The estimated incremental cost of the additional expansion is approximately $200m with a targeted completion date of early 2014, at which time it is now anticipated that the combined expansions will both be fully completed.
Enbridge currently has a total of $2.4bn of commercial secured expansions of or additions to its regional oil sands system, which will go into service between 2011 to 2014, as well as a significant portfolio of additional projects which are under development to meet oil sands growth.
