2
Current Vancouver Island Electricity Supply
  • 80 of Vancouver Islands electricity is supplied
    by sub-marine cables from the mainland
  • 20 is supplied by six Hydro plants on the Island
  • High Voltage Direct Current (HVDC) cable system
    to the Island is deteriorating (scheduled for
    complete retirement by 2007 - this transmission
    capacity needs to be replaced)

3
The Proposed Pipeline (contd)
  • 140 km natural gas transmission pipeline from the
    Sumas supply hub to an interconnect with the
    Centra transmission system on Vancouver Island
    near Duncan
  • Canadian segment
  • 60km - 44km marine and 16 km on -island

4
Growing Demand for Electricity
  • Forecasted growth 30-40 Megawatts per year on
    Vancouver Island
  • Increase in electricity intensive technologies
    businesses
  • Increased square footage of residential
    structures
  • Increased disproportionate use of electrical
    heating systems versus gas, wood and oil (BC 20
    - VI 40)
  • Need for secure reliable power to attract new
    businesses
  • Population growth 21 since 1991

5
Vancouver Island Electricity Supply Demand
6
Options 2002 - 2007
Option 1 Repair/Replace HVDC cables 230
million New mainland generation 600 (VIGP
1 2 equiv. ) New mainland transmission
upgrades 50 Centra Gas System
upgrades 110 Total 990 million
7
Options 2002 - 2007
Option 2 Demand Side Management 75
million (300 million province wide) Green
Alternative Energy 3.4 billion Biomass,
Wind, Wave, Micro-Hydro No transmission
costs considered Centra upgrade 110
million Total 3.585 billion Capacity Only
(i.e.) no guarantee the power is there when you
need it
8
Options 2002 - 2007
Option 3 GSX Pipeline 260 VIGP 1 (Duke
Point) 300 VIGP 2 (unknown) 300 Total
860 million Shared joint-venture costs
9
Options 2002 - 2007
Option 4 GSX Pipeline 260 million VIGP
(Duke Point) 300 Demand Side Management
75 Green and Alternative Energy 525
Total 1.16 billion Objective to defer VIGP
2 (third plant) 5 to 10 years. Shared joint
venture costs

Georgia Strait Crossing Project
  • New natural gas marine pipeline connection
    between the mainland and Vancouver Island
  • BC natural gas
  • Safest environmental and seismic route
  • Joint project between BC Hydro and Williams -
    share cost
  • Approx. cost - 260 million Cdn.
  • NEB oral hearings begin June 17, 2002
  • In-service date - Oct. 2004

11
Vancouver Island Generation Project
  • Replacement project for the Project Alberni
    Generation Project
  • Site acquisition complete April 2002
  • Submit Application to BC Environmental Assessment
    Office (BCEAO) late Spring 2002
  • Anticipated construction period - Spring 2003-Nov
    2004
  • In-service date of November 2004 is critical

12
Site Criteria
  • Social, environmental and economic considerations
  • Industrial zoning
  • Community support
  • 10 acres flat plus 10-15 acres construction
    staging
  • Fresh water and waste
  • Access to gas pipeline and transmission corridor

13
Site Selection Process
  • 12 sites shortlisted to 4
  • City of Nanaimo, Duke Point (2)
  • Nanaimo Regional District (1)
  • District of North Cowichan(1)
  • Duke Point is the preferred option at this time

14
Delay Consequences Beyond 2004
  • Peak season November - February curtailments
  • major customers, shutdowns, economic dislocation
  • location specific brownouts - North Island, West
    Island, South Island
  • Large customers switch to high polluting fuels
  • Purchases from market - more expensive, more coal

15
Vancouver Island Alternative/Green Generation
  • Wind 10 megawatts
  • Micro-hydro 7-9 megawatts
  • Wave 3-4 megawatts
  • Biomass 200 MW
  • Challenges
  • cost
  • location
  • connection
  • reliability
  • volume

16
Demand Side Management/ Power Smart
  • 1990-2000
  • annual reduction of 2500 GWh of consumption or
    would require 500 MW additional generation
  • 350 million
  • 2002 - 2012
  • annual reduction of 3500 GWh
  • 600 million
  • examples - energy audits, LED, SUCH
