Hurricane Fly in the Champion Hurdle. On 13 March, Annie Power started 11/8 favourite for the World Hurdle, ahead of Big Buck's, who was attempting to win the race for the fifth time. She was held up by Walsh before moving up to dispute the lead at the last. In the closing stages the race developed into a struggle between Annie Power and the six-year-old gelding More Of That, both of them unbeaten at the time, with the latter prevailing by one and a half lengths. After the mare's first defeat, Mullins admitted that she had been beaten by a better horse on the day but added that she was "probably a little keen to be a three-miler".

On 2 May at Punchestown, Annie Power attempted to repeat her 2014 success in the Mares Champion Hurdle. Starting at odds of 2/9 against six opponents, she led from the start and drew clear over the last two hurdles to win by ten lengths from her five-year-old stablemate Anafilet. 2015/2016 National Hunt season Following another lengthy absence, Annie Power returned to the track in a minor event at Punchestown on 17 February 2016. She was made the 1/20 favourite against two opponents and led from the start to win by six and a half lengths from Legacy Gold.
