NPRR1066  Interconnection of Existing Generation Owned by a Municipally Owned Utility (MOU) or Electric Cooperative (EC) Transferring Load into the ERCOT System

This Nodal Protocol Revision Request (NPRR) grants ERCOT the discretion to apply existing standards that are applicable to older Generation Resources registered with ERCOT (a “grandfathered” standard) to an existing generation unit owned by a Municipally Owned Utility (MOU) or Electric Cooperative (EC) that is transferring Load into ERCOT and seeks to interconnect the existing generation unit to the ERCOT Transmission Grid in conjunction with the Load transfer. ERCOT will only apply a grandfathered standard if the MOU or EC provides a written explanation as to why it cannot comply with the standard imposed on new Generation Resources, and demonstrates to ERCOT’s satisfaction that allowing the generation unit to comply with the grandfathered standard is reasonable and will not create a risk to reliability of the ERCOT System. This NPRR also clarifies that, should an MOU or EC interconnect an older generation unit to the ERCOT Transmission System as part of a Load integration, the unit will not qualify the MOU or EC to receive Pre-Assigned Congestion Revenue Rights (PCRRs).
