Under-Frequency and Over Frequency Conditions Clause Samples
The "Under-Frequency and Over Frequency Conditions" clause defines the procedures and responsibilities that apply when the frequency of an electrical grid falls below or rises above specified operational thresholds. In practice, this clause typically outlines the actions that must be taken by parties, such as reducing or increasing generation, disconnecting certain loads, or activating frequency response mechanisms to stabilize the grid. Its core function is to ensure grid reliability and safety by providing a clear protocol for responding to abnormal frequency events, thereby minimizing the risk of widespread outages or equipment damage.
Under-Frequency and Over Frequency Conditions. The New York State Transmission System is designed to automatically activate a load- shed program as required by the NPCC in the event of an under-frequency system disturbance. Developer shall implement under-frequency and over-frequency relay set points for the Large Generating Facility as required by the NPCC to ensure “ride through” capability of the New York State Transmission System. Large Generating Facility response to frequency deviations of predetermined magnitudes, both under-frequency and over-frequency deviations, shall be studied and coordinated with the NYISO and Connecting Transmission Owner in accordance with Good Utility Practice. The term “ride through” as used herein shall mean the ability of a Generating Facility to stay connected to and synchronized with the New York State Transmission System during system disturbances within a range of under-frequency and over-frequency conditions, in accordance with Good Utility Practice and with NPCC Regional Reliability Reference Directory # 12, or its successor.
