Project Profile
Value: US$41,000 Million
Start-up Year: 2020
Location: Canada, USA, Alaska
Capacity: 3 Bcfd
The project would see the construction of a US$20-31 billion, 1715-mile (2760km) 48-in gas pipeline, which could take 10 years (until 2018) to complete, including negotiating and permitting process. The state (Alaska Gasline Inducement Act) proposes a line carrying 4.5 Bcf per day from Alaska\'s North Slope (a new natural gas treatment plant at Prudhoe Bay) to Canada and the USA lower 48 states. The North Slope has proven gas reserves of 35 trillion cubic feet. TRhe provisions for expansions up to 5.9 Bcfd through the addition of compressor stations in Alaska and Canada.
The proposed pipeline would parallel the route of the existing trans-Alaska oil pipeline to a point south of Fairbanks. It would then follow the Alaska Highway, continuing through northern British Columbia to link with the Alberta Hub on TransCanada\'s pipeline grid in northwestern Alberta. The Alaska section would be approximately 750 miles (1,200 km) in length, with 6-13 compressor stations and at least five natural gas delivery points in Alaska. The Canadian section to Alberta would be approximately 965 miles (1,550 km), with 10-19 compressor stations and eight intermediate delivery points in the Yukon. The license grants TransCanada rights to a $500 million state grant and special procedures for state permits. In return, TransCanada agreed to a package of state requirements including special provisions related to pipe expansions and tariff structures.
