How often are blackstart resources required to be tested?

Blackstart resources are essential for electric grid reliability because they provide the capability to restore energy systems from a complete blackout. Due to their critical role, it’s important that these resources are maintained and tested regularly to ensure they will work effectively when needed.

Testing blackstart resources at least every 3 years is a requirement that helps ensure the equipment is operational, the personnel are trained, and the procedures are effective. This time frame strikes a balance between ensuring that the resources are adequately tested and allowing for the maintenance of operational flexibility. Regular testing within this interval helps identify any potential issues or deficiencies that could impede the successful restoration of power in the event of a blackout.

While resources may need to be tested more frequently depending on specific circumstances, a three-year testing interval is a baseline for demonstrating preparedness and reliability in restoration operations.
