Power Plays and Penalty Kills: Key Metrics in Hockey

9 August 2026

Hockey is a game of speed, skill, and strategy. But if there’s one aspect that can swing momentum in an instant, it’s special teams—specifically power plays and penalty kills. Whether you're a die-hard fan, a stats geek, or just trying to impress your friends during game night, understanding these key metrics can give you a deeper appreciation for the game.

So, grab your jersey, settle in, and let’s dive into the fascinating world of power plays and penalty kills!

? What Is a Power Play in Hockey?

A power play happens when one team has more players on the ice due to an opponent taking a penalty. It’s like playing a game of tag when your opponent is tied to a chair—your chances of scoring just skyrocketed!

When a team goes on the power play, they have a golden opportunity to capitalize. But not all power plays are created equal. Some teams dominate with crisp passing and deadly accuracy, while others struggle to generate any real pressure.

Key Power Play Metrics

To measure how effective a team is on the power play, we look at a few important stats:

1. Power Play Percentage (PP%)

This is the bread and butter of power play stats. It’s calculated as:

> Power Play Goals / Power Play Opportunities × 100

For example, if a team scores 30 power play goals on 150 chances, their PP% is 20%. A good power play typically hovers around the 20-25% range, while an elite one can creep into the 30% territory.

2. Power Play Goals (PPG)

Simple—how many goals has a team scored with the man advantage? More goals mean a more dangerous power play.

3. Power Play Opportunities (PPO)

This number tells you how often a team gets to test its power play. A team that draws a lot of penalties has plenty of chances to rack up goals.

4. Power Play Efficiency

Is a team capitalizing on their time with the extra skater? You can have 50 power play chances, but if you're not scoring, it doesn’t mean much. Efficiency is about making the most of the opportunities you get.

⛔ What Is a Penalty Kill in Hockey?

On the flip side, there’s the penalty kill (PK). This is when a team is down a player due to a penalty and has to defend against a power play. Think of it like a survival challenge—you're outnumbered, and your only goal is to hold the fort until your teammate escapes the penalty box.

Some teams are lockdown killers, frustrating their opponents and even scoring short-handed goals. Others? Well, they might as well just open the net and invite the other team in.

Key Penalty Kill Metrics

Just like power plays, penalty killing has its own set of important stats:

1. Penalty Kill Percentage (PK%)

The ultimate measure of a team’s ability to survive on the kill. It’s calculated as:

> Penalty Kills / Opponent’s Power Play Opportunities × 100

For instance, if a team successfully kills off 120 of 150 power plays, their PK% is 80%. A strong penalty kill is usually above 80%, while anything below 75% might raise some concerns.

2. Short-Handed Goals (SHG)

These are goals scored by the penalty-killing team despite being at a disadvantage. It’s the ultimate “take that!” moment. Some teams thrive in these situations, turning defense into unexpected offense.

3. Penalty Kill Efficiency

If a team is constantly killing penalties without allowing many goals, they’re doing something right. Efficiency here is all about limiting quality scoring chances and keeping opponents frustrated.

? Why Special Teams Matter

You might be thinking, “Alright, but how much do power plays and penalty kills REALLY impact a game?” The answer: More than you might realize!

Hockey is often won and lost on special teams. A dominant power play can punish opponents who take bad penalties, while a stellar penalty kill can erase mistakes and keep the team in the game.

Momentum Swings

Ever seen a team score a power play goal and suddenly look unstoppable? Or a team kill off a long 5-on-3 and immediately start buzzing around the ice? Special teams create huge momentum shifts that can define a game.

Playoff Success

In the playoffs, where games are tighter and every mistake is magnified, special teams become even more crucial. A hot power play or a ruthless penalty kill can be the difference between lifting the Stanley Cup or hitting the golf course early.

Worst Power Plays Ever

?‍♂️ The 1997-98 Tampa Bay Lightning had just an 8.6% power play. That’s basically a free kill for the other team.

?‍♂️ The 2021-22 Arizona Coyotes posted a dismal 13.9%—only slightly better than flipping a coin.

Best Penalty Kills Ever

? How Teams Improve Their Special Teams

So, how do teams become special teams powerhouses? Here’s what separates the best from the rest:

Power Play Strategies

✅ Puck Movement – Quick, crisp passing forces defenders out of position.
✅ Net-Front Presence – Screening the goalie and jumping on rebounds leads to dirty goals.
✅ Shooting Mentality – More shots = more chaos = more goals.

Penalty Killing Strategies

✅ Aggressive Forecheck – Pressuring the puck carrier can force mistakes.
✅ Shot Blocking – Sacrificing the body to prevent scoring chances.
✅ Smart Stick Work – Taking away passing lanes and deflecting shots.

? Final Thoughts

Power plays and penalty kills may just be parts of the game, but they are often the difference between a win and a loss. Whether your team is lighting it up with the man advantage or shutting down opponents on the PK, these moments can define seasons and championships.
