NLC Electrical Grid 2 Practice Test

Load shedding is defined as what?

Automatic shedding of all loads. Deliberate disconnection of critical loads only. Deliberate disconnection of non-critical loads to prevent system collapse. Increasing generation to cover deficit.

Correct Answer:

Deliberate disconnection of non-critical loads to prevent system collapse.

Explanation:

Load shedding is the deliberate disconnection of non-critical loads to prevent system collapse when the available generation cannot meet demand or during a disturbance. By shedding non-essential demand, the grid preserves stability and keeps critical services—like hospitals and emergency systems—operational. The aim is to maintain system frequency and voltage within safe limits, minimizing the impact on society while avoiding a wider blackout. Increasing generation to cover the deficit is not load shedding; it’s trying to meet demand without shutting off loads.
