If emergency resources are exhausted, what's the next step a system operator should take?

• A. Drop transmission lines
• B. Put reactor banks in service
• C. Manually shed load
• D. Reduce voltage on the transmission system

Answer: (C)

When emergency resources are exhausted, manually shedding load becomes a crucial step for a system operator. Load shedding is a controlled process used to balance supply and demand on the power grid, particularly during emergency situations where the system is at risk of instability or outages. By shedding load, the system operator can effectively reduce the total amount of electricity consumed, thereby lessening the strain on the power system. This allows for the remaining resources to stabilize the grid and prevents widespread outages or cascading failures. The decision to manually shed load is typically made after other options are exhausted, as it directly addresses the immediate issue of balancing supply with demand while ensuring that critical services can continue to operate. While dropping transmission lines, putting reactor banks in service, or reducing voltage can also be part of system operator responses, these actions may not directly address the immediate need for load balance as effectively as manual load shedding. Dropping transmission lines can lead to wider outages, reactor banks are generally used for voltage support rather than direct load management, and reducing voltage may not reduce demand adequately or may lead to other issues with customer service. Therefore, the correct step in this scenario is to manually shed load.
