How often must a Balancing Authority and Reserve Sharing Group review their probable contingencies?

The requirement for a Balancing Authority and Reserve Sharing Group to review their probable contingencies annually is based on establishing a proactive approach to reliability and risk management. This annual review allows these entities to assess and update their contingency plans in response to any changes in system conditions, operational strategies, or potential threats that may have arisen in the previous year.

By conducting this review every year, Balancing Authorities and Reserve Sharing Groups can ensure that their strategies are aligned with current best practices, regulatory standards, and technological advancements. This frequency is intended to strike a balance between being thorough in planning and ensuring that the information remains relevant and actionable, thus enhancing the overall security and reliability of the electric grid.

In contrast, other frequencies such as monthly, quarterly, or bi-annually may not provide the same level of comprehensive scrutiny needed to adapt to evolving circumstances in the energy sector effectively. These alternatives may impose excessive operational burdens or fail to capture the necessary depth of review within a suitable timeframe, thereby diminishing the effectiveness of the contingency planning process.
