OGRR193 - System Voltage Profile Clarification: This Operating Guide Revision Request (OGRR) proposes language to clarify that the ERCOT calculated Voltage Profile is the normally desired scheduled voltage for the specified transmission bus. This OGRR clarifies that the Voltage Profile, calculated and studied by ERCOT, is the normally desired scheduled voltage for the specified transmission bus that a generator or generators at that bus are to maintain. However, the Transmission Service Provider (TSP) has the authority to deviate, for a specified time period; from the normally desired scheduled voltage should the system conditions dictate such deviation.
