SRP values the approach of the BPM 102 to establish capacity needed to meet the reliability metric. For consistency and clarity, SRP recommends specifying the Loss of Load Expectation (LOLE) target as “1 event-day in 10 years LOLE per season” throughout the document. This adjustment may help ensure a common understanding among stakeholders.

APS has identified some inconsistencies in the definition of LOLE Study and the description used throughout the body of BPM 102. The definition says it is a “…single event day of loss of load in ten years reliability metric for each Month of the Binding Seasons, while in Section 2 & 5 “…no more than a single event-day of loss of load in ten years during the Binding Seasons, in Section 7 as “... one event-day in ten years reliability threshold.”, and in Section 8 inside the FSPRM calculation the UCAP 1-in-10 “…UCAP required to meet the reliability for a specified Month in a Binding Season. It is hard to clearly understand what the metric is when we say 1-in-10 with varying definitions.

The term Load Data should be changed to Historical Load Data to reflect the final approved version of BPM 101 and its associated Definitions.
