April 29 (Reuters) - TransCanada Corp, the country's No.2 pipeline operator, reported a 35 percent fall in quarterly profit, mainly due to a C$176 million after-tax charge related to its decision to end agreements to buy electricity from coal-fired plants in Alberta.
Net income attributable to shareholders fell to C$252 million ($201 million), or 36 Canadian cents per share, in the first quarter ended March 31, from C$387 million, or 55 Canadian cents, a year earlier.
Comparable earnings, which exclude most one-time items, rose to C$494 million, or 70 Canadian cents per share, from C$465 million, or 66 Canadian cents per share, a year earlier.
