If not listed, convey the voltage violations to the Transmission and Security Operator Create a savecase, use naming convention “SC_RRD(HE)_(DATE) Make at least one detailed log entry per shift that the studies are Voltage being executed. If any new voltage violations are identified that do not have a solution, log the information and notify the Contingencies Transmission and Security Operator of the new violation(s). IF: Unsolved contingencies exists; THEN: Communicate any unsolved contingency to the Shift Engineer and Transmission Security Desk Operator for potential solutions. Some potential solutions could be transmission switching, creation of a manual constraint, bringing on an additional Resource, returning a planned outage, or development of a CMP.
