When system load is decreasing, what action should a Balancing Authority take to limit inadvertent accumulation?

When system load is decreasing, a Balancing Authority should decrease transactions into their system to maintain balance and limit inadvertent accumulation. This action is essential because when load decreases, the generation output may exceed consumption if not carefully managed. By decreasing the transactions into their system, the Balancing Authority can reduce the amount of energy that is being brought into the grid, thereby aligning generation and load more closely.

Adjusting transactions helps in preventing an oversupply situation where generation exceeds demand, which can lead to undesirable frequency deviations and potential system instability. Ensuring that the energy being imported does not exceed the declining load will contribute to a more stable grid operation.

In contrast, increasing transactions would exacerbate the imbalance by further increasing supply relative to demand, leading to an accumulation of surplus energy. Increasing generation without considering load would also risk oversupplying the system. Limiting communication with marketers would not be beneficial in managing system operations effectively, as clear communication is critical for coordinated actions between entities in the energy market.
