Call for Comments to the Proposed General Amendments for the Monitoring of Forecast Accuracy Standards on Matters Relating to Enforcement Proceedings and Actions (ORCP-WR-WM-22-12)
Tue, 20 Dec 2022

The Rules Change Committee (RCC) is inviting all WESM Members and interested parties to submit comments to the PEM Board-approved Proposed General Amendments to the WESM Rules and WESM Manual on Procedures for the Monitoring of Forecast Accuracy Standards for Must Dispatch Generating Units (FAS Manual) on Matters Relating to Enforcement Proceedings and Actions (ORCP-WR-WM-22-12).

The proposed amendments seek to:

  1. address the gap between the FAS Manual and the actual procedures and practices being adopted to implement the provisions of the said Manual;
  2. ensure compliance with the requirements set forth in the DOE DC2022-05-0015 that seeks to include in the FAS-related enforcement proceedings/actions the must dispatch generating units with issued FCATC;
  3. define with more clarity the reference data for the calculation of the forecast percentage error and other terms used in the Manual;
  4. address some unique conditions, situations, or circumstances affecting the compliance of the must dispatch generating units but are not otherwise included in the current FAS Manual;
  5. give considerations or exemptions for some plants who have just commenced operations and have low chance of passing the mean absolute percentage error (MAPE) or the Percentile 95 of the forecasting error (Perc95) due to their limited time of participation in the WESM within the subject monitoring year; and
  6. add provisions that will promote due process before any sanction is imposed relative to a finding of breach of MAPE and PERC95.

 

The WESM documents for amendments are:

  1. WESM Rules; and
  2. WESM Manual on Procedures for the Monitoring of Forecast Accuracy Standards for Must Dispatch Generating Units (FAS Manual)
