Two competing proposals to build a pipeline connecting Alaska to Alberta have concluded their 90‐day open season bids. An Alaskan joint venture created by BP and ConocoPhillips envisions a 2,730 km pipeline capable of shipping 4.5 bcfpd, at a project cost of $35 billion. The other proposal, sponsored by TransCanada and Exxon Mobil, envisions a similar pipeline and similar volumes, with an estimated project cost between $32 billion and $41 billion. Both are keeping bidders’ identities and bid conditions confidential pending further negotiations.
