Hydro-Québec reported first-quarter net income of C$1.64 billion, up C$101 million from the C$1.54 billion reported in the same quarter of 2017.

"The smooth operation of our generating and transmission facilities allowed us to maintain a strong volume of net electricity exports and post our best first-quarter performance to date in a context of normal temperatures," said Jean-Hugues Lafleur, Hydro-Québec executive vice president and chief financial and risk officer.

Net electricity exports for the most recent quarter increased to 9.8 TWh for C$486 million, up C$15 million versus the same period of 2017, according to a May 11 earnings release.
