5. 5 NERC Near-Term Actions To Assure Reliable Operations Failures of System Monitoring and Control Functions: Review and as necessary, establish a formal means to immediately notify control room personnel when SCADA or EMS functions, that are critical to reliability, have failed and when they are restored.  Establish an automated method to alert power system operators and technical support personnel when power system status indications are not current, or that alarms are not being received or annunciated.

6. 6 In-House Implementation Generating a pseudo Alarm/Event every 5 minutes 08/16/04 13:00:01 PDT DCTSta A/E CHECK SUCCESS... AE 5 Min. Success 08/16/04 13:05:01 PDT DCTSta A/E CHECK SUCCESS...

Success “Check” process to check A/E logs Sending automatic notifications How about…  Other critical processes?  Other system characteristics?

7. 7 NERC Cyber Security Standard NERC Urgent Action Standard 1200 presents standards to “monitor” and protect critical cyber assets At Sempra, we take compliance seriously –SDGE Self-Certification – 3/1/04 –“Substantial Compliance” – 3/1/04 –“Full Compliance” – 3/1/05
