July 31 (Reuters) - Canadian pipeline operator TC Energy ( TRP )

beat analysts' estimates for second-quarter profit on

Thursday, helped by increased natural gas and power demand.

On an adjusted basis, the Calgary-based company earned 82

Canadian cents per share for the three months ended June 30,

compared with analysts' average expectation of 78 Canadian

cents, according to data compiled by LSEG.
