If a Balancing Authority has an error in entering a Net Interchange Schedule, how much hourly Inadvertent will this cause?

The situation refers to a Balancing Authority entering an incorrect Net Interchange Schedule, which impacts the flow of electricity on the grid. When a Balancing Authority makes an error in this data entry, it generally results in an imbalance between the scheduled and actual electricity flows.

An entry error that deviates from the actual situation can create an unintended surplus or deficit of power. The magnitude of this inadvertent interchange is significant because it reflects an imbalance in the energy supplied versus the energy consumed. The correct answer here indicates that the hourly Inadvertent due to this error is -100 MW.

This means that the Balancing Authority is inadvertently sending too much electricity onto the grid over the hour, which the system did not actually schedule for. Such errors can lead to operational challenges, including potential grid instability and financial implications, making accurate data entry crucial for maintaining system reliability and efficiency.

Other potential answers would reflect different levels of error; however, -100 MW is the specific amount associated with the scenario described, highlighting the importance of precision in scheduling to avoid undue stress on the electrical grid.
