Assessment Recommendations
Further develop functional backup control center and
evacuation plans. Have all system controllers participate in evacuation
plans.Expand the EMS state estimator model.Upgrade voice and data communications for
evacuation plans.Incorporate a full system restoration drill into simulator
training.Develop a procedures management system.
Assessment Recommendations
Additional frequency points on geographic
display to aid in system restoration and evaluation of
island boundaries if the system separates.Formalize the initial training curriculum for controllers,
including development of learning objectives and
measures for progress.Formalize the evaluation process of promotion.Develop lesson plans for simulator training to facilitate
operator feedback and validate that effective learning
takes place.
Post-Audit Review
Caused us to take a hard look at our overall operation.
Revealed our weaknesses, but also our strengths.
Allowed us to get funding that would otherwise be
unavailable.
Our entire staff now communicates better and works
more effectively because of the “journey”.
The controllers also now have more system visibility.
