TransCanada Announces Completion of the Guadalajara Pipeline

CALGARY, ALBERTA--(Marketwire - June 20, 2011) - TransCanada Corporation (TSX:TRP) (NYSE:TRP) (TransCanada) today announced that its US$360 million Guadalajara Pipeline has been completed. The entire capacity of the 307-kilometre (192-mile), 30-inch-diameter pipeline is held under a 25-year contract with Comisión Federal de Electricidad (CFE), Mexico's state-owned electric company.

"The Guadalajara pipeline represents key infrastructure that will allow CFE to continue developing a natural gas-fired electricity generation fleet in the rapidly growing central region of Mexico," said Russ Girling, TransCanada president and chief executive officer. "We are very pleased to be part of this overall development plan."

"Completion of the Guadalajara pipeline represents another milestone in TransCanada's ongoing capital program," Girling continued. "Guadalajara is TransCanada's second pipeline investment in Mexico and highlights our ability to complete pipeline projects in the country which positions us well for future opportunities."

The Guadalajara pipeline connects to an LNG regasification facility located near Manzanillo, in the state of Colima. It has a capacity to transport 500 million cubic feet of natural gas per day to a nearby CFE owned power plant and 320 million cubic feet per day to the Pemex-owned national pipeline system near Guadalajara, in the state of Jalisco.

TransCanada has put into service seven other major projects in the last year. The Keystone Pipeline System Phases I & II are delivering oil; the Groundbirch and Bison natural gas pipelines are transporting natural gas to market; Maine's largest wind project - Kibby Wind - became fully operational in late October; and the Halton Hills Generating Station in Ontario and Coolidge Generating Station in Arizona have begun producing power.
