  2. Overview of Presentation � BCTC Who we are • What we do • � Transmission planning today � Transmission planning for 2040 2

  3. 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 owned electrical transmission system � Plan the long-term expansion of the transmission system 3

  4. Planning the System Maintain reliability Meet growth Interconnect new generation 4

  5. 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 5

  6. 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 6

  7. 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 7

  8. 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 8

  9. Transmission Planning Process • Model system under various • Project included in BCTC’s • BC Hydro Network scenarios and evaluate Capital Plan Integrated Transmission performance using North • Project initiated to conduct Service Application (Long- American Electric Reliability detailed planning studies, Term Acquisition Plan Load Corporation and Western conduct consultation and Forecast & Resource Plan) Electricity Coordinating Council obtain required regulatory • Fortis Wheeling Agreement criteria approvals • Interconnection requests • If upgrade is required, identify • Point to Point Requests and evaluate alternatives to upgrade the system to provide the required capacity 9

  11. BCTC Capital Plan 10 year Plan � Describes investments required to meet load growth, interconnect new generation, and sustain and operate the transmission system Plan Total : 1000 $5.3 billion over 10 years 900 800 700 600 Growth $M 500 Sustain BCTC 400 300 200 100 0 F2005 F2006 F2007 F2008 F2009 F2010 F2011 F2012 F2013 F2014 F2015 F2016 F2017 F2018 F2019 Fiscal Year 11

  12. 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 12

  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 13

  14. Integrating Inquiry Outcomes Inquiry results Broad 30 Year Perspective – high level planning looking at Transmission 2040: BCTC’s location, volume & timing of Long-term Transmission Vision needed 230 and 500 kV transmission enhancements 10 Year Capital Plan 10 Year Project Outlook – more detailed planning studies including power flow modeling system stability and voltage studies Approved Projects 14
