How Hockey ChangedThe Vanishing Game
The Power Play Is Disappearing
Referees call about half as many penalties as they did 20 years ago, and the power play’s share of scoring is back where it was in the 1960s. Yet goals are back above six a game. We split every goal since 2005-06 by strength to see where the rebound came from.

- Power plays score more often than they used to (21.6% in 2024-25, the best since the mid-1980s), but there are too few of them to matter much.

How many power plays a game does the NHL have now?
In 2024-25 the two teams in an NHL game combined for 5.41 power plays. That was the lowest since the league started tracking power-play chances in 1977-78. The peak was 11.7 in 2005-06, the first season after the lockout; the late 1980s ran close, with 10.9 in 1987-88.

- 2005-06: First season after the lockout
The 2005-06 spike did not last: by 2009-10 chances were back to 7.4, closer to the late 1970s (6.4 to 7.0). The second slide, from there to 5.41, has no single rule behind it. Minor penalties fell from 12.8 a game in 2005-06 to 6.0 in 2024-25.
Where the scoring rebound came from
Goals bottomed out at about 5.33 a game across 2011-12 to 2015-16 and rose to 6.17 across 2021-22 to 2025-26. With fewer power plays, the extra goals had to come from somewhere else. Empty-net goals matter here: the NHL counts most of them as even-strength goals, and goalie pulls have become far more common.

Continues below
| Strength | 2011-12 to 2015-16 | 2021-22 to 2025-26 | Change | Share of the rise |
|---|---|---|---|---|
| Empty-net goals | 0.22 | 0.36 | +0.14 | 17% |
| Power-play goals | 1.16 | 1.23 | +0.07 | 8% |
| Shorthanded goals | 0.15 | 0.17 | +0.02 | 2% |
| All goals | 5.33 | 6.17 | +0.84 | 100% |
So the hunch mostly holds: the rebound did not come from the power play. About 73% came at even strength into a guarded net, and about 17% came from empty nets, which is the goalie pull changing the end of games. The power play added 8%. (Shares do not add to exactly 100% because of rounding.) The goalie pull’s true share is a little bigger than the empty-net line: the guarded-net bucket still holds the extra-attacker goals scored by the team that pulled its goalie, about 0.1 a game in recent seasons.
Fewer power plays, but better ones
Teams convert more of the chances they get. League power-play success was 17.7% in 2005-06 and 21.6% in 2024-25, the best since 22.1% in 1985-86. A rarer, more skilled power play is still a smaller part of the game: 1.2 goals a game against 2.1 in 2005-06.

What it means for how games are decided
- Special teams decide less. With about six chances a game, the power play produces about a fifth of all goals, down from a third in 2005-06.
- The goalie pull matters more. Empty-net goals went from 0.14 a game in 2005-06 to about 0.4, roughly a third of what the power play produces.
- Season splits are short. 2012-13 (48 games), 2019-20 (cut short) and 2020-21 (56 games) are rates per game, so they still compare, but they carry more noise.

Frequently asked questions
Why are there fewer power plays in the NHL?
Fewer minor penalties are called: about 6 a game in 2024-25 against 12.8 in 2005-06. The season totals cannot say how much is players taking fewer penalties and how much is referees calling fewer.
What is the record low for NHL power-play opportunities?
5.41 a game (both teams) in 2024-25, the fewest since the NHL began tracking power-play chances in 1977-78. 2025-26 was 5.76.
What share of NHL goals are power-play goals?
About 20%. It was 19.7% in 2025-26, down from 34.2% in 2005-06. Every season since 2016-17 has been at 21% or below, a run last seen before 1953.
Did NHL scoring go up because of the power play?
No. Comparing 2021-26 with 2011-16, about three quarters of the extra goals came at even strength into a guarded net, about a sixth from empty nets, and under a tenth from the power play.
