TransCanada’s GTN system files uncontested settlement of its general rate case with FERC

CALGARY, Alberta –November 1, 2007 – TransCanada Corporation (TSX, NYSE: TRP) (TransCanada) today announced that Gas Transmission Northwest (GTN) has filed a Stipulation and Agreement with the Federal Energy Regulatory Commission that comprises an uncontested Settlement of all aspects of its 2006 General Rate Case.

If the Settlement is approved by the FERC, the full-haul (Kingsgate-to-Malin) rate on GTN’s    mileage-based system will be US$0.33 per Dekatherm, up from the US$0.263 per Dekatherm full-haul rate approved in the 1996 Settlement of GTN’s last rate case. The new rate would be effective retroactive to January 1, 2007, pending approval by the FERC.

Under terms of the Settlement, GTN’s rates are subject to a rate moratorium and may not be changed until January 1, 2012. GTN is required to file a rate case with new rates effective no later than January 1, 2014.

The parties further agreed to a depreciation rate of 2.0 per cent for all transmission plant on the GTN mainline.

“TransCanada is very pleased to negotiate a mutually agreeable settlement with its GTN customers,” says Hal Kvisle, TransCanada president and chief executive officer. “TransCanada is focused on working with its customers to find innovative solutions to meet their ever-changing needs.”

GTN anticipates FERC will issue an order early in the first quarter of 2008.
