What does a positive ACE indicate when dealing with balancing authorities?

• A. That surplus generation exists
• B. That generation should be reduced
• C. That the area is in an energy deficit
• D. That scheduled interchange should increase

Answer: (B)

A positive ACE (Area Control Error) indicates that the generation in a balancing authority area exceeds the scheduled generation requirements. This implies that the area is producing more electricity than it needs to meet its load and obligations. In this scenario, the appropriate response would be to decrease generation to bring the balance back into alignment with the expected levels, effectively addressing the surplus generation. In the context of the other choices, a positive ACE does not point to an energy deficit or a need for increased scheduled interchange, as these would suggest that there is insufficient generation to meet demand. Instead, it emphasizes the necessity for the balancing authority to adjust generation downwards to mitigate the excess and maintain system reliability. Therefore, acknowledging the need to reduce generation is the core action indicated by a positive ACE.
