Which of the following types of data are BA and RC not required to share with one another?

The relationship between Balancing Authorities (BA) and Reliability Coordinators (RC) involves sharing critical information to maintain the reliability and efficiency of the electrical grid. However, not all types of data are mandated for sharing under the NERC standards.

Generator startup costs do not typically fall within the realm of required information that BAs must share with RCs. While operational dynamics such as load forecasts, real-time system status, and interchange schedules are crucial for maintaining balance, mitigating risks, and ensuring optimal grid operations, the financial particulars related to generator startup can vary widely among entities and are not necessary for real-time grid management or reliability within the established framework.

Thus, this distinction highlights the focus on operational and real-time reliability needs over financial data, underscoring why generator startup costs are not a required sharing item between BAs and RCs. This helps streamline communication and ensures that critical data pertinent to grid stability and operations takes precedence.
