BCTC Business Function
• Created by BC Government in 2003 to address BC Energy Plan objectives and meet FERC requirements for Energy Trade
• Separate business entity with independent Board and governance structure
• Owns no Transmission or Distribution Assets
• Is accountable to the regulator for transmission operations and asset management/ maintenance including capital investment planning and execution
• Provides asset management services to BC Hydro Distribution for distribution substation assets – from HV step down transformer bushing – on a fee for service basis
• Offers Generation Dispatch and Distribution Operations to BCH on a fee for service basis
• Owns $150M assets - control facilities/systems, business systems and equipment (determines risk profile)
• Regulated utility offering Wholesale Transmission Services and recovery of transmission operations/asset management costs through rates

IT Systems
• Indus Passport• Contains all relay inventory
• Inventory is based on systems ie 5L81 Primary, not relays
• Initiates all preventative maintenance based on maintenance standards
• Issues – software version control, individual relay serial numbers
Maintenance Standards
Cover all relay systems
Detail maintenance required, intervals and job site time
Records retained on Doble CART
Future records to be recorded on mobile computing unit
Establish Preventative Maintenance Budget

Guiding Strategies – NERC and WECC Control Areas
March 25, 2008BCTC Protection and [email protected]
Page 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 Strategies
• Safe Operation
• High Reliability
• Low Cost
• Efficient Maintenance Practices (RCM)
• Search for low hanging fruit to improve efficiencies
March 25, 2008BCTC Protection and [email protected]

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
