2. Background
The current implementation of the PFV tool includes the ability to perform the GTL impact calculation based upon;
1) GLDF within BA
2) native/transfer for markets/BAs with multiple Local Balancing Authorities (LBAs)
These two methods were included because they are utilized today with the current congestion management (e.g. CMP)

3. Issues
Depending upon the final prioritization methodology implemented, having multiple ways to calculate impacts will likely create non-comparable treatment between entities
The need for the native/transfer implementation is unclear, depending upon the final Permanent Solution. The impact results between the standard GTL GLDF and native/transfer will be different based upon current IDC/TLR calculations.
Therefore, the curtailment responsibility assignments will be different depending upon the calculation type.

6. Recommendations
The BPS (or sub-team with OATI participating) should review and recommend the “impact calculation” once the Permanent Solution is being finalized as it has equity impacts depending upon how it is implemented.
The BPS should determine whether multiple impact calculations should be developed (or allowed), if a common prioritization method is ultimately approved.
If there are multiple impact calculation methods implemented, and selectable by entities, the BPS should set rules that outline ability to utilize the different methods.
