MORE REPORTS

Reported Y2K Status

Southern California Edison (SCE) spoke about both nuclear and transmission/distribution matters (T&D). They used the NEI/NUSMG guidance documents as well as the NRC documents. They used risk analysis as a way of determining and prioritising their efforts and also to avoid funding some activities. This was done in lieu of scenario analysis as done by many others.
SCE established a command and control structure to manage their comprehensive programme as well as an active media relations policy.
The objectives of their programme are to minimise the potential of Y2K problems to compromise their operations, maximise their ability to respond to problems and maximise employee safety.
SCE only uses company owned and ready communications systems.
An advantage of the programme is that it has caused them to examine carefully many battery operated systems that had problems undetected by other means.
The only external event of concern is low load. They intend to operate the grid in normal mode. A no maintenance period has been declared around rollover dates.
SCE intends to use hydro facilities to load follow and are rehearsing black restart procedures.
Modern capacitor banks used to maintain voltage and which are digitally controlled will be made inoperable on rollover dates as they have some date problems.
