02: Please supply any comments related to the Uncertainty Factor section (3).

The Uncertainty Factor section effectively outlines its role in addressing variances between forecasted and actual loads and resource performance. However, the example in Table 1, while comprehensive for those familiar with the subject, could be enhanced for clarity and broader stakeholder understanding. To make the example more informative, SRP recommends including a narrative to accommodate the example in Table 1 to explain that the reduction of the Uncertainty Factor from 10% to 7.50% for participants 'A' and 'B' helps achieve a balance in the subregion's total capacity, with a total of 0 indicating a match between capacity needs and availability.

Additionally, to ensure stakeholder understanding of the impact of the Uncertainty Factor in the Table 1 example and how the Sharing Calculation Result is derived, it may be helpful to include and/or reference the WRAP Sharing Calculation Formula within the BPM.

Furthermore, clarity on the basis for setting the default Uncertainty Factor at 10% would be beneficial. SRP recommends the WPP include further details or data to provide clarity and justification of how specific percentages were determined. This information may help stakeholders understand the basis and rationale of these values.  

Lastly, SRP recommends that the BPM provide guidance for situations where the Uncertainty Factor is reduced to the minimum threshold of 3%, yet the subregion's total capacity remains in a deficit.

General Comment

SRP is encouraged by the WPP's ongoing efforts in the developing of WRAP BPMs.

SRP recommends the WPP consider if the level of uncertainty in forecasting load and generation would increase, not decrease, in scenarios where participants are experiencing a deficit. SRP’s understanding is that deficit conditions, indicating a shortfall in resources to meet load requirements, would lead to a more unpredictable operational environment. Therefore, SRP encourages the WPP to provide an example and/or explanation illustrating why the Uncertainty Factor decreases in such scenarios. This may help stakeholders resolve any confusion about the application of the Uncertainty Factor in different operational contexts.
