About BC Transmission Corporation
BC’s Independent Transmission Company:
Established in 2003 Crown corporation, 100%
government-owned
Responsible for planning,
constructing, operating and maintaining the Province’s publicly
- wned electrical transmission
system
Plan the long-term expansion of the
transmission system

Planning the System
Interconnect new generation Maintain reliability Meet growth

The Transmission System in BC
System Snapshot:
18,336 km of transmission lines (60
kV - 500 kV)
291 switching, distribution and
capacitor stations
1 primary control centre and one
backup control centre
169 microwave and fibre-optic sites 75,000 hectares of right-of-way Interconnected to Alberta and
the Pacific Northwest

Planning Objectives
Provide cost-effective, safe and
reliable transmission in a socially and environmentally responsible manner
Serve Firm Load Connect Generation Meet Point To Point Obligations Manage Uncertainty

Planning Uncertainties
Timing, location and size (capacity) of
generation additions
Timing, location and size of demand
for electricity
Long lead times for design, approval
and construction of new high voltage transmission lines - e.g. new transmission lines may take 7-10 years to go through the design, approval and construction process while some types of generation only take a couple of years

Planning Challenges
Most Transmission facilities were built between 1940-1980
Many facilities are reaching their capacity
limits
Some assets are reaching the end of their
useful lives
A Unique System
Rough Terrain Regionally dispersed Challenging climate

Transmission Planning Process
- BC Hydro Network
Integrated Transmission Service Application (Long- Term Acquisition Plan Load Forecast & Resource Plan)
- Fortis Wheeling Agreement
- Interconnection requests
- Point to Point Requests
- Model system under various
scenarios and evaluate performance using North American Electric Reliability Corporation and Western Electricity Coordinating Council criteria
- If upgrade is required, identify
and evaluate alternatives to upgrade the system to provide the required capacity
- Project included in BCTC’s
Capital Plan
- Project initiated to conduct
detailed planning studies, conduct consultation and
- btain required regulatory
approvals

BCTC Planning Processes
Long-Term Transmission Vision:
New process Provide 30 year perspective on transmission
needs, technology and investments required to sustain the transmission system
Developed new Long-term Planning tool to
model a variety of scenarios
Informed by outcomes of Commission’s
Inquiry
SLIDE 13

Long-Term Electricity Transmission Inquiry Inquiry Provides:
An open forum for public input and debate Opportunity to identify “need” earlier in the
planning process
Ability to take a provincial perspective Alignment with regional planning initiatives

Integrating Inquiry Outcomes
Transmission 2040: BCTC’s Long-term Transmission Vision 10 Year Capital Plan Approved Projects Broad 30 Year Perspective – high level planning looking at location, volume & timing of needed 230 and 500 kV transmission enhancements 10 Year Project Outlook – more detailed planning studies including power flow modeling system stability and voltage studies Inquiry results
