Description: This Nodal Protocol Revision Request (NPRR) revises language for the sign convention for Load Resources. This NPRR changes the Nodal Protocols so that low reasonability limit, Low Sustained Limit (LSL), telemetered values, High Sustained Limit (HSL) and high reasonability limit are all positive numbers for Load Resources.
Reason: The proposed NPRR will change the sign convention for Load Resources to a more straight forward approach and will align the Nodal Protocols with the current designs in Energy Management System (EMS) and Market Management System (MMS). It will also align the Nodal Protocols to the current zonal market.
