A generator must be equipped with a governor if it is over how many megawatts?

A generator must be equipped with a governor if it exceeds a certain output capacity to ensure effective and reliable performance within the grid. In this context, the requirement for a governor is set at a threshold of 10 megawatts. The governor plays a crucial role in regulating the generator's output to match the demand and maintain system stability. It automatically adjusts the fuel or energy input to the generator in response to changes in load, which helps prevent fluctuations that could lead to instability or outages in the electrical grid.

Generators below this threshold may not require a governor because their output is typically not significant enough to impact the overall grid dynamics. However, for generators above or equal to 10 megawatts, having a governor is essential for ensuring that they can respond effectively to variations in system demand and maintain frequency control. Therefore, the correct threshold for requiring a governor on a generator is 10 megawatts.
