Generator operating control centers with how many MW must pass a satellite phone test?

In the context of generator operating control centers, the requirement to pass a satellite phone test is specifically linked to the capacity of the generator. For a generator operating at or above 500 MW, it is critical to have reliable communication systems, such as satellite phones, for effective coordination and response during emergencies or system disturbances. This capacity threshold reflects the importance of having robust communication protocols in place for larger generators, which can significantly impact grid stability.

Generators below this threshold may have less impact on the grid and therefore may not be subjected to the same stringent communication requirements, reflecting the principle that risk management and safety measures should correspond to the potential consequences of a failure in operation. The need for such testing reinforces the emphasis on preparedness and reliability in operations for larger facilities, ensuring that they can maintain effective communication under various conditions.
