FAIRBANKS - Both the TransCanada and Denali natural gas pipeline projects expect to file for a federal permit in 2012.
The Fairbanks Daily News-Miner reported both companies are moving ahead with plans to conduct what is called an "open season" next year that will influence the pace of the project estimated to cost $40 billion.
Denali is the joint effort of BP and ConocoPhillips.
TransCanada earlier this year took on Exxon Mobil as a partner in its project, which is the one approved by the Legislature and then-Gov. Sarah Palin with $500 million in state financing.
The state approval does not prevent Denali from seeking authorization from the Federal Energy Regulatory Commission.
