NPRR477 Exception for Block Load Transfers at Presidio
ReasonDespite the installation of the NaS battery at Presidio and the completion of the new 69 kV line from Alamito Creek to Chinati to Presidio, Load growth in the area still requires that the 69 kV line flowing from CFE into the Gonzales substation must be constantly energized in order to maintain connectivity and minimize Outage restoration times. As a result, there is a small of amount of energy that flows out of CFE into ERCOT that is not registered by the AEP meter at the Gonzales substation and, therefore, not included in the ERCOT Settlements process. Historically, CFE has not sought reimbursement for this energy but began invoicing AEP Energy Partners for the energy in May 2012. The May invoice was for less than three MWh. Currently, this energy cannot be treated as a BLT because the Protocols require that ERCOT must have issued a VDI in order to settle the energy as a BLT. Therefore, AEP is seeking to create an exception for this energy so that can be settled as a BLT.

Summary
This Nodal Protocol Revision Request (NPRR) establishes an exception to the Verbal Dispatch Instruction (VDI) requirement for Block Load Transfers (BLTs) that will only be applied to energy flowing from the Comisión Federal de Electricidad (CFE) into the BLT Point at Presidio that is necessary to maintain reliability in that area.
