14. Guiding Strategies – NERC and WECC Control Areas BCTC Protection and Control John.robertson@bctc.com

15. Influence of NERC • Standards • Must ensure minimum standards are in place • Fairly comprehensive for the Bulk Electric System • Must meet Critical Infrasturesture requirements • Must have intervals established • Must be complied with and subject to auditing (every three Years) • Non compliance subject to fines, dependent on severity, BCTC Protection and Control John.robertson@bctc.com

16. BCTC Strategies • Safe Operation • High Reliability • Low Cost • Efficient Maintenance Practices (RCM) • Search for low hanging fruit to improve efficiencies BCTC Protection and Control John.robertson@bctc.com

17. Maintenance Standards • BCTC is developing new standards, main points: • Cover what to look for, not how to do it • Directly Integrate with our mobile computing system used for station inspections and equipment condition assessment • Collects asset health index values to assess trends for asset condition • For P&C values checked include: • For Electro mechanical; • Ensure checks are made per test plans (CART) and deficiencies noted • For Microprocessor: • Ensure inputs and outputs checked (includes trip test) • Ensure settings correct • Ensure breaker failure is functional • Check version and serial number BCTC Protection and Control John.robertson@bctc.com
