TransCanada Corporation: Cartier Wind Energy Delivering Additional Power to Quebec

CALGARY, ALBERTA--(Marketwire - Nov. 29, 2011) - TransCanada Corporation (TSX:TRP) (NYSE:TRP) (TransCanada) today announced the completion of the Montagne Sèche project and phase one of the Gros-Morne wind farm.

Looking forward, we are positioned to complete another $12 billion of new projects that are expected to come into service by 2014."

The five-phase Cartier Wind Energy Project, with a total capacity of 590 MW is being constructed in various communities in the region of Gaspesie, Iles-de-la-Madeleine and the Regional County Municipality of Matane.
