HYDRO, TIDAL AND HYDRO, TIDAL AND GEOTHERMAL PROJECTS: GEOTHERMAL PROJECTS: Factors Influencing Factors Influencing Development Development • New transmission segments in SE

Alaska & BC• Load Growth in SE Alaska• Opportunities to displace current

high-cost diesel• Opportunities to bid Alaskan-

generated power into calls for power in BC & Lower 48

TIDAL POWER: TIDAL POWER: INFORMATION NEEDSINFORMATION NEEDS• Location map including proposed

interconnection• Project layout and description• Generation technology• Installed capacity and annual

generation • Schedule and cost of power• Environmental assessment• Risk assessment

REALITIES OF THE MARKET REALITIES OF THE MARKET IN BC AND LOWER 48IN BC AND LOWER 48• Entry to the Market is the AK-BC

Intertie + Interconnection with BCTC Transmission

• Market opportunities include:–Sale to BC Hydro–Sale to PowerEx, marketing arm of BC Hydro for resale to Lower 48–Sale to mining interests in NW BC to firm up run-of-river projects–Sale to utilities in Pacific Northwest & California
