Black Start units are critical components of the power grid, as they provide the necessary support to restore service in the event of a widespread outage. Testing these units ensures they are operational and can perform effectively when called upon. According to industry standards and guidelines, Black Start units are required to be tested on a yearly basis. This testing frequency allows for adequate inspection and maintenance while ensuring that any potential issues are identified and addressed in time to maintain system reliability and safety. Regular testing at this interval also aligns with best practices in power system operations, helping to ensure readiness and dependability in emergency situations.
