What is the maximum percentage of synchronized generating capability that should be added in blocks during restoration?

The maximum percentage of synchronized generating capability that should be added in blocks during restoration is identified as 5%. This guideline is critical in ensuring a measured and controlled approach when reinstating generation capacity following an outage or system disturbance.

By limiting the increase in generation capability to 5% at any one time, it helps manage the stability of the power system during restoration. This cautious approach minimizes the risk of overloading the existing infrastructure and prevents potential cascading failures that can arise from rapid imbalances between supply and demand. Additionally, this gradual increase allows for better monitoring and assessment of system response, confirming that the returning generation is synchronized properly with the grid before additional capacity is brought online.

Establishing a restoration plan that adheres to this limit contributes to maintaining system reliability and integrity, supporting the overall objectives of resource management in restoration scenarios.
