Sections Affected

5.7.4.1 and 5.7.4.1.1

Summary

This Nodal Protocol Revision Request (NPRR) replaces the usage of the Wind-powered Generation Resource Production Potential (WGRPP) and PhotoVoltaic Generation Resource Production Potential (PVGRPP) with the High Sustained Limit (HSL) of an Intermittent Renewable Resource (IRR) as reflected in the Current Operating Plan (COP), similar to treatment afforded to Resources that are not IRRs. This NPRR also makes a minor adjustment in Section 5.7.4.1, changing the name of a variable in a formula from HSL to RUCHSL in order to match the variable name in the Protocols to the data value available in the Settlement extracts.
