This is from last year...
"For the last two seasons, each team was getting 2.89 power plays per game. This year, the number has risen to 3.26, the highest rate since 2013-14.
Power-play efficiency also continues to trend upward. But that has been happening pretty steadily for 25 years, from a low of 15.08 percent in 1997-98.
Still, after hovering around the 20 percent mark for the last five seasons, this year's power-play success rate has jumped to 22.42 percent. It's the fifth-highest conversion rate since this data was first recorded in 1963-64. The other four years were all between 1978 and 1983 — think stand-up goalies and Gretzky setting up teammates from his office behind the net. And they're not much higher: the all-time record is 22.94 percent in 1982-83.
