| Description: | This NPRR modifies the Hub Bus and Load Zone definitions and price calculations to account for the current usage of power flow buses as opposed to Electrical Buses in the DAM and CRR Auction systems. In some cases there can be differences between power flow buses and Electrical Buses, and it is more suitable for power flow buses to be used. Real-Time currently uses Electrical Buses for the Hub and Load Zone calculations. Further, the rewritten formulas provide clarification for the scenario when buses are de-energized in contingency analysis. |
| Reason: | Addresses current operational issues |
