.
