Hydropower for a Resilient Grid (IMAGE)
Caption
When one power plant unexpectedly goes off-line it can cause a frequency drop below 60 Hz for the entire grid, called the arresting period. This phase can be disastrous if not counteracted within seconds. Not all types of power have a fast response rate but hydropower does. It can ramp up and respond to frequency changes, allowing the grid to rebound and eventually recover back to its normal state.
