Clarification for the RRS Limit on Individual Non-Thermal Generation Resources |
This Other Binding Document Revision Request (OBDRR) clarifies that Responsive Reserve (RRS) limit for individual non-thermal Generation Resources will be limited to 125 MW. This value may be updated in the future if it creates any reliability issues or as more operational data and models for such Resources become available. The Performance, Disturbance, Compliance Working Group (PDCWG) reviewed these updates at their September 8, 2020 WebEx-only open meeting. |

Change Shadow Price Caps to Curves and Remove Shift Factor Threshold |
This Other Binding Document Revision Request (OBDRR) makes certain congestion management changes for contingency constraints. No base case or Generic Transmission Constraint (GTC) pricing is affected by this OBDRR. This OBDRR 1) Changes the default Shadow Price caps to curves. The change lowers the value for small violations and raises the value for large violations; and 2) Removes the Shift Factor threshold as a factor for determining eligibility for Security-Constrained Economic Dispatch (SCED) consideration. Currently, a constraint is only eligible for resolution by SCED if at least one Resource exists that has a Shift Factor of greater than 2% or less than negative 2%. This OBDRR also proposes minor cleanup items and simplifications to Section 3, Elements for Methodology for Setting the Network Transmission System-Wide Shadow Price Caps. |
